I have a SAE number, how do I identify what type of part that number is calling out?
SAE numbers can be long and intimidating. We have outlined how to decode these in our blog post Understanding the Universal Language of SAE Fluid Connector Part Numbers. This post will help you determine the characteristics you need to find the Parker part number in our system part number selector. If you have questions about this or require help, please let us know. Email us at tfd.support@support.parker.com.

We also have SAE base numbers shown on our catalog's product pages. If you know the product type that the SAE number is calling out, you can look within that product section of the Catalog 4300 and see the SAE base number listed above the product tables and under the part description. Using the blog post Understanding the Universal Language of SAE Fluid Connector Part Numbers, you can verify the order of the size call outs in reference to the Parker part number size call outs to ensure you identify the correct sizing for the part number.

Does Parker make AN/ AS tube fittings?
No, Parker tube fittings and adapters conform to SAE, not AN/AS standards. Please see our blog post AN 37-degree Flare vs Industrial 37-degree Flare Fittings: What’s the Difference? which explains the differences between AN and industrial flare fittings. Note: Our fittings can be used for ground support but cannot be used for in-air applications.

Do Tube Fittings Division's tube fittings and adapters meet CE and PED?
No, they do not. Please see the EC Directive Pressure Equipment (PED) by 2014/68/EU Statement.


PRESSURE RATINGS
Can I get a higher pressure rated fitting than what is shown in the catalog?
It depends on your application and required design factors. If you classify your application as static, you can multiply our catalog pressure by 1.33 to obtain your static pressure rating using a 3:1 design factor. If something is needed at even higher dynamic pressure, this would have to be quoted. You can contact your local Parker distributor to get a quote. See the Fitting and Adapter Pressure Ratings area of the General Technical section of the Industrial Tube Fittings, Adapters and Tube Fabrication Equipment Catalog 4300 for details on our dynamic and static pressure ratings, what the difference is, the calculations used, tube pressure ratings and more.

What pressure are your parts rated to? Where can I find pressure ratings?
We list the dynamic pressure ratings for our part numbers. You can find the pressure ratings for each part number in the last columns of the part number tables. Our pressure ratings are shown under the corresponding part material (steel, stainless steel, brass) typically as a number that, when noted, will need to be multiplied by 1,000.

More information about pressure ratings can be found in the Fitting and Adapter Pressure Ratings area of the General Technical section of the Industrial Tube Fittings, Adapters and Tube Fabrication Equipment Catalog 4300.

How many times can I reassemble a tube fitting or adapter? How do I know if I can reuse my tube fitting or adapter?
Fitting designs have improved significantly over time, making it easier to assemble and reassemble most connections and conduct routine maintenance without increasing leak paths. However, there are two common types of fittings that rank poor for reusability – JIC/37 degree flare and tapered thread pipe fittings. Get the details on what to look for in order to know if you can reassemble your fitting or not in our blog post How Many Times Can I Reassemble a Hydraulic Fitting?

Turns vs torque – does it matter which I use for assembling my fittings?
It does matter. Going over or under the recommendation can lead to leaks, and this can be easily be done if you are using the non-recommended assembly method (and guessing). To get the details on which method is needed for each end style or thread type, including the why and important considerations, see our blog post Turn vs. Torque? How Making the Right Choice Keeps Your Hydraulic Fitting Connections Leak-Free.

You can also use the blog posts and catalog link from the question above to get specific directions and values for assembling.

Do I need to adjust the torque value when I am using softer tube materials, like brass and aluminum?
Yes, we do recommend you decrease your toque values for soft metal materials. The recommendations for this are noted under recommended torque value tables for each product end type in the Assembly and Installation section of the Industrial Tube Fittings, Adapters and Tube Fabrication Equipment Catalog 4300

Why are Parker's torque values for tube fittings and adapters different from SAE?
SAE provides torque values for controlled testing to establish compliance to SAE performance requirements. They state that the recommended assembly torques can vary by manufacturer. For Parker, in many cases, our performance requirements exceed SAE and therefore our torque values are different as well.

Where can I find detailed port dimensions?
We have detailed port dimensions in the Port Details area of the General Technical section of the Industrial Tube Fittings, Adapters and Tube Fabrication Equipment Catalog 4300 for the following ports:
  •  ISO 6149-1 (SAE 2244-1/DIN 3852, Part 3)
  •  SAE J1926-1 (ISO 11926-1)
  •  ISO 1179-1
  •  ISO 9974-1
  •  NPTF
  •  BSP

(2) Use our blog post Four Easy Steps to Identify Hydraulic Threads to train you and your team to identify threads on the jobsite. (3) To augment, you can also use the Fitting End Size Chart in the Appendix of the Industrial Tube Fittings, Adapters, and Tube Fabrication Equipment Catalog 4300 which shows tube fittings and adapter end profiles. This should be used loosely to gage the size of your fitting but is not the most accurate.

I don’t understand the Parker tube fitting and adapter part numbers; is there a breakdown/explanation?
To better understand the nomenclature of our tube fittings and adapters, you can review the How to Order pages in the General Technical section of our Industrial Tube Fittings, Adapters and Tube Fabrication Equipment Catalog 4300. These pages break the part numbers down into sections which will help you decode what each number and letter in the part number means.

I know my fitting end connection types; how do I determine Parker’s corresponding part number? How to configure a tube fitting or adapter?

  •  You can configure a part number on parker.com by drilling down to the part series type, then selecting your criteria (shape, end types and sizes, material, etc).
  •  You can also use the Parker FittingFinder app to configure your part number.

Are all BSPP 60-degree cone fittings interchangeable?
No. There are some important differences to understand about the different BSPP 60-degree cone fittings, which are made of two main styles that conform to either BS 5200 or JIS B8363. Read our blog BSPP 60-degree Cone Fittings: Looks Can Be Deceiving which compares the two styles similarities and differences, as well as the interchangeability.

How do I know what fitting/adapter goes with which metric port? There are many choices of fittings/adapters with the same threads, how do I know which will mate correctly with my metric port?
Our blog post Metric Ports: Which Fitting Goes with Which Metric Port details how to determine what type of metric port you have and what metric fittings mate with those ports. It also discusses the sealing methods for each port so you and your team further can ensure a leak-free connection in your system.

Tube Fitting & Adapter System Leak Questions

My system has a leak. How do I determine where the source of the leak is, and what specifically is causing the leak to occur?
Identifying the true cause of your system leak is critical. Quick assumptions can often be made based on what is initially seen, however this could lead to the true issue causing the leak being missed, causing more system inefficiencies (and potential damage), downtime and loss of production, and potentially injuries. Knowing that finding the true cause and source of your leak is not always easy, our team of engineers has created several blog posts to help. These will walk you through in detail how to most accurately identify the location and true cause of the leak to ensure it gets fixed probably and doesn’t reoccur. As stated in our posts, it is imperative to use the correct safety measures when locating, troubleshooting and fixing your leaking connection. See our series of detailed troubleshooting leaks posts below. It may also be helpful to read our blog post 10 Things Not to Do When Your Hydraulic Fitting Leaks.

Tube Sizing, Temp., Routing & Clamping Questions

How do I size tube for my system? How does the size of my tube effect the system efficiency?
Systems with properly sized tube will perform efficiently and cost-effectively. Tube that is sized too small or too large will cause system issues that will affect system efficiency. Our blog post Sizing Tube to Maximize Hydraulic System Efficiency details considerations and calculations to use to ensure the correct tube size for your system.

Do you sell inch tubing?
No, we do not sell inch tube. Most of distributors do have sources for inch tube. Contact your local Parker distributor for information.

What is the minimum and maximum wall thickness recommendations for tube fittings and adapters?
Reference our recommended minimum and maximum tube wall thickness chart for tube fittings adapters. The table breaks down the size by inch and metric tube O.D., then by fitting type and tube material. This table is on our Tube Selection Example page in the General Technical section of our Industrial Tube Fittings, Adapters, and Tube Fabrication Equipment Catalog 4300.

What is the temperature rating for different materials of tube? What are the tube derating factors for temperature?
Both the temperature ratings for common tube materials and the tube rerating factors for temperature can be found on the Temperature pages of the General Technical section of our Industrial Tube Fittings, Adapters and Tube Fabrication Equipment catalog.

Are there recommendations for tube line routing?
Yes. We have created guidelines for proper tube line routing to help you ensure an efficient and leak-free system. Taking the time to consider effective and efficient tube line routing is an important up-front investment that will save time and money down the line. Our blog post Tube Routing Tips for Hydraulic, Pneumatic and Lubrication Systems details the guidelines you need, as the most logical routing is not always the correct routing.

Do I need to clamp the tube lines in my system? How do I determine how best to clamp the tube lines?
Yes, clamping your tube lines will ensure your system remains efficient, leak-free and easy to maintain. Properly clamping your tube lines will help with system vibration dampening, reducing system noise, and tube mounting. Each of these topics are discussed in our blog post Best Practices: Tube Line Clamping for Hydraulic, Pneumatic or Lubrication Systems. Also discussed is the recommended clamp spacing and layout for tube lines, as well as selecting a clamp system.

O-ring & Seal Questions

TUBE FITTINGS AND ADAPTER O-RING AND SEAL QUESTIONS
On tube fittings and adapters with O-rings or seals, what is your standard material?
The standard O-rings and seals on our tube fittings and adapters are a 90 durometer Nitrile (NBR) O-ring. These O-rings are well suited for most industrial hydraulic and pneumatic systems. They have high extrusion resistance making them suitable for high pressure static applications. The temperature rating for this compound is -30 degrees F to 250 degrees F.

Do you have higher temperature O-rings?
Yes, we do offer an optional higher temperature 90 durometer FKM (fluorocarbon) O-ring. It has a temperature rating of -15 degrees F to 400 degrees F.

How do I request high temperature fluorocarbon O-rings on the tube fittings and adapters?
Yes. By adding FKM at the end of our tube fitting and adapter part numbers. For example: 8 F5OX-S FKM

Do I need to lubricate the O-ring on my fitting prior to assembly?
As a rule of thumb, it does not hurt to lubricate the O-ring all the time. That said, for user convenience, we pre-apply lubrication to some of our O-rings. It’s important to note that customers do not need to lubricate tube side O-rings, such as the O-ring in the face seal of Seal-Lok ORFS fittings. It is recommended to lubricate port side O-rings, such as SAE ORB or ISO 6149 ports. This is because the port side O-rings normally experience a lot of rubbing during installation, and the mating ports can be of a variety of quality. Lubrication will help overcome those variations. You can also read Parker O-ring Division’s blog post How to Lubricate an O-Ring. Please note: that blog post and video is shared for content, but the product shown using the O-rings are not fittings. We feel that there is still some valuable content regardless.

The O-ring on my tube fitting or adapter is damaged. How do I determine what the cause was and how to fix it?
Parker O-ring Division (ORD) has several helpful blog posts focused on diagnosing a damaged O-ring. Some of the issues listed in the blog do not pertain to O-rings on tube fittings or adapters, but many do apply to issues you can see on your fittings and adapters. Below is a list of the blog posts that might be helpful to you:

  •  Diagnosing a Damaged O-ring
  •  Reduce Downtime and Costly Seal Replacements – Seal Failure Diagnosis Part 1
  •  Reduce Downtime and Costly Seal Replacements – Seal Failure Diagnosis Part 2

Do you have extreme temperature seals for your tube fittings and adapters?
Yes, we offer Seal-Lok Xtreme tube fittings and adapters which use the proven leak-free O-ring Face Seal design along with special metal face seals and metal port seals (when applicable). The sealing temperatures are -328 degrees F to 1,200 degrees F (-200 degrees C to 649 degrees C). Seal-Lok Xtreme tube fittings and adapters are suitable for LNG applications and extreme temperatures such as turbines.

How do I choose the proper O-ring material for my application?
There is an O-ring Material Selection guide in the General Technical section our Industrial Tube Fittings, Adapters and Equipment Catalog 4300. This guide will show different media types, temperature ranges, and recommendations.

Do you offer special shaped O-rings for non-tube fitting and adapter applications?
Yes, Parker's O-ring Division does offer many kinds of special O-rings. See their complete product offering here.
