FAQ - Frequently Asked Questions

Find answers to the most common Parflex product questions.

Where are Parker hoses made?

Parker hoses are made globally with more than 5 locations in North America.

Do I have to buy a full box of hose? Can I only buy the quantity I need?

A distributor may be able to break open a box. It depends on each stores policies. We do not break boxes.

What is the best hose crimper to order for a large range of hoses? Example: I have hoses ranging from 1/4” to 1”. Which unit do you recommend? Pneumatic or electric?

KarryKrimp 2. It crimps 2 wire braid hoses and 4 wire spiral hose up to 1-1/4" I.D. It also crimps 6 wire spiral hose up to 1" I.D.

What is the dash size of a hose in inches?

In hose sizes, the dash number denotes the hose size in sixteenths of an inch. A -12 after the part number calls out a 3/4" I.D. hose. To determine the inch size from the dash size, multiply the dash number by .062" and round up. (ie: 12 x .062 = .744" = .750")

Why do certain Parker Parflex hose series have a perforated cover?

When hose is used for gaseous applications a natural phenomenon referred to as permeation occurs. Since gas molecules are smaller in size when compared to liquids, the gas permeates through the tube wall and a path to atmosphere is required. The perforated cover allows this entrapped gas to pass through the hose cover and vent to atmosphere.

Can PTFE Hose be used for oil?

Yes, it is ideal for the transfer of oils in food processing. However, in industrial applications, it will work but there are less expensive alternatives designed for oil applications. Most thermoplastic hoses, such as 510D or 520N are ideal for oil applications and offer some additional benefits PTFE doesn’t have, like long continuous lengths and improved flexibility.

Which parflex hoses are used for pneumatic applications?

Any hose with perforated cover (520N, 528N, 527BA, 540P, 53DM, 55LT, 56DH, 580N, HLB02) or any of the PTFE hoses are suitable for pneumatics.

Can Parker Parflex repair failed hose?

With the exception of sewer hose and some of the Polyflex hose products, the answer is no. Many variables, such as pressure, temperature, routing, fluid media, length of service, etc. will alter the overall performance, efficiency, and life of the hose.

Why do I have to buy from a distributor?

One reason is because they sell the full Parker product line. Parker products are produced by different divisions and each divisions has an expertise. Ie. Hose, Tubing, etc.

Can you over crimp a hydraulic hose?

Yes. If that happens, the fitting must be cut off and a new fitting crimped on. Before crimping, you need to check the crimp instructions and after crimping, measure the crimp diameters as per the instructions in the catalog.

What is the hose replacement for:

510A	Replaced by 510D
510C	Replaced by 510D
518C	Replaced by 518D
540N	Replaced by 510D
560	Replaced by 560TJ
563	Replaced by 563TJ; 563LT
590	Replaced by 590TJ
HFSR	Replaced by D6R; 560TJ; 563TJ
D6R	Replaced by 563TJ
H6	Replaced by 563LT; 53DM
R6	Replaced by 563TJ; 563LT

Where do I go to find thermoplastic hose fitting models/drawings?

Visit the fitting series page and use the filters to find your fitting. Once you have the exact fitting, use the CAD tab to download images. You can also use the CAD Search on the main parker.com homepage.

How do you determine your fitting size? Example: 10356-8-6

Like hose sizes, the dash number denotes the fitting size in sixteenths of an inch. This -8 fitting describes a 1/2" end fitting with a 3/8" hose end. This is commonly referred to as a "jump size". A standard fitting would display the end fitting and the hose size the same. (ie: 10356-8-8) The only exception to this rule is the PAGE Series fittings for PTFE hose. In this series, the callout is reversed and the first number is the hose end and the second number is the end fitting.

What is the replacement for:

55 Series	Depending on the hose you are using, some fittings were placed by 56 Series fittings and others replaced by CG Series fittings. You can find most part number equivalents using Parkers Cross Reference Tool.
57 Series
58 Series
58H Series
51 Series	51R Series. These field-attachable fittings attach without a crimper and are used with 100R7 hoses 510D and 518D. You can find most part number equivalents using Parkers Cross Reference Tool.
54 Series	Rapid Assembly Fittings Parflex 56 Series Rapid Assembly Fittings speed up installations by up to 50%. You can find most part number equivalents using Parkers Cross Reference Tool.

Product Life: What is the life expectancy for Parker Parflex products?

Parker Parflex does not make recommendations for the life expectancy of any products, including hose, tubing, accessories, etc. The Parker Parflex catalog offers guidelines that define the specific performance limits of various Parker Parflex products. It is important to consider that every application is unique and that there are many variables that can potentially impact a product’s useful life expectancy. The end user is ultimately responsible for validating that the chosen product fulfills the demands of their specific applications. View the Parker Safety Guide

Where is the serial number located on my MiniKrimp™ machine?

The first place to look for the MiniKrimp™ serial number is the top surface of the Hardened Steel Sleeve (Part #015302) . No disassembly is required but you may need to remove the Die Ring and Die to read it. If your MiniKrimp™ machine was produced before January 2007 then the serial number is stamped and located on the bottom of the Hardened Steel Sleeve. In order to read it you must remove, from the bottom of the MiniKrimp™ machine, the Retention Ring (Part #822031), the Spring (Part #822012), and the Die Separator (Part #822011) in that order. For further reference, download Parflex 4660 Catalog and view the Tooling Section.

Where do I purchase Enerpac Replacement Oil used in the MiniKrimp™ machines?

Even though the Parflex Division does not provide Enerpac Replacement Oil as a product offering, Enerpac oil can be purchased directly from Enerpac Corporation (1-800-558-0530) or from Grainger (1-888-361-8649). The Enerpac part numbers are HF100 (1 quart container) and HF101 (1 gallon container). The Grainger part numbers are 3KD75 (1 quart container) and 3KD76 (1 gallon container).

What is the process to repair Enerpac components on MiniKrimp™ machines?

Parflex Division Quality Control has established a program with an Enerpac Service Center, A & A Hydraulics, to turn the MiniKrimp™ machines around in about five business days. The customer can also request to have the repaired machine drop shipped back to them from the Enerpac Service Center to shorten the turnaround time. A & A Hydraulics can be contacted at (216) 362-4000 for further information.

Where do I purchase replacement parts and components for my MiniKrimp™ machine?

If in need of repair parts, repair drawings, prints, part numbers, etc., contact Parflex Technical Services at (330) 296-2871 for assistance.
