A: Applying a thin coating of WD-40 or similar lubricant to the jaw before starting a job should help.
A: UL Listed provides approval by UL for field and factory installation. UL Recognized products limit products to being factory installed only.
A: Follow all of our steps on prep and installation.
A: Possibly, skipping the prep and installation steps causes the tube to leak
A: Your fingernail can feel a deep scratch. Try using a new piece of Scotch-Brite abrasive pad. Alternatively, use a 340 grit sandpaper/cloth
A: Use the depth gauge provided or the minimum insertion depth chart to determine the correct insertion depth. Mark the tubing with a permanent marker to indicate proper insertion depth on every tube. See Table 1 below.

A: No, we do not have a specific product designed to crimp over the swaged tubing. However, if there are at least 2 inches of straight copper tubing after the flared end and is accessible with the jaws, you may cut the flared end off and crimp directly to the tube.
A: Crimp with the jaw straddling directly over the O-ring section of the fitting
A: Tool dependent; consult the tool manufacturers owner’s manual.
A: Tool dependent; consult the tool manufactures owner’s manual.
A: ZoomLock MAX jaws are laser hardened and have a finite life expectancy. We encourage each customer to have the jaws and tools serviced and checked annually or every 10,000 crimps depending on which comes first.
A: Please refer to page 18 for the press tool compatibility table.
A: Check jaws at the latest 1 year after the purchase or after 10,000 pressings (according to which occurs first) by an authorized Rothenberger testing center and repeat these checks at the latest 1 year or another 10,000 pressings after the previous inspection. During jaw inspection, check the jaws for operating and functional safety and wear parts (e.g., springs). Functionally and operationally safe jaws are returned.
A: Tool dependent; check the tool manufacturer owner’s manual.
A: No, ZoomLock MAX is designed explicitly for copper to copper connections.
A: As follows;
A: Yes, ZoomLock MAX is a press fitting system for use with hard, half-hard, or annealed copper tube conforming to EN12735-1 or ASTM-B280.
A: The product has a 10-year guarantee from the first date of purchase. Please refer to full terms and conditions.
A: Hydrogenated Nitrile Butadiene Rubber (HNBR).
A: The expected life of the O-ring, if used within the product specifications for temperature and pressure, is at least 25 years. The product has a 10-year guarantee from the first date of purchase.
A: No, the product is not subject to degradation under normal storage conditions, provided it’s kept in original packaging and not exposed to direct sunlight for long periods.
A: ZoomLock MAX is approved for use with R-32, R-134a, R-404A, R-407C, R-407F, R-410A, R-507, R1234ze, R1234yf, R-718, R-450A, R-513A, R-448A, R-449A, R-407A, R-427A, R-438A, R-417A and R-422D. Please check our website www. ZoomLockMAX.com for updates on the ZoomLock MAX range.
A: Use ZoomLock MAX for approved POE, PAO, PVE, AB, and mineral oils. The O-ring has been tested successfully with PAG oil; however, do not use PAG oil with copper systems due to the potential for corrosion of the copper material.
A: No, if a pressed fitting is leaking, the fitting must be cut out and replaced. You should not attempt to braze the fitting as you may melt the O-ring material and thus introduce contaminants into the system that could cause other system issues.
A: No, ZoomLock MAX has been thoroughly freeze/thaw tested
A: No, ZoomLock MAX has been Acid Salt Spray tested to ASTM G85. As with all copper installations, avoid exposure to ammonia.
A: Yes, the O-ring does compensate for small/minor scratches on the surface of the tube. However, avoid imperfections adjacent to the crimp area such as scratches, incise marks, and tubing that is not round. Reference copper piping standard for roundness.
A: If you use ZoomLock MAX in an application that the fitting goes beyond the specified limits of the O-ring, then there is an increased likelihood that a leak can occur due to the compromised O-ring.
A: ZoomLock MAX fittings comply with the cleanliness standards as required in the following Copper Tube Standards EN 12735-1 and ASTM-B280. Keep the zip closure bag sealed to protect fittings from contamination.
A: Vibration is a recognized cause of leaks, design the system, and install to comply with all local standards and codes of practice, which aim to minimize vibration. Extensively tested ZoomLock MAX fittings ensure the joint doesn’t leak as a result of system vibration and complies with the following standards: ISO 14903, Temperature Pressure Cycling and Vibration Test; UL 109 - 8, Vibration Test; UL 207, Fatigue Shock Test.
A: Good installation practice, a nitrogen purge during any brazing (not required with ZoomLock MAX mechanical fittings), a deep evacuation, and the proper installation and use of filter-driers containing new and effective molecular sieve desiccants prevent many system failures including the buildup of acid within the system. When selecting which desiccant material is best for an application, consider water capacity, refrigerant and lubricant compatibility, acid capacity, and physical strength, which are essential characteristics of desiccants.
A: No, some rotational movement is quite acceptable, the joint won’t leak, nor will it come apart under the pressure loading and during system operation. Some joint movement is good and allows for expansion and contraction in the system pipework.
A: No, ZoomLock MAX is not suitable for medical gas applications.
A: No, only press ZoomLock MAX fittings once.
A: No, do not use ZoomLock MAX for drinking water systems.
A: No, use ZoomLock MAX for air conditioning and refrigeration applications only.
A: Pull 200 microns for a deep vacuum.
