ZoomLock PUSH fittings come in two varieties: removable and optimized. The removable style has a plastic lip, allowing it to be removed even after installation with a proper tool, and has an O-ring that is compatible with R-22. PUSH fittings can withstand up to 870 PSI, meaning that leaks are most likely caused by improper installation rather than the fittings themselves.

ZoomLock MAX fittings are rated to withstand 700 PSI. The tool and jaw provide three points of pressure before, after, and on the O-ring, giving you a leak-free seal every time.

For best results, clean the copper tubing before adding the ZoomLock fitting, preferably with Scotch-Brite. You’ll also want to check for ridges on the copper, which may create leak points for the refrigerant. It’s also best to use a depth gauge and mark the tubing with a Sharpie. Then, you just push on the fitting until it clicks. Then, you align the O-ring with your pressing tool and press it to make a leak-free seal.

ZoomLock also has pre-made flare fitting options available; these can especially come in handy on ductless installations.
