E-Z Clip Series Fitting, 7/8-14 Male Insert O-Ring, -10 Hose, Straight

Match three things: it is a straight E-Z Clip male insert fitting for -10 hose, the thread is 7/8-14, and the end type is SAE with a male insert O-ring seal. If your setup calls for a -10 A/C or refrigeration hose connection with 7/8-14 male threads and an O-ring seal, that lines up with this part.

This fitting is part of the Eaton Aeroquip E-Z Clip series, so it's designed to work specifically with GH134 Multi-Refrigerant hose and other components within that system. Mixing with other brands could lead to leaks or other problems.

You'll need a few things on hand before you start: FT1357 Clip Closing Pliers, a guillotine blade or equivalent cutting tool, two appropriately sized clips and a cage, GH134 Multi-Refrigerant hose, and refrigerant oil that's compatible with your A/C or refrigeration system. The oiling step is the one you really can't skip. Before you push the nipple into the hose, you have to coat it with a generous amount of compressor oil from your system. Skipping that makes insertion way harder and risks damaging the assembly. Also, the two black o-rings already on the nipple are a specific rubber compound and size. Leave them alone. Don't remove them, don't swap them out.
