E-Z Clip Series Fitting, 7/8-14 Female O-Ring (Short Pilot), -12 Hose, 90 deg Elbow

Short pilot just means the o-ring boss thread engagement area is slightly shorter than a full-length pilot version. For most standard SAE O-Ring Face Seal ports, it functions the same way in terms of sealing, but the shorter pilot can make installation easier in tight spaces where a longer pilot would be awkward to start threading. The o-ring on that end handles the actual seal, so pilot length is more about physical clearance and ease of engagement than sealing performance.

It matches a 7/8-14 female O-ring seal (ORS) port with a short pilot, and it’s made for -12 hose in a 90 degree elbow configuration.

It needs Aeroquip GH134 Multi-Refrigerant hose. Using other hoses might cause leaks or be unsafe.

It matches a -12 hose E-Z Clip nipple assembly with a 90 degree elbow and a 7/8-14 female O-ring (short pilot) connection. It also calls out a 1.89 inch drop dimension, so the elbow offset is built around that geometry.

You'll need the FT1357 Clip Closing Pliers specifically for this. Regular pliers won't position squarely on the clip connection points the way that tool does, and staying square during the close is what makes the connection reliable. The pliers need to sit flush on those contact points and hold that position all the way through. Using a substitute risks an uneven close, which can compromise the whole assembly.

Yes, this E-Z Clip series fitting is indeed designed for use with a -12 hose.
