E-Z Clip Series Aluminum Lifesaver Kit, 0.71 Inch Tube OD, -12 Hose, Straight

Everything needed for a complete straight fitting assembly is included: the nipple assembly with its two black o-rings, properly sized clips, a cage, and the GH134 multi-refrigerant hose. You will also need a clip closing plier (FT1357) and a guillotine blade (FT1356) or a comparable square-cutting tool, along with refrigeration or A/C compressor oil for lubricating the nipple before insertion. That oil has to come from your system's existing refrigerant oil supply since it needs to be compatible with whatever refrigerant you're running. Nothing else is required beyond those items to complete the assembly.

Fit comes down to two callouts on this kit: it is for 0.71 inch tube OD and it is set up for -12 hose, in a straight configuration. If those are the sizes you are working with, this Lifesaver Kit matches that combination.
