Question by: Todd R on Aug 30, 2025, 8:25 AM
got a -12 A/C hose that needs spliced, is this the one with the low side charge port for R134a?
Answer by: Customer Support on Sep 1, 2025, 7:10 AM
For R134a A/C and refrigeration setups, this fitting is a -12 hose splicer that includes a low side charge port. Both ends are 0.75 inch, with a barb on one side and a line, hose, tube style end on the other, and it uses two clips per fitting as part of the E-Z Clip system.
Question by: Daryl E on Apr 15, 2025, 9:11 AM
Will this thing work with R134a refrigerant, or do I need a different fitting?
Answer by: Customer Support on Apr 17, 2025, 7:34 AM
This splicer is indeed compatible with R134a refrigerants.
Question by: Neil M on Oct 21, 2025, 3:27 PM
What all do I need on hand before I start putting this splicer together? Don't want to get halfway through and realize I'm missing something.
Answer by: Customer Support on Oct 23, 2025, 12:05 PM
Before you start, round up the FT1357 Clip Closing Pliers and a guillotine blade or equivalent cutting tool. You'll also need two appropriately sized clips and a cage, refrigerant oil that's compatible with your A/C or refrigeration system, and GH134 Multi-Refrigerant hose. The nipple assembly comes with two black o-rings already on it, and those should stay put, don't remove or replace them. Once you've got all that together, the process moves pretty quick.
