Frequently Asked Questions
Q: What does this R12 to R134A conversion kit do?
A: This conversion kit allows you to retrofit an older R12 refrigerant charging port so it can accept modern R134a quick-disconnect couplers. It includes both high-side and low-side adapters with standard 1/4 SAE fittings, making it straightforward to upgrade classic vehicle A/C systems to work with today's R134a refrigerant charging equipment.
Q: Is this kit compatible with my vehicle?
A: This kit is designed for universal fitment on vehicles that originally used R12 refrigerant charging ports. Both the high-side and low-side connections use standard 1/4 SAE sizing, which is widely compatible. If your vehicle's A/C system originally used R12 refrigerant, this retrofit coupler set should fit your application.
Q: What is included in the package?
A: The package includes four pieces: one blue low-side quick disconnect coupler, one red high-side quick disconnect coupler, one blue cap, and one red cap. The color-coded design helps you quickly identify which coupler connects to which port on your A/C system.
Q: Are the couplers color-coded for a reason?
