Kit Contents & Core Function: This set provides 2 quick couplers (1 red, 1 blue) designed as an R1234yf to R134a adapter. It allows you to connect your existing R134a service equipment to vehicles that use the newer R1234yf refrigerant, facilitating tasks like evacuation, recovery, and recharge without needing a full new toolset
Precise Size & Color-Coded Design: The adapters match standard port sizes: the blue low-pressure adapter fits 14mm female ports, and the red high-pressure adapter fits 17mm female ports. This color-coding follows industry convention for instant identification, helping to prevent connection errors during AC service under the hood
Sealed Connection to Prevent Leaks: Featuring an internal ball-lock and rubber seal, this 1234yf adapter aims to create a secure, leak-resistant connection at the coupling point. This design works to help contain the R1234yf refrigerant within the system during service, which is important for both efficiency and cost
Brass Construction: Machined from brass, these couplers are made for the demands of AC work. The material is commonly used for its favorable properties in such applications. The knurled grip is designed for a positive hold, aiming to make connections and disconnections more straightforward
Broad Compatibility with Service Tools: This adapter set is made to work with standard R134a manifold gauge set equipment, including vacuum pumps and recovery machines. It integrates into your existing workflow for R1234yf refrigerant recharge and diagnostics, aiming to offer a practical solution for servicing newer vehicle AC systems
