2‑Piece 45° R32/R454B Brass Refrigerant Adapter

The Mtsooning 2‑piece 45° adapter set is engineered specifically for A2L refrigerants such as R‑32 and R‑454B. Its reverse‑thread safety design prevents accidental mating with incompatible systems, while the 1/4″ left‑hand female to right‑hand male flare fittings correct common thread mismatches between these refrigerants and standard HVAC hoses.

Designed for tight‑space installations, the 45° angled body reduces the need for additional pipe bends, improving sealing stability and overall system efficiency. Constructed from corrosion‑resistant brass, the adapter offers excellent pressure resistance and thermal conductivity, delivering reliable, leak‑proof performance during routine refrigeration maintenance.
