"Size 4 Oil Trap"

The 1/2″ Outer Diameter (12.70mm) copper P-trap is a high-precision ACR (Air Conditioning and Refrigeration) component specifically designed for small-diameter suction lines and specialized refrigeration equipment. Manufactured from C12200 dehydrated seamless copper, this trap is a critical “oil management” tool. It is engineered to catch and facilitate the return of compressor oil in vertical suction risers, preventing oil starvation and ensuring the long-term mechanical health of smaller compressors.
