The RLS 3051140800111 is a reducer press fitting designed to transition between 7/8-inch and 1/2-inch tubing in refrigerant or fluid piping systems. Press fittings eliminate the need for open-flame brazing, allowing technicians to make secure, leak-tested connections using a press tool. This fitting is sized for copper or compatible tubing and is installed by licensed HVAC or refrigeration technicians during system assembly, repair, or retrofit work.
This reducer fitting is suited for residential and light commercial HVAC and refrigeration applications where a tubing size change is required in a refrigerant line or hydronic circuit. It is particularly useful in retrofit scenarios where no-flame connection methods are required by code or site conditions. The 7/8-inch by 1/2-inch sizing covers a common transition point found in split system refrigerant piping.
Designed as an OEM-style press fitting replacement for HVAC and refrigeration systems requiring a 7/8-inch to 1/2-inch tubing reduction.
Installation should be performed by a licensed HVAC or refrigeration technician using a compatible press tool rated for the fitting size. Recover all refrigerant and depressurize the system fully before cutting into any refrigerant line. Ensure tubing ends are cut square, deburred, and fully seated in the fitting before pressing. Follow applicable mechanical codes and the press tool manufacturer's guidelines for proper jaw selection and press cycle confirmation.
