Williams Comfort Products 8RH38DM High Flow Coupler

Product Description

The WILLIAMS COMFORT PRODUCTS 8RH38DM is a male high flow coupler with a 0.375 inch NPTF thread connection. It is designed for use in gas supply lines and similar fluid or gas transfer applications where a secure, leak-resistant threaded coupling is required. The NPTF thread form creates a pressure-tight seal without relying solely on thread sealant, making it a reliable choice for gas and liquid service lines. HVAC technicians and plumbers typically install this fitting as part of a quick-connect or tool-style coupler assembly on service equipment or supply piping.

This coupler is suited for residential and light commercial applications where a high flow rate and a standard 0.375 inch NPTF male thread interface are required. It functions as a connection point between supply lines, hoses, or service tools that call for a male NPTF coupler at that thread size. It is sold individually and is appropriate for new installations or as a direct replacement fitting in existing assemblies.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber in accordance with applicable local codes and manufacturer guidelines. Shut off the gas or fluid supply and relieve any system pressure before removing or installing couplers. Use an appropriate thread sealant or tape rated for the service medium when making up NPTF threaded connections. Inspect the mating fitting threads for damage before assembly to ensure a proper seal.
