Williams Comfort Products 8RH38DF High Flow Coupler

Product Description

The WILLIAMS COMFORT PRODUCTS 8RH38DF is a 3/8 inch NPTF female high flow coupler designed for use in fluid and gas line connections where a reliable, leak-resistant threaded coupling is required. The NPTF (National Pipe Taper Fuel) thread form creates a pressure-tight mechanical seal without relying solely on thread sealant, making it a dependable choice for demanding service applications. Weighing 0.701 pounds, this coupler is a single-unit component suited for professional installation in plumbing, HVAC, and related trade environments.

This coupler is appropriate for use in residential and light commercial systems where 3/8 inch female NPTF threaded connections are specified. It is commonly installed in gas or fluid supply lines, manifold assemblies, and equipment hookups that require a high flow passage to minimize pressure drop across the fitting. Licensed plumbers and HVAC technicians are the typical installers of this type of component.

Key Features

• 3/8 inch NPTF female thread provides a pressure-tight mechanical seal

Compatibility

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local codes and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) where relevant. Shut off the gas or fluid supply and relieve system pressure completely before removing or installing any coupler. Apply thread sealant or tape rated for the specific service medium to the male threads before making the connection. Do not overtighten — use a calibrated torque wrench appropriate to the fitting size and material to avoid thread damage.
