Williams Comfort Products 8FG38MF Gauge Fitting Nptf

Product Description

The WILLIAMS COMFORT PRODUCTS 8FG38MF is a 1/4-inch NPTF gauge fitting designed for use in heating appliance service and gas pressure testing applications. This fitting provides a secure, leak-resistant connection point for attaching pressure gauges to gas-fired equipment. The NPTF thread form creates a pressure-tight mechanical seal without relying solely on thread sealant, making it a reliable choice for service technicians working on natural gas or propane heating systems. It is typically installed by licensed HVAC technicians and gas appliance service professionals during routine system diagnostics or commissioning.

This gauge fitting is suited for residential and light commercial heating equipment service. It is commonly used when performing gas pressure checks on furnaces, wall heaters, and other gas-fired appliances that require a 1/4-inch NPTF port for gauge attachment. The compact, single-piece design allows for straightforward installation in tight service locations where access may be limited.
