Product Description

The WILLIAMS COMFORT PRODUCTS 8R38DF is a 3/8 inch NPTF female regular speed coupler used in fluid and gas line connections across plumbing, HVAC, and related mechanical systems. This coupler provides a threaded female connection point compliant with NPTF standards, which creates a pressure-tight seal without requiring additional sealant in many applications. It is a compact, single-unit fitting suited for connecting supply lines, service hoses, or equipment ports where a fast, secure threaded coupling is required. Plumbers, HVAC technicians, and mechanical contractors typically install this type of fitting during system assembly or service work.

Regular speed coupler designs are commonly used in pneumatic, hydraulic, or refrigerant-adjacent service line connections. This fitting is sold individually and is suited for both new installation and replacement of worn or damaged couplers in existing systems.
