John Guest PP451223W-US 3/8 Female Adapter Push-fit Nptf

Product Description

The JOHN GUEST PP451223W-US is a 3/8 inch by 3/8 inch female adapter fitting engineered for push-fit connections in potable water and pure water systems. Part of the John Guest PP Range of inch-size push-in fittings, it is molded from white polypropylene and fitted with EPDM seals. The 3/8 inch NPTF thread allows secure connection to standard female-threaded ports. Push-fit technology enables fast, tool-free connections and quick disconnections, reducing installation time on plumbing and water treatment systems. Polypropylene construction provides superior chemical resistance compared to acetal fittings, making this adapter a dependable choice for chemically demanding potable liquid applications.

This fitting is suited for residential and commercial plumbing, water filtration, and pure water distribution systems where food-quality-grade components are required. It is appropriate for cold water supply lines and water treatment equipment installations. Plumbers and water treatment technicians commonly specify this fitting where push-fit convenience and chemical resistance are priorities. Note that this fitting is not rated for compressed air or vacuum applications and should not be used in those service conditions.
