How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

High-Pressure Plated Brass Threaded Pipe Fittings

The plating on these brass fittings creates a shiny finish and provides extra protection in corrosive environments. Fittings have the strength to handle high-pressure applications.

Nickel-plated brass fittings provide better corrosion resistance than unplated brass fittings. Black zinc-plated brass fittings have a shiny finish that offers better corrosion resistance than nickel-plated brass and stands up to salt spray applications. Chrome-plated brass fittings have a mirror-like finish and provide better corrosion resistance than nickel- and black zinc-plated brass.

NPTF (Dryseal) threads are compatible with NPT threads.
