High-Pressure Plated Brass Threaded Pipe Nipples and Pipe

The plating on this pipe creates a shiny finish and provides extra protection in corrosive environments. It has the strength to handle high-pressure applications.

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

Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.

NPTF (Dryseal) threads are compatible with NPT threads.

Universal threads have a Buna-N rubber gasket to protect against leaks.
