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. 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.
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.
