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.
Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.
Universal threads have a Buna-N rubber gasket to protect against leaks.
