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.
Female x male 90° elbow adapters are also known as street elbows. Right-angle tee adapters are also known as run tees.
NPTF (Dryseal) threads are compatible with NPT threads.

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.
