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.

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.

Universal-Thread Plated Brass Pipe Fittings
When you're unsure of the exact thread type you need, these fittings have universal threads that are compatible with the most common ones (NPT, NPTF, BSPP, BSPT). Made of nickel-plated brass, they resist corrosion better than plain brass fittings. A reusable Buna-N O-ring protects against leaks.
Connectors, adapters, and reducers all have a hex-shaped body, so you can tighten them with a wrench.
Fittings with intermittent swivel rotate 360° as needed to allow movement.
NPTF (Dryseal) threads are compatible with NPT threads.
