How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

High-Pressure Brass Threaded
Pipe Nipples and Pipe with Sealant
Not only does this pipe have the strength to handle high-pressure applications, the threads have a sealant applied for extra protection against leaks. Pipe is brass for good corrosion resistance.
Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.

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.
