Standard-Wall Chrome-Plated Brass Threaded Pipe Nipples and Pipe
The polished chrome plating gives this brass pipe a bright, shiny appearance and provides extra corrosion resistance. Also known as Schedule 40 pipe, it is commonly used in low-pressure applications. Pipe is seamless so it has a smooth interior for unrestricted flow.
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. 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.
