Dorman Brass Pipe Plug Square Head

The Dorman brass pipe plug with a square head is a threaded fitting. It seals off a tapped port, pipe opening or fitting in a fluid system. These plugs are also called square head pipe plugs or brass NPT plugs. They are a common choice for plugging ports in automotive, marine, RV and general equipment plumbing.

Key Features:

• Brass construction resists corrosion and works well in many fluid applications.
• Square head lets you tighten and remove the plug with a wrench or socket.
• Male tapered pipe thread (MNPT) makes a tight seal in a matching female NPT port.
• Seals unused ports, drain openings and test ports.

For the best seal, use a thread sealant or PTFE tape that suits the fluid in your system. Tighten the plug snugly without overtightening, which can damage the threads or the port.
