Tectran Brass Square Head Pipe Plug NPT

The Tectran brass square head pipe plug (also called a square head plug or NPT pipe plug) closes off the end of a threaded port, pipe or fitting. It is made for heavy-duty tractor, trailer and air brake plumbing. Tectran has designed and manufactured tractor and trailer connection systems since 1972.

Key Features:

• Brass construction resists corrosion and holds up in demanding service.
• Square head design gives a firm wrench grip for installing and removing the plug.
• NPT (National Pipe Taper) male threads thread into a female NPT port and seal as they tighten.
• Universal, general-purpose plug for capping unused ports and air line fittings on air brake and other pneumatic systems.
• Multiple thread sizes are available as separate part numbers in this product line.

Use these plugs to terminate a line, cap off an unused port or seal a fitting during service. The product line suits fleet maintenance, trailer repair and general plumbing needs. Choose the individual part number that matches your thread size.
