Brass Fittings Hex Head Plug

The Brass Fittings Hex Head Plug line offers brass hex head pipe plugs, also called hex head pipe plugs or NPT plugs. They seal the open end of a threaded port or pipe fitting. Typical uses include plumbing, air, water, fuel and fluid lines, and they also suit marine and general equipment applications.

Key Features:

• Solid brass construction resists corrosion and holds up well in everyday use
• Hex head design gives a firm wrench grip for installing and removing the plug
• Male NPT (National Pipe Taper) threads form a tapered seal with matching female NPT ports
• Simple, reliable way to cap, block off or plug unused ports and fittings

For the best seal, use a suitable thread sealant or PTFE tape on the threads. Tighten with a wrench until snug, and avoid overtightening. Choose the variant whose thread size matches your port.
