Hex Plug Configuration
Male NPT Thread
Precision-machined male NPT threads allow the plug to install into compatible female threaded pipe openings, fittings, valves, manifolds, or equipment ports.
Cored Brass Body
The lead-free brass body uses a cored design to reduce material weight while maintaining dependable strength for compatible threaded piping applications.
External Hex Head
The hex-shaped head provides a positive wrenching surface for controlled installation, tightening, inspection, and removal.
Construction Details
The lead-free brass body provides corrosion resistance and dependable durability for compatible potable water and general-purpose piping systems.
Its cored internal design reduces material weight while preserving the fitting's overall threaded function and mechanical integrity.
Precision-machined male NPT threads help provide secure engagement with compatible female threads, while the external hex head allows straightforward installation and removal with an appropriately sized wrench.
Cored vs. Solid Hex Plug
Cored Hex Plug
- Reduced internal material
- Lower fitting weight
- Lead-free brass construction
- External hex wrenching surface
- Designed for sealing compatible female NPT ports
Solid Hex Plug
- Full-body solid construction
- Greater material mass
- Similar threaded sealing function
- External hex wrenching surface
- Selection depends on application requirements
NPT Threaded Connection
Male NPT
The tapered male NPT thread is designed to engage a compatible female NPT opening and tighten progressively as the plug is installed.
Thread Sealing
Use PTFE tape or an approved thread sealant compatible with the system media and piping materials to help provide a leak-resistant threaded connection.
Typical Applications
Water & Plumbing Systems
- Water distribution piping
- Residential plumbing
- Commercial plumbing

What material is this plug made from?
The plug is manufactured from lead-free brass.
What does cored mean?
A cored plug uses an internal cavity or reduced-material body design to lower weight while maintaining the threaded sealing function of the fitting.
What type of thread does this plug use?
It uses a male NPT threaded connection.
What is a hex head plug used for?
A hex head plug is used to close or seal an unused compatible female threaded pipe opening.
Why does the plug have a hex head?
The external hex head provides a wrenching surface for controlled installation, tightening, and removal.
Is this plug suitable for potable water?
The supplied product information identifies lead-free brass construction for compatible potable water and plumbing applications.
Are multiple sizes available?
Yes. These plugs are available in multiple nominal pipe sizes.
Should thread sealant be used?
Use PTFE tape or an approved thread sealant compatible with the system media and piping materials.
What is the difference between a cored plug and a solid plug?
A cored plug uses less internal material to reduce weight, while a solid plug uses a full-body construction. Both are intended to seal compatible threaded openings when properly selected and installed.
What should I verify before ordering?
Confirm the required nominal pipe size, female NPT thread, pressure, temperature, media compatibility, and lead-free requirements for the application.
