Value Brand

Value Brand 2 in Hex Plug 316 Stainless MNPT Class 150 37 mm

SKU CH-BKH7-1XQ9X

Closes pipe ends with a 2-inch MNPT hex head, 316 stainless steel rated 300 psi and 150 psi steam to ANSI B1.20.1 Class 150, 37 mm long

  • 316 stainless steel resists corrosion in demanding environments
  • 300 psi pressure rating handles high-pressure systems reliably
  • 150 psi steam rating supports steam-line applications
  • ANSI B1.20.1 compliance ensures thread compatibility and seal integrity
  • 37 mm overall length fits standard 2-inch piping installations

2-inch Hex Plug for Pipe Closure

This 316 stainless steel hex plug closes the end of a pipe or fitting using a male National Pipe Thread connection. The material delivers corrosion and temperature resistance within specified operating conditions. A hexagonal head enables wrench tightening to create a pressure-rated, leak-tight seal. It conforms to ANSI B1.20.1 standards for thread dimensions.

Hex Head Design and Class 150 Rating

The plug carries a Class 150 pressure classification with a maximum internal pressure rating of 300 psi and a steam pressure rating of 150 psi under specified conditions. Its overall length measures 37 mm, making it suitable for installations where space is defined by the piping layout. No pre-applied thread sealant or additional sealing components are included, so installers must apply their preferred sealing method.

Replaces Open Pipe Ends and Worn Plugs

This fitting upgrades from temporary caps, damaged plugs or open pipe ends that require a permanent, rated closure. The jump is worth it when a system demands documented pressure ratings and ANSI B1.20.1 thread conformance for inspection or code compliance. Buyers who need a larger nominal size, a female-threaded cap or an integrated sealing washer will not be served by this specific plug.

Questions about this item

What thread standard does the 2 in MNPT hex plug follow, and what pressure class does that standard cap it at?

It follows ANSI B1.20.1 and is classified Class 150, which caps the working pressure at 300 psi for general service and 150 psi for steam.

What wrench size and clearance does the 37 mm overall length require for installation?

The plug has a 2 in nominal pipe size with a hex head for wrench tightening; the 37 mm length means you need enough thread engagement depth plus head clearance to turn the wrench.

How do you install the 316 stainless plug without thread sealant, and what step is often missed?

Apply a compatible thread sealant or tape to the MNPT threads, then wrench-tighten the hex head until the joint is leak-tight; the step often missed is confirming the sealant is rated for 300 psi service.
