Value Brand 1-1/4" Brass Plug MNPT 200 psi 400°F

SKU CH-BYJW-YDZ8E

1-1/4 inch brass pipe plug rated 200 psi and 400°F for hot water lines

  • 200 psi rating handles demanding pressure systems
  • 400 °F tolerance suits high-temperature applications
  • Brass construction resists corrosion in wet environments
  • 1-1/4 inch MNPT threads fit standard pipe fittings
  • Class 125 rating confirms reliable performance standards

Brass Pipe Plug

This 1-1/4 inch brass plug seals threaded pipe ends in residential and light commercial plumbing systems. It carries a Class 125 rating and a 200 psi maximum operating pressure. The fitting suits installers who need a reliable closure for water, air or inert gas lines.

Thread Sealant Not Included

The plug arrives without pre-applied thread sealant or a supplied seal so the installer chooses the tape or compound that matches the system fluid. This flexibility avoids compatibility issues with potable water or chemical lines. California Proposition 65 warnings apply because the brass contains listed chemicals.

400 Degree Temperature Limit

Continuous service up to 400 degrees Fahrenheit defines the upper thermal boundary for steam or hot water loops. Systems that exceed this temperature require a different alloy or pressure class. The lower limit of minus 20 degrees Fahrenheit covers typical outdoor exposure.

Questions about this item

How often should the thread sealant on the 1-1/4" MNPT brass plug be inspected or replaced under normal service?

The plug ships without pre-applied thread sealant, so any sealant you apply during installation should be checked whenever the joint is disturbed or if leakage appears at the 200 psi rating.

What is the first limit reached when the plug operates continuously at its 400°F temperature rating?

The 400°F upper temperature limit of the brass body and Class 125 rating defines the maximum sustained thermal envelope before material degradation accelerates.

Does the brass plug generate noticeable heat or noise when pressurised to 200 psi in a closed-loop system all day?

As a static threaded plug with no moving parts, it produces no operational noise and negligible heat beyond the fluid temperature already present in the line.
