3/8" Red Brass MNPT Plug

This 3/8 inch nominal pipe size plug is made from red brass and carries a Class 125 rating. It is intended for threaded piping systems where a solid closure is required. The component suits residential, commercial or light industrial installations needing a dependable seal.

Sustained pressure and temperature performance

The plug withstands a maximum operating pressure of 200 psi and operates continuously from -20 degrees to 400 degrees Fahrenheit. Red brass construction resists dezincification and corrosion during long-term exposure to water or steam. No pre-applied thread sealant is included so installers can select a compatible compound.

Class 125 pressure rating decides fit

The Class 125 designation defines the pressure envelope for which this plug is manufactured. Systems rated above this class need a higher-rated fitting. Buyers who need a larger nominal pipe size or a different thread standard cannot use this part.

Questions about this item

Will the brass plug withstand continuous 200 psi pressure at 400 °F?

The plug is rated for 200 psi maximum operating pressure and a temperature range of -20 °F to 400 °F, so it is designed for continuous service at those limits.

Which thread sealant or tape is required for the 3/8" MNPT connection?

The plug comes without pre-applied sealant or an included seal; apply PTFE tape or pipe dope compatible with brass and the system fluid before installation.

Can this Class 125 brass plug be used with existing steel or copper piping?

The 3/8" MNPT threads mate with standard NPT female fittings on steel, copper or brass pipe, and the red brass construction resists dezincification in mixed-metal systems.
