Value Collection 458-002NL Brass Pipe Plug 3/8 Inch Mpt

Product Description

The VALUE COLLECTION 458-002NL is a red brass pipe plug designed to seal threaded pipe openings in plumbing, HVAC, and industrial piping systems. It features male pipe thread (MPT) ends and carries a Class 125 pressure rating of 125 psi, making it suitable for low- to medium-pressure applications. The red brass construction offers good corrosion resistance in water service and general-purpose piping. This plug is a standard off-the-shelf fitting used by plumbers, pipefitters, and HVAC technicians to cap open pipe ends during installation, testing, or system modification.

This fitting is used in residential and light commercial piping systems where a threaded pipe end requires a secure, pressure-rated seal. Common applications include capping unused ports on manifolds, isolating branch lines, and blanking off test points in water supply, hydronic heating, and compressed air piping. Its 3/8 inch MPT thread size fits standard schedule 40 and schedule 80 threaded fittings of the same nominal size.

Key Features

• Red brass construction provides corrosion resistance in water and general-purpose piping service

• Class 125 rated to 125 psi working pressure
• Compact form factor suits tight spaces in manifold and valve bodies
• Single-piece solid plug design with no moving parts or seals to fail

Compatibility

Designed as a standard threaded pipe plug for use with 3/8 inch female NPT (FNPT) threaded fittings, valves, manifolds, and equipment ports rated for Class 125 or lower service.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC and local plumbing code requirements. Shut off and depressurize the piping system before installing or removing any threaded fitting. Apply thread sealant tape or pipe dope to the male threads before engagement to ensure a leak-free seal. Do not overtighten brass fittings, as the material is softer than steel and threads can be damaged by excessive torque.
