Value Collection G-PLG20 Malleable Iron Square Pipe Plug 2 in

Product Description

The VALUE COLLECTION G-PLG20 is a 2-inch malleable iron square pipe plug rated for liquid and gas service up to 300 psi and steam service up to 150 psi. It is a Class 150 fitting with a galvanized finish coating, providing corrosion resistance in wet or exposed piping environments. Square-head plugs are used to close off open pipe ends in threaded pipe systems. This fitting is installed by licensed plumbers and pipefitters working on gas distribution lines, water supply systems, steam lines, and general industrial piping. The galvanized malleable iron construction gives it adequate ductility for field threading and torquing without cracking.

This plug is suited for residential and light commercial plumbing and gas piping applications where a threaded closure is needed on a 2-inch NPT pipe end. Common install scenarios include capping unused branch tees on gas manifolds, sealing hydrostatic test ports, and closing off supply lines during system modifications. Its Class 150 rating aligns with standard low-pressure pipe fittings used throughout residential and commercial mechanical systems.

Key Features

• Malleable iron construction allows controlled deformation under stress without fracture
• Galvanized finish coating provides corrosion resistance in damp or outdoor-exposed applications
• 300 psi liquid and gas pressure rating for standard low-pressure service
• 150 psi steam pressure rating for low-pressure steam piping
• Class 150 fitting — compatible with standard Class 150 threaded malleable iron pipe systems
• Square head profile accepts a pipe wrench or adjustable wrench for secure installation and removal

Compatibility

Designed as an OEM-style replacement or standard fitting for 2-inch NPT threaded malleable iron pipe systems rated at Class 150.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with the applicable plumbing or mechanical code, such as the IPC or IFGC. Depressurize and isolate the pipe system completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before installation to ensure a leak-free seal. Do not over-torque malleable iron fittings, as excessive force can crack the fitting or damage threads.
