Value Collection B-PLG20 Black Square Plug 2 in Malleable Iron

Product Description

The VALUE COLLECTION B-PLG20 is a 2-inch black malleable iron square plug designed to seal threaded pipe openings in low- to medium-pressure piping systems. Built to Class 150 standards, this plug carries a liquid and gas pressure rating of 300 psi, making it suitable for use in both liquid and gas distribution lines. The square head profile provides secure wrench engagement during installation and removal. The black finish is applied to malleable iron, offering durability in standard plumbing, mechanical, and light industrial applications. Installed by licensed plumbers and pipefitters, this plug is a reliable choice for capping unused threaded outlets.

This plug is used in residential and commercial plumbing, gas distribution, and mechanical piping systems where a threaded outlet needs to be capped or temporarily sealed. It fits standard 2-inch NPT threaded pipe connections. Common applications include capping branch outlets on gas lines, water supply systems, and compressed air distribution lines. The square drive head is accessible with standard pipe wrenches or adjustable wrenches, making it practical for tight installations in mechanical rooms, utility spaces, and crawlspaces.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC) where applicable. Shut off the gas or water supply and depressurize the line completely before installing or removing any threaded plug. Apply thread sealant tape or pipe compound appropriate for the service medium to the male threads before installation. Do not overtighten, as malleable iron threads can crack under excessive torque.
