Value Collection 13126 Malleable Iron Square Pipe Plug 1-1/2 in

Product Description

The VALUE COLLECTION 13126 is a 1-1/2 inch malleable iron square pipe plug used to seal open pipe ends in piping systems carrying liquid, gas, or steam. Rated at 300 psi for liquid and gas service and 150 psi for steam, this Class 150 fitting is galvanized for corrosion resistance. The square head drive allows installation with a standard wrench or socket. Plumbers, pipefitters, and mechanical contractors use this plug when capping off branch lines, test ports, or unused tapping points during system work or pressure testing.

This square plug is suited for residential and commercial plumbing, HVAC hydronic systems, and industrial piping applications where a threaded pipe end requires a secure, pressure-rated seal. The 1-1/2 inch fitting size is a common dimension found in main supply and return lines, manifold assemblies, and distribution headers. The galvanized finish provides an additional layer of protection in wet or corrosive environments.

Designed as an OEM-style replacement and standard fitting for 1-1/2 inch threaded malleable iron piping systems in liquid, gas, and low-pressure steam service.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable IPC and IFGC code requirements. Depressurize and isolate the pipe section before installing or removing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before seating the plug. Do not overtighten — use a wrench to achieve a firm, leak-free seal without stressing the fitting or pipe threads.
