Value Collection 13125D Malleable Iron Square Plug 1-1/4 in

Product Description

The VALUE COLLECTION 13125D is a malleable iron square plug fitting designed to close off open pipe ends in pressurized piping systems. Sized at 1-1/4 inches, it carries a pressure rating of 300 psi for liquid and gas service and 150 psi for steam service. The galvanized finish provides corrosion resistance suitable for a range of industrial and commercial plumbing environments. This Class 150 fitting is installed by licensed plumbers and pipefitters working on fluid, gas, and steam distribution systems where a secure, leak-free pipe termination is required.

This square plug is suited for use in residential and commercial piping applications involving water, gas, and low-pressure steam. It is commonly used to cap unused pipe outlets on distribution manifolds, branch lines, and test ports. The 1-1/4 inch fitting size fits standard NPT-threaded pipe of the same nominal diameter. Plumbers and mechanical contractors routinely keep this fitting on hand for service calls, retrofits, and new construction rough-in work.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code or International Fuel Gas Code. Shut off and depressurize the system completely before removing or installing any pipe plug. Apply an appropriate thread sealant or PTFE tape to the male threads before installation. Do not overtighten, as malleable iron fittings can crack if excessive force is applied.
