Value Collection 4SQ1 Square Head Pipe Plug 1 in 304 Ss

Product Description

The VALUE COLLECTION 4SQ1 is a 1-inch square head pipe plug manufactured from 304 stainless steel for use in threaded piping systems. It features a male NPT (MNPT) end connection and a 150 psi pressure rating, making it suitable for sealing pipe ends in low- to moderate-pressure applications. The square head drive profile allows standard wrench engagement for reliable torque application during installation or removal. This plug is a standard plumbing and industrial fitting installed by plumbers, pipefitters, and mechanical contractors working on fluid handling and process piping systems.

This fitting is appropriate for residential and light commercial plumbing, HVAC hydronic systems, and general industrial piping where a corrosion-resistant stainless steel plug is required. The 304 stainless steel construction provides good resistance to rust and mild corrosion, making it a common choice for water, air, and compatible fluid lines. It is sold individually but requires a minimum order quantity of 2 units per transaction.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. De-pressurize and drain the line before installing or removing any threaded pipe plug. Apply appropriate thread sealant or PTFE tape to the male threads per local plumbing code requirements. Do not overtighten; use a properly sized wrench on the square head to avoid damage to the fitting or mating pipe threads.
