Value Collection G342 80 Pipe Union 3 Inch Malleable Iron

Product Description

The VALUE COLLECTION G342 80 is a 3-inch galvanized malleable iron pipe union designed for threaded-end piping systems in liquid, gas, and steam service. Rated at 300 psi for liquid and gas applications and 150 psi for steam, this Class 150 union provides a reliable, leak-resistant connection point that allows piping sections to be disconnected without disturbing adjacent fittings. It is installed by licensed plumbers and pipefitters in commercial and industrial piping runs where frequent service access or equipment isolation is required. The galvanized finish offers corrosion resistance in moderately aggressive environments.

This union is suited for residential and light commercial plumbing, HVAC piping, and gas distribution systems where a standard threaded union connection is specified. The 3-inch size accommodates larger-diameter runs common in mechanical rooms, boiler piping, and main gas supply lines. Its Class 150 rating aligns with standard schedule piping used across a wide range of building mechanical systems. Threaded ends comply with common NPT thread standards, making installation straightforward with standard pipe wrenches and thread sealant.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) where relevant. Shut off and depressurize the line completely before disassembling or installing any union fitting. Use appropriate thread sealant or PTFE tape rated for the service medium, and inspect threads for damage before assembly. Tighten to hand-tight plus additional turns as required to achieve a leak-free seal without over-stressing the fitting body.
