Value Collection 13141 Malleable Iron Pipe Union 1/2 in 5 Pack

Product Description

The VALUE COLLECTION 13141 is a Class 150 malleable iron pipe union sized at 1/2 inch, designed to create a disconnectable joint in threaded pipe systems carrying liquid, gas, or steam. The galvanized finish provides corrosion resistance for use in exposed or mildly corrosive environments. Rated at 300 psi for liquid and gas service and 150 psi for steam, this union meets the pressure demands of standard commercial and residential plumbing and piping installations. Licensed plumbers and pipefitters are the typical installers. This listing is sold as a pack of 5 units.

This union is suited for low-pressure steam, gas, and liquid piping applications across residential and light commercial settings. Common install scenarios include connecting sections of threaded black or galvanized iron pipe in mechanical rooms, boiler rooms, gas distribution lines, and process piping where periodic disassembly is required. The 1/2 inch fitting size is one of the most common sizes in residential and small commercial piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC and IFGC codes. Shut off and depressurize the pipe system completely before disassembling or installing any union fitting. Apply thread sealant or pipe tape appropriate to the service medium — confirm sealant compatibility with gas service before use on gas lines. Tighten the union nut by hand first, then use pipe wrenches to achieve a leak-free connection without over-stressing the fitting threads.
