Value Collection MSC-62147970 Malleable Iron Pipe Union 1 in

Product Description

The VALUE COLLECTION MSC-62147970 is a 1-inch malleable iron pipe union rated for 300 psi liquid and gas service and 150 psi steam service. Malleable iron construction gives this Class 150 union the ductility and impact resistance needed for threaded piping systems in demanding mechanical and industrial environments. The galvanized finish coating provides corrosion protection suited to wet or outdoor-adjacent installations. Licensed plumbers and pipefitters install this fitting to join threaded pipe runs in a way that allows future disconnection without cutting or rethreading the line.

This union is appropriate for residential and light commercial plumbing, gas distribution piping, steam heating systems, and general-purpose fluid handling applications where a threaded, break-apart connection is required. The 1-inch fitting size fits standard NPT-threaded pipe of the same nominal diameter. It is commonly used in boiler rooms, mechanical rooms, and utility piping where future serviceability of downstream equipment is a priority.

Key Features

• 300 psi pressure rating for liquid and gas service
• 150 psi steam pressure rating
• Malleable iron construction for ductility and thread integrity
• Galvanized finish coating for corrosion resistance
• Class 150 fitting — standard for threaded iron pipe systems
• Allows line disconnection without cutting or rethreading

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-inch nominal NPT threaded iron pipe systems in liquid, gas, and steam service applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters working to IPC or IFGC requirements depending on the service medium. Shut off and depressurize the line and allow steam systems to cool fully before breaking any connection. Apply appropriate thread sealant or PTFE tape to all male threads before assembly. Do not overtighten the union nut, as malleable iron threads can crack under excessive torque.
