Value Collection G-UNI10 Malleable Iron Pipe Union 1 in

Product Description

The VALUE COLLECTION G-UNI10 is a Class 150 malleable iron pipe union designed for threaded piping systems in plumbing, mechanical, and light industrial applications. Rated at 300 psi for liquid and gas service and 150 psi for steam, this 1-inch union allows sections of threaded pipe to be connected or disconnected without rotating the pipe itself. The galvanized finish provides corrosion resistance for use in both indoor and moderate-exposure environments. Plumbers and pipefitters install this fitting where future serviceability or equipment removal is anticipated.

This union is suited for residential and commercial piping systems carrying water, gas, air, or steam within its rated pressure limits. Typical applications include boiler supply and return lines, gas appliance connections, compressed air distribution, and general plumbing rough-in work where unions are required by code or good practice at equipment connections. The 1-inch fitting size accommodates standard 1-inch NPT threaded pipe.

Key Features

• 300 psi liquid and gas pressure rating for reliable service in pressurized systems
• 150 psi steam pressure rating suitable for low-pressure steam piping
• Malleable iron construction provides strength and impact resistance vs. cast iron
• Galvanized finish for corrosion resistance in wet or humid environments
• Class 150 fitting for standard threaded pipe assembly
• Allows pipe disconnection without rotating adjacent pipe sections

Compatibility

Designed as an OEM-style replacement and standard-use fitting for 1-inch NPT threaded malleable iron piping systems rated to Class 150 service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes. Shut off and depressurize the system fully before disassembly or fitting installation. Apply appropriate thread sealant or PTFE tape to male threads before assembly; do not overtighten, as malleable iron threads can be damaged by excessive force. On gas applications, verify all joints with approved leak-detection solution after pressurization.
