Value Collection 13141G 1/2 Inch Malleable Iron Pipe Union

Product Description

The VALUE COLLECTION 13141G 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. This union allows technicians to separate piping runs without cutting pipe, making it a standard component in maintenance-friendly installations. Rated at 300 psi for liquid and gas service and 150 psi for steam, it meets the demands of most residential and light commercial plumbing and mechanical systems. A galvanized finish provides corrosion resistance in damp or outdoor-adjacent environments. Plumbers, pipefitters, and HVAC mechanics install this fitting as part of threaded iron pipe assemblies.

This union is suited for use in gas distribution piping, hydronic heating systems, steam distribution, compressed air lines, and general plumbing applications where a threaded 1/2 inch iron pipe connection is required. Its Class 150 rating makes it appropriate for low-to-medium pressure service in residential and light commercial mechanical rooms, boiler rooms, and utility spaces. Installers working with Schedule 40 iron pipe in NPT-threaded configurations will find this a straightforward replacement or new-installation fitting.

Key Features

• 300 psi liquid and gas pressure rating for reliable service in pressurized pipe systems
• 150 psi steam pressure rating suitable for low-pressure steam applications
• Malleable iron construction provides strength and machinability for threaded connections
• Galvanized finish resists corrosion in wet or humid environments
• Class 150 rated fitting compatible with standard iron pipe service conditions
• 1/2 inch fitting size fits common residential and light commercial pipe runs

Compatibility

Designed as an OEM-style replacement or new-installation union for 1/2 inch NPT threaded malleable iron pipe systems in plumbing, HVAC, and steam applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and IFGC codes. Shut off all fluid or gas supply and depressurize the system completely before disassembling existing piping or installing this union. Use an appropriate thread sealant or PTFE tape rated for the service medium — confirm sealant compatibility with gas service if used in fuel gas piping. Do not overtighten the union nut; hand-snug plus wrench tightening to achieve a leak-free seal is standard practice for malleable iron threaded fittings.
