Value Collection 420S20 Malleable Iron Pipe Coupling 2 in

Product Description

The VALUE COLLECTION 420S20 is a Class 150 malleable iron pipe coupling designed for threaded pipe connections in plumbing, HVAC, and industrial piping systems. Sized at 2 inches with National Pipe Standard (NPS) threading, it handles liquid and gas service up to 300 psi and steam service up to 150 psi. The galvanized finish provides corrosion resistance in wet and exposed environments. Licensed plumbers and pipefitters install this fitting as a straight inline connector when joining two sections of threaded pipe in both new construction and retrofit applications. It meets ASTM standards for malleable iron fittings and is sold as a single unit.

This coupling is suited for residential and light commercial piping runs carrying water, gas, or steam. Typical applications include connecting threaded black or galvanized steel pipe in supply lines, gas distribution piping, and low-pressure steam systems. The 2-inch size is common in main distribution runs and branch headers where higher flow capacity is required. Installers working under IPC, IFGC, or local mechanical codes will find this fitting appropriate for a range of above-ground and accessible piping configurations.

Key Features

• Malleable iron construction with galvanized finish for corrosion resistance
• Rated to 300 psi for liquid and gas service
• Rated to 150 psi for steam service
• NPS threaded end connections for standard pipe compatibility
• Class 150 fitting meets ASTM standards
• 2-inch fitting size for main-line and header applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 2-inch NPS threaded steel pipe systems in plumbing, gas, and low-pressure steam applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC, IFGC, or local mechanical codes. Shut off and depressurize the line completely before disassembling any threaded connections. Apply an appropriate pipe thread sealant or PTFE tape rated for the service medium before threading the coupling onto the pipe. Hand-tighten first, then use a pipe wrench to achieve a proper seal without over-stressing the fitting.
