Value Collection 420T30 Malleable Iron Pipe Coupling 3 in

Product Description

The VALUE COLLECTION 420T30 is a Class 150 malleable iron pipe coupling designed for threaded pipe connections in liquid, gas, and steam service. Sized at 3 inches with National Pipe Standard (NPS) threading, it carries a pressure rating of 300 psi for liquid and gas service and 150 psi for steam service. The galvanized finish provides corrosion resistance for use in exposed or moderately harsh environments. Plumbers, pipefitters, and mechanical contractors install this fitting as a standard inline connection to join sections of threaded iron pipe in commercial and industrial piping systems. It meets ASTM standards for malleable iron fittings.

This coupling is suited for residential and commercial plumbing, HVAC hydronic piping, fire protection auxiliary lines, and general industrial pipe systems where a durable, threaded inline connection is required. Its 3-inch fitting size fits standard schedule pipe in that diameter. The galvanized malleable iron construction makes it appropriate for gas distribution piping, water supply lines, and low-pressure steam heating systems where a reliable mechanical joint is needed.

Key Features

• 300 psi pressure rating for liquid and gas service
• 150 psi pressure rating for steam service
• NPS threaded end connections for standard pipe compatibility
• Galvanized finish for corrosion resistance in exposed installations
• 3-inch fitting size for inline pipe joining on larger-diameter runs

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3-inch NPS threaded malleable iron pipe systems in liquid, gas, and low-pressure steam applications.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes. Shut off and depressurize the pipe system completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to NPS threads before assembly to ensure a leak-free joint. Do not exceed the rated pressure limits for the intended service type.
