Value Collection 737004 1 in Malleable Iron Coupling Class 300

Product Description

The VALUE COLLECTION 737004 is a black-finish malleable iron pipe coupling designed for threaded pipe assemblies in industrial and commercial plumbing, gas distribution, and fluid handling systems. Rated to 1500 psi and classified as Class 300, this coupling provides a robust, pressure-capable connection for 1-inch threaded pipe runs. The black finish is standard for gas-service fittings and is compatible with black iron pipe systems. Licensed plumbers and pipefitters install this type of fitting during new construction, system modification, or repair work on pressurized gas and liquid lines.

This coupling is suited for residential and commercial applications where threaded malleable iron fittings are specified. Typical uses include natural gas supply lines, compressed air distribution, steam systems, and general industrial fluid piping. The 1-inch threaded end connections allow direct makeup with standard NPT-threaded pipe. This fitting ships in a package quantity of 5, making it practical for jobsite stocking or multi-point installations requiring several couplings of the same size.

Key Features

• Class 300 malleable iron construction rated to 1500 psi liquid and gas pressure

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-inch threaded black iron pipe systems in plumbing, gas, and industrial fluid distribution applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) as required by the application. Shut off and depressurize the line completely before disassembly or fitting makeup. Apply approved pipe thread sealant or PTFE tape rated for the service medium prior to threading the fitting onto the pipe. Pressure-test the completed assembly before returning the system to service.
