Value Collection 737003 3/4 in Black Malleable Iron Coupling Class 300

Product Description

The VALUE COLLECTION 737003 is a 3/4-inch black malleable iron threaded coupling rated for Class 300 service at up to 1500 psi. It provides a straight, in-line connection between two threaded pipe sections and is used in gas, liquid, and industrial piping systems where a durable iron fitting is required. The black finish is standard for gas-line applications. Licensed plumbers, pipefitters, and gas service technicians are the primary installers of this fitting type.

This coupling is suited for residential and light commercial piping applications including natural gas distribution lines, compressed air systems, and general industrial fluid handling. The 3/4-inch threaded end connections make it compatible with standard NPT-threaded pipe of the same nominal size. It is sold in a package quantity of 5 units per order.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or gas service technician in accordance with applicable local codes, the International Fuel Gas Code (IFGC), and the International Plumbing Code (IPC). Always shut off the gas or fluid supply and relieve system pressure before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the intended service medium before assembly. Do not overtighten threaded connections, as malleable iron fittings can crack under excessive torque.
