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

Product Description

The VALUE COLLECTION 737003G is a 3/4-inch black malleable iron threaded coupling rated for Class 300 service. It is designed to join two sections of pipe with matching threaded ends in piping systems that carry liquids or gases under pressure up to 1500 psi. The black finish is standard for gas and industrial piping applications. This fitting is installed by licensed plumbers, pipefitters, and HVAC technicians working on commercial and industrial piping runs where high-pressure ratings are required.

This coupling is suited for use in residential and light commercial gas distribution lines, compressed air systems, steam systems, and industrial liquid piping where malleable iron fittings are specified. The 3/4-inch threaded end connections allow direct makeup with standard NPT pipe threads. It is a straightforward inline fitting used wherever a secure, pressure-rated pipe join is needed in ferrous piping systems.

Key Features

• Malleable iron construction for strength and durability in high-pressure piping
• Class 300 pressure rating supports up to 1500 psi service
• 3/4-inch threaded (NPT) end connections on both ends
• Black finish standard for gas and industrial piping applications
• Inline coupling design for joining two pipe sections of equal diameter

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4-inch NPT threaded malleable iron piping systems in gas, liquid, and compressed air service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC or IPC requirements. Shut off gas or fluid supply and depressurize the line completely before making or breaking any threaded connections. Apply an approved pipe thread sealant or PTFE tape to male threads before assembly. Do not overtighten; follow standard trade practice for malleable iron fittings to avoid cracking the fitting body.
