Value Collection 735003G 3/4 Inch Malleable Iron Pipe Coupling

Product Description

The VALUE COLLECTION 735003G is a Class 150 malleable iron pipe coupling designed to join two sections of threaded pipe in plumbing, gas, and steam distribution systems. Rated at 300 psi for liquid and gas service and 150 psi for steam, this coupling handles the pressure demands common in commercial and residential mechanical systems. The malleable iron construction provides the toughness and thread integrity that licensed plumbers and pipefitters expect on the job. It installs using standard NPT threading and is appropriate for gas piping, water distribution, and low-pressure steam applications.

This coupling is suited for use in residential and light commercial installations where threaded iron pipe systems are specified. Typical applications include natural gas and propane distribution lines, hydronic heating systems, compressed air runs, and general-purpose water piping. It is sized at 3/4 inch, one of the most common sizes found in residential gas drops and branch supply lines. Plumbers, pipefitters, and HVAC technicians working on iron pipe systems will encounter this fitting as a standard inline connector.

Key Features

• 300 psi liquid and gas pressure rating for demanding service conditions
• 150 psi steam pressure rating suitable for low-pressure steam systems
• Class 150 malleable iron construction for strength and thread durability
• 3/4 inch fitting size covers one of the most common pipe diameters in residential and light commercial work
• Standard NPT threading for straightforward installation with common pipe wrenches and dies

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4 inch threaded iron pipe systems in plumbing, gas distribution, and low-pressure steam applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Plumbing Code, and the International Fuel Gas Code where gas service is involved. Shut off the gas or water supply and depressurize the line completely before threading or removing any fittings. Apply an approved pipe thread sealant or PTFE tape rated for the service type before assembly. Do not overtighten, as malleable iron threads can crack under excessive torque.
