Anvil 0310079603 Malleable Iron Coupling 1/8 in Threaded

Product Description

The ANVIL 0310079603 is a Class 150 malleable iron pipe coupling with a black finish and threaded end connections sized at 1/8 inch. It carries a 300 psi pressure rating for both liquid and gas service, making it suitable for a wide range of low-pressure piping applications. Manufactured to ASME B1.20.1 and ASME B16.3 standards, and listed to UL/FM and ASTM A197, this coupling meets the compliance requirements typically demanded on commercial and light industrial jobsites. Licensed plumbers, pipefitters, and mechanical contractors install this fitting as part of threaded black iron piping systems.

This coupling is appropriate for residential and commercial gas distribution piping, fire protection systems, and general-purpose liquid or air piping where threaded malleable iron fittings are specified. Its black finish is standard for gas piping installations. The 1/8 inch size suits branch lines, pilot gas connections, and small-diameter utility runs commonly found in HVAC equipment connections and plumbing rough-in work. It is sold and packaged as a single unit.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes including the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off and depressurize the piping system completely before disassembly or fitting installation. Apply listed pipe thread sealant or PTFE tape to male threads before assembly. Do not overtighten threaded connections, as malleable iron fittings can crack under excessive torque.
