The ANVIL INTERNATIONAL INC 8700133302 is a 1-1/2 inch black malleable iron coupling with right-hand thread, designed for joining sections of pipe in standard threaded piping systems. Malleable iron construction gives this fitting the strength and ductility needed for both residential and commercial applications. The black finish indicates a non-galvanized treatment suitable for gas, steam, and general industrial piping where galvanized fittings are not required. Licensed plumbers and pipefitters install this type of coupling when extending or repairing threaded pipe runs.
This coupling is suited for low-pressure gas distribution, steam heating systems, water distribution, and general industrial pipe assemblies. It is typically used in environments where a durable, iron-body threaded fitting is specified. The right-hand thread configuration follows standard NPT practices and mates with conventional pipe and fittings of the same nominal size. Applications include commercial and residential mechanical rooms, boiler rooms, and process piping installations.
Designed as an OEM-style replacement or new-installation fitting for 1-1/2 inch nominal threaded pipe systems using standard right-hand NPT threads.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IFGC requirements where gas service is involved. Shut off all gas or fluid supply and depressurize the line before removing or installing any threaded fittings. Apply appropriate thread sealant or PTFE tape to male threads before assembly. Do not over-tighten, as malleable iron fittings can crack under excessive torque.
