The ANVIL INTERNATIONAL INC 8700121604 is a black malleable iron reducing tee designed for threaded pipe assemblies in plumbing, HVAC, and industrial piping systems. This fitting connects a 1-inch run on both ends to a 3/4-inch branch outlet, allowing flow to be directed or divided between lines of different diameters. The black finish indicates an uncoated malleable iron construction suited for gas, air, and water distribution lines. Licensed plumbers and pipefitters install this fitting in both new construction and retrofit applications requiring a reliable threaded branch connection.
This reducing tee is used in residential and light commercial piping systems where a main line must tap off to a smaller branch. Common applications include natural gas distribution, compressed air systems, and hydronic heating piping. The 1-inch by 1-inch by 3/4-inch configuration is a frequently specified size in branch takeoff scenarios throughout mechanical rooms, utility spaces, and inline distribution runs. It is sold in packages of 15 units, making it practical for contractors working on multi-point installations.
Designed as an OEM-style replacement and standard-fit reducing tee for threaded malleable iron pipe systems using NPT connections in residential and commercial plumbing, gas, and HVAC piping applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IFGC requirements. Shut off all gas or fluid supply and relieve system pressure before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to male NPT threads before assembly. Do not overtighten threaded connections, as this can crack malleable iron fittings.
