The ASC Engineered Solutions 8700133203 is a 1-inch malleable black iron pipe coupling designed to join two pipes running in the same direction. Malleable iron construction provides the tensile strength required for demanding piping systems, making this fitting a reliable choice for gas, steam, and water distribution lines in both new construction and retrofit work. The coupling is sold individually and is a standard trade-supply fitting used by licensed plumbers and pipefitters working on commercial and residential systems.
This coupling is suited for use in residential and light commercial piping applications where a straight pipe-to-pipe connection is needed. It is commonly installed in natural gas supply lines, low-pressure steam systems, and water distribution runs where malleable iron fittings are specified. The 1-inch nominal size fits standard Schedule 40 threaded pipe.
Designed as an OEM-style replacement or new-installation fitting for 1-inch nominal threaded malleable iron piping systems.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and IFGC code requirements. Shut off and depressurize the supply line completely before cutting into any existing piping. Apply an approved thread sealant or PTFE tape to all male threads before assembly. Do not overtighten threaded connections, as malleable iron fittings can crack under excessive torque.
