The ASC Engineered Solutions 8700133054 is a 3/8 inch malleable black iron coupling designed to join two pipes running in the same direction. Malleable iron construction provides the tensile strength and impact resistance required for threaded pipe assemblies in gas, steam, and water distribution systems. This fitting is sold individually and is installed by licensed plumbers and pipefitters working on commercial and residential piping systems where a reliable, rigid inline connection is needed.
This coupling is suited for use in low-pressure gas distribution, steam piping, and water supply lines where malleable black iron fittings are specified. It is commonly used in residential and light commercial mechanical rooms, boiler rooms, and utility installations where threaded pipe connections are standard practice. The 3/8 inch size is typical for branch supply lines and smaller distribution runs.
Designed as an OEM-style replacement or new-installation fitting compatible with standard 3/8 inch threaded malleable iron pipe systems.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Plumbing Code. Shut off and depressurize the affected line before disassembling or installing any threaded fittings. Apply approved pipe thread sealant or PTFE tape to male threads before assembly. Do not overtighten threaded connections, as malleable iron fittings can crack if excessive force is applied.
