The ASC Engineered Solutions 810081406 is a black malleable iron pipe coupling sized at 2-1/2 inches. This threaded coupling connects two sections of pipe of equal diameter, providing a secure, rigid joint in piping systems. It is manufactured from malleable iron and finished with a black coating, making it appropriate for use in gas, compressed air, and general industrial piping applications. Licensed plumbers and pipefitters typically install this fitting as part of a larger pipe assembly, particularly in commercial and light industrial settings where a durable threaded connection is required.
This coupling is suited for 2-1/2 inch threaded pipe runs in residential and commercial piping systems. Common applications include natural gas distribution piping, compressed air lines, and black iron pipe assemblies used in mechanical rooms, boiler rooms, and industrial process lines. Its standard threaded configuration makes it compatible with NPT-threaded pipe and fittings of the same nominal size.
Designed as a standard threaded replacement coupling for 2-1/2 inch black malleable iron pipe systems using NPT threads.
Installation is typically performed by a licensed plumber or pipefitter. Shut off all gas or fluid supply and depressurize the line before disassembling any portion of the piping system. Apply an appropriate thread sealant or PTFE tape to the male threads before hand-tightening, then wrench-tighten to achieve a leak-free joint. Work must comply with applicable local mechanical and plumbing codes, including IFGC requirements for gas piping applications.
