The ASC Engineered Solutions 8700132957 is a 1/8 inch malleable black iron pipe coupling designed to join two pipes running in the same direction. Malleable iron construction provides the tensile strength needed for threaded pipe systems in demanding service environments. This fitting is a standard inline connector used by plumbers and pipefitters working on black iron pipe runs in gas, industrial, and general plumbing applications.
This coupling is suited for residential and light commercial installations where black iron threaded pipe is specified. Typical applications include natural gas distribution lines, steam systems, and industrial pipe assemblies. The 1/8 inch size serves smaller-diameter branch lines and instrument connections where a reliable, pressure-rated threaded joint is required.
Designed as an OEM-style replacement fitting for standard 1/8 inch NPT black iron threaded pipe systems.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, including IFGC requirements for gas piping systems. Shut off and depressurize the pipe system completely before removing or installing any fittings. Apply an approved thread sealant or PTFE tape rated for the intended service medium to all threaded connections. Do not over-tighten threaded fittings, as malleable iron threads can crack under excessive torque.
