The ASC ENGINEERED SOLUTIONS 318900685 is a malleable iron pipe cap designed to close off the end of a 1-1/2 inch threaded pipe. The black coating provides corrosion resistance and a finished appearance suited for exposed or concealed installations. At 0.73 pounds, this domestically produced fitting delivers the durability expected in gas, air, and general industrial piping systems. Plumbers, pipefitters, and HVAC technicians use malleable iron caps as permanent or semi-permanent end closures where a threaded termination is required.
This cap is appropriate for residential and light commercial piping applications including natural gas distribution lines, compressed air systems, and black iron plumbing assemblies. It is commonly installed at capped branch tees, unused outlet ports, and service terminations where the system may be extended at a later date. The black iron finish makes it a direct fit in standard black malleable iron fitting assemblies without mixing material finishes.
Designed as an OEM-style replacement or new-installation fitting for 1-1/2 inch threaded black iron pipe systems in residential and commercial plumbing, gas, and air distribution applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IFGC requirements for gas systems, or IPC requirements for plumbing systems. Depressurize and shut off the supply line before threading the cap onto the pipe end. Apply an appropriate thread sealant or pipe tape rated for the service medium before tightening. Do not over-torque malleable iron fittings, as the material can crack under excessive force.
