The ASC Engineered Solutions 812507804 is a 3/8-inch black malleable iron union designed for joining threaded pipe sections in gas, air, and fluid distribution systems. Malleable iron construction provides reliable strength and impact resistance in demanding trade environments. The black coating offers standard corrosion protection suitable for above-ground piping applications. This union allows technicians to disconnect and reconnect threaded pipe runs without cutting, making it a practical component for maintenance and service work on mechanical systems.
This fitting is commonly used in residential and light commercial piping systems, including gas distribution, compressed air lines, and general plumbing applications. The 3/8-inch size suits branch lines and smaller-diameter runs where a removable, threaded connection point is required. Licensed plumbers, pipefitters, and HVAC technicians routinely install this style of union during new construction and retrofit work.
Designed as a standard threaded union fitting compatible with 3/8-inch NPT pipe systems in gas, air, and general fluid piping applications.
Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable codes such as the IFGC or IPC. Shut off and depressurize the line before disassembly or installation. Use appropriate thread sealant rated for the service medium when making up connections. Do not over-torque threaded fittings, as malleable iron can crack under excessive force.
