The ASC ENGINEERED SOLUTIONS 321200008 is a straight tapped galvanized steel coupling designed for pipe joining applications in plumbing, HVAC, and mechanical systems. This fitting connects two pipe sections in a straight run using a tapped configuration, allowing for secure, threaded engagement. Constructed from galvanized steel, it resists corrosion in typical indoor piping environments. At 0.03 pounds, it is a compact, lightweight fitting suited for 1/8 inch pipe sizes. Licensed plumbers, pipefitters, and mechanical contractors install this type of coupling during new construction and service work.
This coupling is used in residential and light commercial applications where small-diameter threaded pipe connections are required. Common install scenarios include gas supply branch lines, low-pressure air lines, instrumentation piping, and condensate or drain configurations that call for 1/8 inch threaded fittings. The straight tapped design maintains inline flow direction without offset, making it a standard choice for direct pipe extension or repair work on small-bore threaded systems.
Designed as an OEM-style replacement or standard fitting for 1/8 inch threaded pipe systems in residential and light commercial plumbing, HVAC, and mechanical piping applications.
This fitting is installed by licensed plumbers or pipefitters working on threaded small-bore piping systems. Shut off all pressure to the line before disassembling or installing any threaded fitting. Apply appropriate thread sealant or PTFE tape to all male threads prior to assembly, and tighten to a snug, leak-free fit without overtightening, which can crack fittings or damage threads. Work must comply with applicable local plumbing codes and IFGC or IPC requirements where relevant.
