The ASC Engineered Solutions 320200017 is a straight tapped black steel coupling designed for joining threaded pipe sections in gas, air, and fluid distribution systems. Machined from black steel, this 1/4-inch coupling provides a durable, pressure-rated threaded connection suitable for both residential and light commercial piping applications. Its straight tapped configuration accepts standard NPT-threaded pipe on both ends, making it a reliable mechanical fitting for plumbers, pipefitters, and HVAC technicians working on low-pressure gas lines, compressed air systems, or water distribution runs.
This coupling is suited for use in residential and commercial piping systems where a 1/4-inch threaded straight connection is required. Typical installations include gas distribution manifolds, compressed air supply lines, and general plumbing rough-in work. The black steel construction makes it appropriate for dry or gas service applications rather than potable water lines where galvanized or brass fittings are more commonly specified.
Designed as an OEM-style replacement or new-install fitting for 1/4-inch NPT threaded piping systems in gas, air, and general industrial fluid service applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC or IPC requirements. Shut off and depressurize the line before disassembling or installing any threaded fitting. Apply an approved thread sealant or PTFE tape to all male NPT threads before assembly. Black steel couplings are not recommended for potable water or outdoor exposed applications without additional corrosion protection.
