The ASC Engineered Solutions 361175102 is a forged steel threaded reducing coupling designed to connect piping of two different sizes in pressurized fluid and gas systems. Built to 3000 lb class standards, this fitting transitions a 3/8-inch line down to a 1/8-inch line using standard tapered threads. The forged steel construction provides the structural integrity required for demanding industrial and mechanical applications. Licensed plumbers, pipefitters, and HVAC technicians typically install this type of fitting during new construction, system retrofits, or service work requiring a pipe size reduction at a threaded joint.
This reducing coupling is suited for use in commercial and industrial piping systems where a threaded transition between 3/8-inch and 1/8-inch pipe is required. Common applications include compressed air distribution, hydraulic lines, steam systems, and gas-supply piping where a compact, high-strength threaded fitting is specified. Its compact forged body fits in tight spaces typical of mechanical rooms and equipment enclosures.
Designed as an OEM-style threaded reducing coupling for use in 3000 lb class forged steel piping systems requiring a 3/8-inch to 1/8-inch pipe size transition with standard tapered threads.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code or ASME B31 piping standards. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly, and tighten to the fitting manufacturer's recommended engagement using pipe wrenches. Do not overtighten, as this can crack forged fittings or distort threads.
