The MERIT BRASS SW3612D-0604 is a socket weld pipe reducer fitting designed to transition from a 3/8-inch pipe connection down to a 1/4-inch pipe connection in high-pressure fluid and gas piping systems. Constructed from 316 stainless steel, this reducer delivers strong corrosion resistance in aggressive environments including marine, chemical processing, and sanitary applications. It carries a pressure rating of 3,000 psi, making it suitable for demanding industrial and commercial installations. The socket weld end connections on both sides allow a licensed pipefitter or plumber to insert pipe ends directly into the fitting sockets before welding, creating a secure, leak-resistant joint.
This reducer is used in commercial and industrial piping systems where a controlled pipe size reduction is required without threading. Typical applications include process piping, hydraulic lines, instrumentation tubing runs, and steam or chemical service lines where 316 stainless steel material grade is specified for corrosion resistance. It is sized for a 3/8-inch inlet to a 1/4-inch outlet and is sold individually, making it practical for both single-unit repair work and larger installation projects requiring exact quantities.
Designed as an OEM-style socket weld reducer fitting for 3/8-inch by 1/4-inch pipe installations in systems specifying 3,000 psi-rated 316 stainless steel fittings.
Installation of socket weld fittings should be performed by a qualified pipefitter or licensed plumber in accordance with applicable codes such as ASME B16.11 and the International Plumbing Code. Depressurize and fully isolate the piping system before cutting or fitting any section. Pipe ends must be clean, deburred, and properly sized to seat correctly into the socket before welding. Do not apply pressure to the system until all welds have been completed and inspected per applicable standards.
