The EVERFLOW SS4CPL012 is a 1/2-inch stainless steel 304 coupling designed for joining pipe sections in plumbing, HVAC, and light industrial piping systems. Constructed from Type 304 stainless steel, this coupling resists corrosion and performs reliably in wet, high-humidity, or chemically active environments. It is sold as a single unit and is well suited for licensed plumbers and pipefitters working on both residential and commercial installations where durability and material compatibility are priorities.
This coupling is appropriate for use in water supply, hydronic heating, and process piping applications where stainless steel fittings are specified. The 1/2-inch size fits standard half-inch pipe runs commonly found in residential plumbing rough-in work, boiler loop connections, and light commercial mechanical systems. Installers typically select this fitting when the application demands corrosion resistance beyond what standard brass or galvanized fittings provide.
Designed as an OEM-style replacement or new-installation fitting for standard 1/2-inch pipe systems requiring Type 304 stainless steel construction.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local plumbing code requirements. Shut off and depressurize the water or fluid system completely before cutting into any pipe or removing existing fittings. Use appropriate thread sealant or joining method specified for stainless steel fittings in the system design. Inspect mating pipe ends for burrs or damage before making the final connection.
