The VALUE COLLECTION 6RSB1/2*3/8 is a threaded pipe reducer fitting designed to transition between 1/2-inch and 3/8-inch pipe lines in plumbing, industrial, and mechanical systems. Constructed from 316 stainless steel with a Schedule 40 wall rating, it connects via female NPT threads on both ends (FNPT x FNPT) and is rated to 150 psi. The 316 alloy provides strong resistance to corrosion and chloride environments, making it appropriate for wet, chemical-exposure, or marine-adjacent applications. Licensed plumbers and pipefitters install this fitting in both commercial and residential systems where a reduced pipe diameter is required at a junction point.
This reducer is suited for use in water supply lines, process piping, compressed air distribution, and light industrial fluid systems that require a step-down from 1/2-inch to 3/8-inch pipe. The all-female NPT thread configuration allows direct connection to male-threaded pipe or fittings on both the inlet and outlet sides. It is commonly used in retrofit and new-construction scenarios where existing pipe runs must transition to a smaller nominal diameter without cutting or welding.
Designed as a standard threaded reducer fitting compatible with 1/2-inch male NPT inlet pipe and 3/8-inch male NPT outlet pipe in Schedule 40 plumbing and process piping systems rated to 150 psi.
Installation should be performed by a licensed plumber or qualified pipefitter following applicable IPC and local plumbing code requirements. Depressurize and isolate the affected pipe segment before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male NPT threads before hand-tightening, then use a pipe wrench to achieve a secure, leak-free connection. Do not overtighten, as this can stress the threads of stainless steel fittings.
