The VALUE COLLECTION 6RSB3/4*3/8 is a 3/4 x 3/8 inch threaded pipe reducer fitting machined from 316 stainless steel. It connects two pipes of different diameters using female NPT threads on both ends, making it a straightforward inline size reduction fitting. Rated to 150 psi at standard service conditions and conforming to Schedule 40 dimensions, this reducer is suited for plumbing, process piping, and fluid-handling systems where corrosion resistance and reliable thread engagement matter. Licensed plumbers and pipefitters install this type of fitting in both residential and commercial applications.
This reducer is used in potable water, chemical, and general industrial piping systems where a transition from 3/4 inch to 3/8 inch pipe is required. Its 316 stainless steel construction makes it appropriate for mildly corrosive environments, marine adjacencies, and food-grade or sanitary adjacent systems where 304 stainless may be insufficient. The FNPT x FNPT end connection accepts standard male NPT threaded pipe or nipples on both the inlet and outlet sides.
Designed as a standard threaded pipe reducer for use with 3/4 inch and 3/8 inch male NPT pipe, nipples, and fittings in Schedule 40 piping systems rated to 150 psi.
Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC or local plumbing code requirements. Shut off and depressurize the supply line completely before removing any existing fittings or making new connections. Apply an appropriate thread sealant tape or compound to the male NPT threads before engaging the fitting, and tighten to a snug, leak-free engagement without over-torquing the stainless threads. Pressure-test the assembly after installation to confirm no leaks before returning the system to service.
