The VALUE COLLECTION 6RSB1X1/8 is a stainless steel reducer coupling designed for connecting pipe sections of two different diameters within a single threaded fitting. It uses NPT (National Pipe Taper) threads on both ends, making it compatible with standard threaded pipe systems used in plumbing, HVAC, and industrial piping applications. The stainless steel construction provides corrosion resistance in demanding service environments. This fitting is a practical solution for plumbers, pipefitters, and mechanical contractors who need a reliable, code-appropriate transition between pipe sizes without additional adapters or unions.
This reducer coupling is suited for residential and light commercial piping systems where a threaded NPT connection is required between two different pipe diameters. It is commonly installed in water supply lines, compressed air systems, and mechanical room piping. The fitting ships individually and is intended for single-unit replacement or small-scope maintenance work.
Designed as an OEM-style replacement reducer coupling for standard NPT-threaded pipe systems in plumbing, HVAC, and mechanical piping applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local plumbing codes. Shut off and depressurize the system completely before removing or installing any threaded fitting. Apply appropriate thread sealant tape or compound to NPT threads before assembly and tighten to snug plus wrench-tight using a pipe wrench — do not over-tighten stainless steel fittings to avoid thread galling. Pressure-test the system after installation before returning it to service.
