The VALUE COLLECTION 6RSB2X1 is a stainless steel reducer coupling designed to connect two pipes of different diameters within a threaded piping system. Both ends use National Pipe Taper (NPT) threading, providing a pressure-rated, leak-resistant connection when properly installed. The stainless steel construction offers corrosion resistance suitable for plumbing, HVAC condensate, and light industrial piping applications. This fitting is sold individually and is a standard choice for plumbers and pipefitters working on systems that require a diameter reduction in the line.
The 6RSB2X1 reducer coupling is appropriate for residential and light commercial piping installations where a threaded NPT connection is required between two different pipe sizes. It is commonly installed in water supply lines, condensate drain systems, and other fluid-handling applications where stainless steel corrosion resistance is preferred over brass or black iron. Licensed plumbers and pipefitters typically handle installations involving this type of threaded reducer in pressurized systems.
Designed as an OEM-style replacement and standard-fit reducer coupling for NPT-threaded piping systems requiring a diameter transition.
Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable IPC or local plumbing codes. Shut off and depressurize the supply line before removing any existing fittings. Apply thread sealant tape or pipe compound to the male NPT threads before assembly to ensure a leak-free joint. Do not overtighten threaded connections, as this can crack or distort the fitting.
