The VALUE COLLECTION 6RSB3X2 is a stainless steel reducer coupling designed for threaded pipe systems using NPT (National Pipe Taper) connections. Reducer couplings join two pipes of different diameters in a single inline fitting, maintaining flow continuity while transitioning between pipe sizes. This fitting is constructed from stainless steel, offering corrosion resistance suited to plumbing, industrial, and mechanical system applications. Licensed plumbers and pipefitters typically handle installation in pressurized fluid or gas piping systems where a size reduction is required at a joint.
This reducer coupling is appropriate for use in residential and commercial piping systems where NPT-threaded connections are standard. Typical applications include process piping, water supply lines, and mechanical room installations. The NPT thread type makes it compatible with standard threaded pipe fittings and valves found across plumbing, HVAC hydronic systems, and light industrial fluid-handling setups. It is packaged as a single unit and is sold individually.
Designed as an OEM-style replacement or direct-install fitting for NPT-threaded pipe systems requiring an inline diameter reduction.
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 pipe system fully before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape to the male NPT threads before assembly, and hand-tighten followed by wrench tightening to avoid cross-threading or over-torquing the stainless threads. Inspect the joint for leaks after restoring system pressure.
