Plumbing Reducing Coupling
This 3-inch by 2-1/2-inch black reducing coupling connects female NPT threads of different diameters in a plumbing system. It is built for installers and maintenance crews who need a durable, code-compliant transition between pipe sizes. The Legend Valve brand marks it as a standard supply-house component for water, gas or compressed-air lines.
Replaces Mismatched Fittings
The coupling replaces improvised bushings or multiple fittings when joining 3-inch and 2-1/2-inch pipe runs. The jump is worth it whenever a single, factory-threaded fitting saves labour and reduces potential leak paths compared with assembling separate reducers and nipples on site.
Handles Standard Pressure Service
The fitting comfortably handles typical residential and light-commercial pressure ratings for black steel pipe. It runs out where system pressure exceeds the coupling’s class rating or where chemical compatibility requires stainless steel or specialised alloy instead of standard black iron.
