Black reducing coupling with tapered ends and threaded openings

Legend Valve

Legend Valve 350-560 3 x 2-1/2 Black Reducing Coupling

SKU CH-J9DB-V8MDN

Connects 3-inch and 2-1/2-inch female NPT threads in black iron piping

  • Reduces pipe diameter from 3 inch to 2-1/2 inch
  • Female NPT threads on both ends for secure connections
  • Black steel construction resists corrosion in plumbing systems
  • California Proposition 65 warning for cancer risk
  • California Proposition 65 warning for reproductive harm risk

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.
