Need a dependable fitting? Threaded Reducing Tee on MetalMitra comes in standard and custom sizes to ASME B16.11, ready for changes in direction, branching and size transitions.

Through MetalMitra you can source Threaded Reducing Tee in stainless steel, carbon steel, alloy steel, duplex, nickel alloy and other grades, across a broad range of sizes and pressure ratings.

A threaded reducing tee has a smaller threaded branch for taking a reduced line off the run.

Threaded (screwed) fittings are forged fittings with internal or external pipe threads, allowing small-bore piping to be assembled and dismantled without welding. They are used in utility, instrument, air, water and low-to-medium pressure process lines.

Available forms & variants

  • Elbows & Tees — 45°, 90° and street elbows, tees and crosses.
  • Couplings & Unions — Full, half and reducing couplings and unions.
  • Plugs & Bushings — Hex, square and round head plugs, hex bushings.
  • Nipples & Caps — Hex nipples, pipe nipples and caps.

Performance highlights

  • Reduced Branch — Smaller threaded branch port.
  • Compact — Avoids separate bushings.
  • No Welding Needed — Fast to assemble, simple to maintain.
  • Accurate Threads — Threads verified with ring and plug gauges.
