Need a dependable branch outlet? Elbolet on MetalMitra comes in all major branch sizes and ratings to MSS SP-97, ready for reinforced branch connections on run pipe.

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

An elbolet is a branch outlet contoured to fit the outside of a long or short radius elbow, used for thermowells and drains on elbows.

Olets are forged branch outlet fittings welded onto the run pipe to create a reinforced branch connection. They are a compact, cost-effective alternative to reducing tees and allow branches to be added at any position along the run pipe.

Available forms & variants

  • Weldolet — Buttweld branch outlet for full-flow branches.
  • Sockolet & Threadolet — Socket weld and threaded outlets for small-bore branches.
  • Elbolet & Latrolet — Outlets for elbows and 45° lateral branches.
  • Nipolet, Sweepolet & Flangeolet — Integral nipple, contoured and flanged outlets.

Performance highlights

  • Elbow Contour — Fits LR and SR elbows.
  • Instrument Use — Common for thermowells.
  • Integral Reinforcement — Designed to reinforce the run pipe at the branch.
  • Cost Saving — Lighter and cheaper than a full reducing tee.
