Threadolet Manufacturer in India
Sawariya Metal Industries is a manufacturer, supplier, stockist and exporter of Threadolet in stainless steel, carbon steel, alloy steel, duplex, nickel alloy and other grades, in a wide range of sizes and pressure ratings.
A threadolet is a branch outlet with a female-threaded (NPT) end for screwed branch connections, instruments and gauges.
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.
Key Features of Threadolet
Threaded Outlet
NPT / BSPT female thread.
Instrument Taps
Ideal for gauges and thermowells.
Integral Reinforcement
Designed to reinforce the run pipe at the branch.
Cost Saving
Lighter and cheaper than a full reducing tee.
