Weld Elbows — 316 Stainless Steel

About Tube Socket Weld Elbows

Tube socket weld elbows turn instrumentation tubing through 90° at a threaded port, with a welded joint on the tube side. The tube sits in the elbow's socket and is fillet welded, so the change of direction is permanent and has no compression parts that could loosen. The threaded end is NPT, either male or female.

An elbow is often a better choice than bending the tube close to a port. A bend needs a minimum straight length before the fitting and a minimum radius, which can be hard to achieve on compact skids, analyser panels or near large valve actuators. A socket weld elbow takes the turn at the fitting itself, so the tube can run straight into it.

The male elbow screws into a female NPT port, while the female elbow accepts a male NPT part such as a nipple, plug or instrument connection. Both are SS316 and listed in tube sizes from 1/8" to 2" and 6 mm to 38 mm. Because the angle of an NPT joint depends on how far the thread is tightened, it is usually easier to make up the threaded connection and set its orientation before welding the tube.

• Choose male or female by the gender of the mating NPT thread.
• Switch between imperial and metric sizes with the unit toggle.
