Eldon James British threaded elbow fitting allows for easy change of direction of fluid flow in medical and beverage applications. These elbow fittings come in a variety of chemical-resistant materials with a 1/8 to 1/2in single barb connection on one side and a 1/8 to 3/8in BSPT thread on the other. 

BSPT threads utilize the Whitworth thread form, which is designed to provide a pressure-tight fit through the mating of the threads. This is accomplished by cutting the threads on a taper. Because they are tapered, the thread can only screw into the companion female thread a certain distance before it jams. The standard specifies this distance as a length based on hand-tight engagement; a convenient rule-of-thumb for plastic threads is: finger-tight plus 1/2 to 1 turn with a wrench. Overtightening the plastic thread may cause unwanted stress on the fitting.

The other end of the threaded fitting has a single barb connection that allows the tube to be compressed behind the barb. This creates a more secure seal than multiple barb configurations. They are constructed with an anti-rotation device on the barb shaft to prevent the tubing from rotating or twisting on the elbow fitting, and no parting lines to help prevent leak paths from forming.
