Eldon James British Threaded Elbow Fitting

Eldon James British threaded elbow fitting allows for easy change of direction of fluid flow in medical, automotive, 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.
