Glass bends are ideal for applications requiring extended wear life beyond that experienced with standard stainless steel bends such as transmitting highly abrasive plastic pellets and similar abrasive materials. Glass bends are designed to match the inside diameter of 16 Ga. tubing, eliminating the step that exists with metric dimension products. Bends are available in 90° and 45° with a radius of either 9 or 18 inches. Also available are couplings with stepped gaskets to connect bends to tubing.
