To drain off condensate from rolls, cylinders or dryers, Syphon Elbow is the only scientific design outdating the use of crudely bent ordinary stationary pipe-an economical loss. The Syphon Elbow does the job well with two straight pipes attached at either end. Syphon Elbow, being hinged, is inserted or withdrawn safely from the joint and it closes to a leak proof seat by its own weight inside the roll. Syphon Elbow is made of virgin quality G.M. with stainless steel valve insert or complete stainless steel solid bar stock construction.
