save time and money with fast ® simple lightweight dur o lok pipe couplings tapered i.d hub split coupler material 18-8 ss set screw hub o-ring or high temperature gasket wedge shaped teeth tapered o.d split coupler the dur o lok® wedge system the heart of the dur o lok® design is the system of wedge-shaped circumferential teeth located on the outside diameter of the hubs and on the inside diameter of the mating split coupler the wedging action of the teeth compresses the gasket and brings the hub ends into contact with each other the outside diameter of the split coupler is tapered a ring with a tapered inside diameter slides over the split coupler ring segments forcing them together and holding them firmly in place the tapered retaining ring is secured with a set screw the entire connection process can be accomplished in less than a minute without wrenches patented and patents pending www.bete.com ®2004 bete fog nozzle inc all rights reserved bete www.durolok.com
