THREADED ADAPTERS AND <br />REDUCER BUSHINGS <br />Before making up threaded connections, inspect the threads. <br />Do not use fittings with damaged threads. Inspect all steel <br />threads and remove any burrs. Threads must be clean and <br />dry before applying thread lubricant. When using threaded <br />adapters, thread them into the other system before bonding <br />onto pipe. Unless a union is used, it may be impassible to <br />turn the adapter into the mating thread. For best results use a <br />strap wrench and a solvent -free, soft -set, non-metallic thread <br />lubricant. The thread lubricant must be chemically resistant <br />(compatible) with the petroleum or alcohol product conveyed <br />in the piping system. <br />Threaded Adapters <br />• Do not use thread sealing tapes. <br />• Apply thread lubricant to all threaded surfaces. <br />• Series 7000 or 8000 adhesives may be used in place of <br />thread lube. Do not use PSX adhesives as a thread lube. <br />• Tighten to 1 to 11/ turns past hand tight. <br />• Do not use metallic wrenches that may cause damage <br />to fittings. <br />• Do not over tighten. Tighten the adapters as if they were <br />brass or other soft material. <br />29 <br />
