6. Be sure that the plain end is beveled; square or sharp edges may damage or dislodge the gasket and cause a leak. The plain end of the pipe must be cleaned of all foreign matter on the outside from the end to the stripes. Frozen materials may cling to the pipe in cold weather and must be removed. In all cases, it is desirable to apply a thin film of lubricant to the outside of the plain end for about 3″ back from the end. Do not allow the plain end to touch the ground or trench side after lubricating since foreign matter may adhere to the plain end and cause a leak. Lubricant other than that furnished with the pipe should not be used.
7. The plain end of the pipe should be in reasonably straight alignment and carefully entered into the socket until it just makes contact with the gasket. This is the starting position for the final assembly of the joint. Note the two painted stripes near plain end.
8. Joint assembly should then be completed by forcing the plain end of the entering pipe past the gasket (which is thereby compressed) until the plain end makes contact with the bottom of the socket. Note that the first painted stripe will have disappeared into the socket and the front edge of the second stripe will be approximately flush with the bell face. If assembly is not accomplished with the application of reasonable force by the methods indicated, the plain end of the pipe should be removed to check for the proper positioning of the gasket, adequate lubrication, and removal of foreign matter in the joint.
9. For joint assemblies 8″ and smaller, socketing of the plain end may be accomplished in some cases by pushing against the face of the bell of the entering pipe with a crowbar or spade. Large sizes require a more powerful means.
