- All foreign matter in the socket must be removed, i.e., mud, sand, cinders, gravel, pebbles, trash, frozen material, etc. The gasket seat should be thoroughly inspected to be certain it is clean. Foreign matter in the gasket seat may cause a leak. Do not lubricate the inside of the bell.
- The gasket must be wiped clean with a clean cloth, flexed, and then placed into the socket with the rounded bulb end entering first. Looping the gasket in the initial insertion will facilitate seating the gasket heel evenly around the retainer seat. Smaller sizes require only one loop. With larger sizes it will be helpful to loop the gasket at the 12 o’clock and 6 o’clock positions. When installing TYTON JOINT pipe in subfreezing weather, the gaskets, prior to their use, must be kept at a temperature of at least 40′F by suitable means, such as storing in a heated area or keeping immersed in a tank of warm water. If the gaskets are kept in warm water, they should be dried before placing in the pipe socket.
- The seating of the gasket may be facilitated by flexing the gasket on one or two points depending on size and then pressing the bulge or bulges out.
- The inner edge of the retaining heel must not protrude from the retaining bead of the socket.
- A thin film of pipe joint lubricant should be applied to the inside surface of gasket which will come in contact with plain end of the pipe.
