ABSTRACT:
The invention relates specifically to an improved method of joining plastic socket fit piping components for vacuum, pressure, and structural applications where a leak and contamination free connection is needed. A unique Dual Face/Circumferential Elastomer Seal is installed in a special Seal Groove located on the end of the male component. The male components are then inserted into the female sockets until contact is made between the Dual Face/Circumferential Elastomer Seals and the Female Socket Base Surfaces. The final assembly is evacuated with a vacuum pump to actuate and fully compress the seals. The final assembly is then checked for leaks. If the connections are to remain under vacuum and the ability to disassemble is advantageous, no further work is required. If the assembly is to contain positive pressure or withstand heavy structural forces, a hollow, Heated Retaining Plug is inserted through a Female Socket Retaining Collar and the Female Socket Wall into the Male Component Wall, while the assembly is still under Vacuum Seal Actuation/Compression. The number of Heated Retaining Plugs that are inserted is determined by the amount of pressure and structural force that the assembly is required to contain.
