ABSTRACT:
A weld-free all purpose seal for closed fluid systems is disclosed. This sealing device includes a ring body having a flanged top member for coupling to a pipe with a first plurality of apertures in spaced relationship therethrough. The ring body is recessed in the bottom member with a lip extending beyond the apertures. A flexible annular seal is provided having the reduced diameter from top to bottom adapted to be integral with the lip surface of the ring body. A wedge block is also provided with a planar top surface with a second plurality of apertures in spaced aligned relationship with the first plurality and continuing therethrough. The wedge block being of reduced diameter from bottom to top and adapted to receive the flexible annular seal. The wedge block may also have a diameter to interconnect with the recessed area of the ring body bottom member. Metal bolts extend through the first and second plurality of apertures drawing the ring body and wedge block into pressure engaging relationship thus completely capturing the flexible annular seal therebetween.
