Abstract A method for assembling a seal unit including two opposed conduit parts and a composite sealing ring adapted to be interposed therebetween. The sealing ring includes deformable material on the outer periphery and flexible sealing flanges extending about at least a portion of the deformable material. The seal is partially inserted into the cavity of one conduit part until the deformable material contacts the internal sealing surface of that part. Afterwards the second conduit part is placed over the exposed portion of the seal to cause the internal sealing surface of the second part to contact the deformable material. The two conduit parts are drawn together to thereby cause the deformable material to deformingly contact the internal surfaces of the conduit parts and are subsequently drawn further together to cause the deformable material to flex the sealing flanges of the sealing ring into engagement with the internal sealing surfaces of the conduit parts.
In a method for assembling a seal unit wherein the seal unit includes two opposed conduit parts and a composite sealing ring adapted to be interposed between the conduit parts, and wherein the sealing ring includes an elastically deformable material on the outer periphery thereof and flexible sealing flanges on the outer periphery of the ring extending about at least a portion of the deformable material, the method comprising: partially inserting the seal into the cavity of one conduit part until the elastically deformable material contacts the internal sealing surface of the one conduit part, placing the second conduit part over the exposed portion of the seal to cause the internal sealing surface of the second conduit part to contact the elastically deformable material, drawing the two conduit parts together to thereby cause the elastically deformable material to conformingly contact the internal surfaces of the conduit parts, and drawing the two conduit parts further together to cause the elastically deformable material to flex the sealing flanges of the composite sealing rings into engagement with the internal sealing surfaces of the conduit parts.
