The primary method of fastening and sealing a Kwik-Flange™ is achieved by a hinged
radial clamp that provides uniform compression of an elastomer gasket secured
between two mating flanges.
The elastomer gasket is mounted on a stainless steel
centering ring with tubular rims or extensions that protrude on either side of the
gasket. These rims or extensions fit into locater grooves on the respective mating
flanges and conveniently center the gasket between the flanges prior to sealing. The
seal is made on the flat surfaces outside the locater groove or
counterbore. The seal can
be made quickly by finger-tightening a wing nut on the all-metal hinged aluminum clamp
or by securing bolts in an alternate crisscross pattern on the aluminum
bulkhead style clamps. In both cases a uniform pressure is applied around the outer
flange surfaces to make a reliable seal.
