What is an Integral Seal?
Parker Integral Seals are basically “second generation”
Gask-O-Seals. While still using a retainer, the Integral
Seal does away with grooves to retain the seal elements
and, by bonding the elastomer to the edge of the metal,
reduces the thickness of the retainer allowing the seal
assembly to be used in retrofits of existing designs
having O-Ring grooves or flat flange surfaces.
Advantages of the Integral Seal
The Parker Integral Seal offers the user all lthe advantages
shown on page 5-135 under “Gask-O-Seal Advantages”
plus the very important retrotit benefit. This “retrofit
potential” has proven to be a real plus with users of the
Integral Seal as an economical solution to many sealing
problems. The illustration below shows a typical retrofit
situation using both “flat plate” and “pre-grooved” examples.
