Custom Gask-O-Seals® and Integral Seals™

Gask-O-Seals® are static structural gaskets composed of a uniquely designed elastomeric element molded directly into machined or formed grooves of a metal or thermoplastic retainer plate to produce a simple single-piece solution.

Integral Seals™ are structural gaskets composed of an elastomer bead edge bonded to the ID/OD of a rigid metal (or other substrate) frame or carrier plate to be used between two static mating flanges.

Advantages of their one-piece, composite design which is produced by molding processes that vulcanize the rubber sealing profile to the substrate, include:

      • Ease of assembly to significantly reduce installation time and complexity compared to other sealing products

      • Elimination of secondary machining of mating hardware, which reduces hardware costs

      • A robust, chemically bonded seal which prevents failure due to the elastomer falling out of place during installation or in application

      • Customized pre-engineered compression and fill ratios that deliver optimum fool-proof performance and eliminate necessity of re-torqueing

Gask-O-Seal® Features & Benefits:

      • Elastomer element specifically suited to meet application requirements including high temp service, low temp service, high pressure conditions, vacuum, exposure to high swell fluids, or high permeation gases

      • Retainer thickness: Typically specified in standard gauge thicknesses as low as .025", Gask-O-Seals can be molded into any metal, thermoplastic, composite, or even ceramic substrate with sufficient thickness where a suitable groove for molding can be specified.

      • Elastomer Bonding:

                  • Mechanical Bonding: A retainer can be designed with mechanical locking features within the groove or rubber flow-through holes to mechanically retain the seal to the retainer.

                  • Chemical Bond:  A chemical bonding agent is applied to the groove(s) prior to molding.  During the molding process, the rubber compound reacts with this bonding agent, a process call co-vulcanization, to chemically bond the sealing element to the retainer. 

      • Highly customizable gasket-type sealing solution

      • The integrated volume/void design insures proper sealing load and rubber resilience without a machined groove in the flanging.

      • The metal to metal, pass-through loading eliminates re-torquing due to sealant creep

      • Rigid structural frame allows exact seal bead placement on a thinner flange wall and around bolt holes and multiple sealed ports

      • Rigid structural frame allows robotic assembly of the gasket to the flanging

      • Molded or stamped features in the metal frame allow the ability of the gasket to cling to the flange it’s placed on while maneuvering the flange during assembly

      • Separate gasketing outside a groove or without cure-in-place gasketing allows faster, cleaner serviceability

      • The structural frame allows sealing multiple ports with high pressure differential across the same flange, with one gasket

      • Through-hole bolt holes can be sealed independently of the main flange with the same gasket

      • Bolt retention features can be molded into the gasket to allow bolts to be partially inserted without separation from the flange
