A Fresh Look at Sealing - Design Feature: A non-spliced (one-piece) Teflon seal element, available from 1/2" to 24". Combining this seal with the incline-plane groove design is a first for this generation of gasket technology; an excellent choice for engineers and end users wanting increased seal integrity.

The flange face makes initial/light contact with the gasket retainer surface (isolation material) and the sealing element protrudes just above the gasket retainer surface.

Rectangular Sealing Element "Quad Seal" in conjunction with the incline plane provides a self-energized seal. The small gap between seal element and retainer illustrates how the incline plane allows the seal material to move in a direction other than point loading the gasket web (small area of retainer between the two seals). This movement prevents cracking and breaking of the gasket retainer under high loads.

Furthermore, the incline plane groove provides the seal with greater elastic memory, thereby helping maintain an effective seal even when bolt load may relax over a period of time.
