What are Sandwich Gaskets and Manifold Bolt French Locks?

Sandwich Gaskets are gaskets that sits between two major components, generally found in engines. Its purpose is to seal the components to ensure maximum compression and avoid leakage of anything moving through or around the components. The sandwich gasket is the most critical sealing application in any engine. A sandwich gasket must shares the same strength requirements as the components it sits between.

Some of our sandwich gaskets are not made of the three components, but we still refer to them as “sandwich gaskets” because they perform the same function.

Manifold Bolt French Locks are simply used to hold the sandwich gaskets in place. Material choice is essential, because like the sandwich gasket, it must exhibit the same strength or greater than the components it is sealing.
