Delta gaskets

Because of their geometric shape, delta gaskets require a higher level of precision from the seal grooves. As a direct result of the manufacturing process and its resulting preci­sion, delta gaskets are only used for high-pressure auto­claves and high-pressure connections up to a maximum of 2000 mm, whereby the majority are less than 1000 mm. The following illustration shows the application as a cover gas­ket.

Due to its splined profile, an excellent initial seal is created by the partial plastic deformation of the opposing peaks of the gasket when bolt pre-tensioning force is applied. The radially self-sealing effect arises due to the high internal pressure resulting from the elastic extension of the gasket.
