static seals

Cover seals are designed to provide reliable sealing solutions, especially in situations with static seal gaps, pressure variations, or the need to prevent leakage and contamination.

Quad rings nearly have the same sealing principle as the O-ring sealing. However, they provide less friction than the conventional O-ring and there is no spiral twist. It eliminates the tendency to roll in the groove. The sealing is achieved by the diametrical squeeze in a right angled groove. The system pressure creates a positive sealing force.

This is a profile which is an excellent replacement for o-rings and backup ring combinations. For non standard grooves they provide an excellent sealing in high pressure and wear applications.

O-Rings are the simplest form of sealing that are used in both dynamic as well as static applications. For dynamic applications they are used in rotary as well as axial applications. The selection of o-rings depends on temperature, pressure and fluid.
