Product Overview

X-rings can be used in a wide variety of static and dynamic sealing applications.  They are available in standard O-ring sizes.

Their four-lobed design provides a larger sealing area in comparison to a standard O-ring.  The double seal action requires lower squeeze levels to maintain an effective seal, thus reducing friction level and improving seal life.

X-ring parting lines are between the lobes, away from the sealing surface, therefore eliminating the problems of leakage often resulting from a parting lines irregular surface as found on an O-ring.

X-rings are designed to out perform a standard O-ring in rotary seal applications.

The four lobed configuration creates a more stable seal avoiding spiral twisting which can occur in reciprocating applications.
