An alternative seal solution to O-rings for use in reciprocating dynamic or rotary applications, X-rings can typically be retrofitted into existing O-ring grooves.
The profile of the X-ring stops the seal from twisting and rolling, preventing spiral failure often seen when O-rings are used in reciprocating applications. They can also offer a reduction in friction as trapped media between the lobes can provide lubrication to the sliding sealing face.
PPE manufactures X-rings in a range of high performance elastomer materials to standard O-ring sizes, as well as custom sizes for specific applications.
