X-ring 139,37x2,62 EPDM 70

The four-lobed design of the EPDM X-rings is specially developed as the sealing profile of these seals provides twice the sealing surface of ordinary O-rings. The design of the EPDM X-rings not only provides lower fiction than an O-ring, but also, due to its square cross section, it resists spiral twist. EPDM X-Rings are available in a wide range of elastomer materials for both standard and special applications.
Their dimensions are specified with the inside diameter d1 and the cross-section. X-Rings are are completely interchangeable with O-rings in the same sizes. They can be used in lot of static and dynamic sealing applications including rotary, reciprocating or oscillating motion.
