Fluorocarbon (FPM, FKM, Fluorocarbon FKM) 75 Durometer X-Rings

Fluorocarbon is a well- known high performance rubber, and especially it has excellent resistance to high temperature, ozone, weather, oxygen, mineral oil, fuels, hydraulic fluids, aromatics and many organic solvents and chemicals.

X-Rings have a double sealing function as compared to an O-Ring and can be used in a wide variety of static and dynamic sealing applications.

The four-lobed design provides twice the sealing surface in comparison to a standard o-ring. The double-seal action requires less squeeze to maintain an effective seal. This reduction in squeeze means less friction and improved seal life.

Additionally, X-Ring parting lines are between the lobes, away from the sealing surface. This eliminates the issue of leakage often resulting from a parting line's irregular surface as found on an O-Ring.

X-Rings are also designed to outperform a standard O-Ring in rotary seal applications. The four-lobed configuration creates a more stable seal to avoid spiral twisting. This allows the use of a narrower groove width than a standard O-Ring groove, but can also be used in a standard O-Ring groove.

Advantages of X-Rings vs. O-Rings

  • Avoid twisting in the groove. The seal does not tend to roll in the groove during reciprocating movement.
  • Low friction. It requires less radial squeeze than a comparable O-ring.
  • Less friction means less wear, and thus a longer service life.
  • Very good sealing efficiency due to it special profile.
  • A lubricant reservoir formed between the sealing lips improves start up
