What Makes Multiseal® Low Friction Seals Better?
  • A better seal - The multi-lobed design provides more sealing surfaces than standard O-Rings.
  • Increases life for the seal ring - With multiple seal points, less squeeze is required to provide an effective seal. This means less friction and wear which will increase seal life and lower maintenance costs.
  • Prevents spiral failure - The square cross sections resist distortion called "spiral twist" that may be encountered when using O-Rings.
  • Puts parting lines where they belong - Unlike an O-Ring, where the parting line is found on the only sealing surface, the parting lines of Multiseal® low friction seals and X-Ring compression seals are located in the center of the cross section away from the primary sealing surfaces.
  • Better lubricant retention - The grooves on the inside and outside diameter of these rings retain lubricant thereby lowering friction and extending packing life.
  • Saves space, reduces cost - One Multiseal® low friction seal can replace two U-Cups in many applications.
  • Less force, better seal - Lower breakaway force and reduced operating pressures make them ideal in reciprocating applications.
  • The right fit - Multiseal® low friction seals will fit in standard O-Ring grooves
