APPLICATIONS

The X‑ring is a con­ti­nuous, seam­less vul­ca­ni­zed ring with a spe­cial pro­fi­le which is deri­ved from four O‑rings arran­ged in a squa­re cross-sec­tion. The par­ti­cu­lar advan­ta­ge of the X‑ring is that it can­not roll or twist. The squee­ze requi­red to main­tain an effec­tive seal is also rela­tively low.
The X‑ring is used in mecha­ni­cal and auto­mo­ti­ve engi­nee­ring, pre­fer­a­b­ly as a sta­tic radi­al or sta­tic axi­al seal. Other app­li­ca­ti­ons are for line­ar or rota­ry moti­on of plun­gers, pis­tons, tap­pets, dam­pers and val­ve, bea­ring and pis­ton rods, etc.

CHARACTERISTICS

  • For wide pres­su­re and tem­pe­ra­tu­re ran­ges 
  • Wide ran­ge of fluids 
  • Space-saving 
  • Metal-to-metal con­tact pos­si­ble in flan­ge seals
  • Does not roll or twist in the groo­ve
  • Simp­le and effec­tive seal solu­ti­on for sta­tic and low dyna­mic app­li­ca­ti­ons
  • Also avail­ab­le in a PWIS-free ver­si­on (free of any sub­s­tan­ces that inter­fe­re with paint wet­ting)

TEMPERATURE RANGE

From ‑60 to +200 °C

but depen­dent on the X‑ring mate­ri­al in each case.

MATERIALS

X‑ring elas­to­mer

  • FKM
  • NBR
