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.


Manoy­Coat® – Anti-fric­tion coating
Manoy­Coat® coated O-rings offer spe­cial assembly and dis­as­sembly advant­ages due to their anti-fric­tion prop­er­ties. For auto­mated assembly, the coat­ing provides smooth feed­ing. Some of the coat­ings are also suit­able for dynam­ic applic­a­tions. FIND OUT MORE >
