Product detailed description

This is a sealing element suitable for both static and dynamic sealing. X-rings were developed to eliminate the disadvantage of O-rings, which is their rolling (twisting) in the groove. X-rings have an approximately square cross-section with circular grooves.

The groove dimensions for X-rings correspond to those of standard O-rings, so they are interchangeable. Like O-rings, X-rings are defined by their inner diameter (d) and thickness (h). The main advantages of X-rings are their better suitability for rotary sealing, greater stability in the groove and lower radial preload in the groove. This reduces friction and wear and extends seal service life.

X-rings can be used to seal a groove in static sealing up to 5 MPa, with a back-up ring up to 40 MPa. For dynamic sealing, pressures up to 5 MPa apply, with a back-up ring up to 20 MPa. X-rings are made of common materials such as NBR (nitrile butadiene rubber) and FPM (fluororubber). However, they can also be supplied in EPDM, silicone or other rubbers. Like O-rings, X-rings are manufactured according to DIN 3770.
