Product detailed description

This is a seal suitable for both static and dynamic sealing. X-rings were created to eliminate the disadvantage of O-rings – their twisting in the groove. X-rings have an approximately square cross-section with annular grooves. The groove dimensions for X-rings correspond to those of standard O-rings, so they are interchangeable. As with O-rings, X-rings are defined by inner diameter (d) and thickness (h). The advantages of X-rings are mainly their better suitability for rotary sealing, greater stability in the installation space and lower radial preload in the groove. This reduces friction and wear and extends the service life of the seal.

X-rings can be used to seal a groove in static sealing up to a pressure of 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 classic materials, mainly 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.
