Static seals

Static seals reliably seal stationary machine parts and prevent the leakage of liquids and gases. Typical sealing elements include O-rings, back-up rings, X-rings, USIT rings, and valve seals. As an alternative to O-rings and back-up rings, the XS sealing ring offers high resistance to twisting, stability under pulsating pressure, and is particularly suitable for heavy-duty applications in cylinders and valves.
