Quadrings (X-Rings)

4 LOBE SEALS FOR STATIC AND DYNAMIC APPLICATIONS

Quadrings, also known as X-Rings or four-lobe seals, are elastomeric sealing elements designed for applications that require higher performance than a conventional O-ring. Their “X”-shaped cross-section creates four sealing lips that distribute the contact pressure more evenly, reduce friction and prevent the seal from twisting during operation.
Thanks to their symmetrical design, quadrings can be used in both static and dynamic applications, offering excellent sealing performance in hydraulic and pneumatic cylinders, shafts, valves, pumps, actuators, industrial automation systems and a wide range of mechanical equipment.

Key features

Four-lip profile for more efficient sealing.
Lower friction than a standard O-ring.
Reduced stick-slip effect and breakout forces.
Excellent behaviour in reciprocating movements.
Suitable for low- and medium-speed rotary and oscillating applications.
Lower tendency to twist during assembly and operation.
Lubricant reservoir between the sealing lips, which improves service life.
Optimised contact-pressure distribution.
Static and dynamic sealing with the same geometry.
Available in AS568 dimensions and numerous additional metric sizes.

Available materials

At OSN we supply quadrings manufactured in a wide range of elastomeric compounds to suit different working conditions, temperatures and chemical compatibilities.

NBR (Nitrile) is the most widely used material for its excellent resistance to mineral oils, greases, fuels and hydraulic fluids, as well as offering great wear resistance and an excellent value for money. FKM (Viton®) is especially suited to high temperatures and aggressive chemical media, providing outstanding resistance to synthetic oils, aromatic hydrocarbons and numerous chemicals. For applications involving hot water, steam and atmospheric agents, EPDM is available, while for low temperatures or special applications, VMQ (silicone), CR (neoprene), HNBR, FFKM and other technical elastomers can be supplied on request.

We also offer materials with specific approvals for the food, drinking-water, pharmaceutical, chemical and oil & gas industries, as well as special formulations according to the requirements of each project.
