ELRING brand Seal Ring are made from various grades of rubber. The selected raw materials affect the properties of the products. Elasticity provides a snug fit to the parts of the mechanism, which guarantees the sealing of the connection.

Rubber has average strength and durability, which is why structures made of it cannot withstand prolonged mechanical stress. This leads to leaks and makes them vulnerable to pneumatic and hydraulic systems. In addition to rubber, silicone rubber, polyurethane and other polymers with similar properties are used in production.

The seal ring functionality

Sealing elements are used in movable, fixed connections. Dynamic seal is used in the presence of rotary, oscillatory, reciprocating movements. The operating conditions determine the requirements for the properties of products, for example, the ability to recover after deformation. Even in static joints, this quality helps to ensure the reliability and tightness of the joint for a long time.
