Rubber Seals

Rubber seals are primarily composed of synthetic rubber materials, each offering unique properties suitable for different applications. Rubber seals play a crucial role in various applications, providing a barrier against external elements and controlling fluid passage.

Types of Rubber Seals:

O-Rings: These are one of the most common types of industrial rubber seals. O-rings rely on mechanical compressive deformation to act as a barrier between mating surfaces, restricting the flow of fluid in predetermined areas.
Radial Lip Seals: These seals are used in applications with lower pressure-velocity (PV) values relative to mechanical face seals. Radial lip seals handle considerable relative motion due to shaft/bore rotation or reciprocation^.

Elastomers (or rubbers) are used in mechanical seals to create positive pressure against surfaces, eliminating or controlling the leakage of liquids and gases while preventing the entrance of external contaminants.

Static Sealing: Occurs between adjacent surfaces with no relative motion (e.g., between the pump casing and cover).

Dynamic Sealing: Occurs between surfaces that are continuously or intermittently moving relative to each other (e.g., between the pump casing and shaft).

In mechanical face seals, elastomers provide secondary sealing between the seal faces and adjacent surfaces.

Prevents the ingress of contaminants (dirt, dust, water) into the system.
Retains lubricants (such as oil or grease) within the system.
Rubber seals are versatile and suitable for various industries, including automotive, aerospace, industrial machinery, and household appliances

Automotive engines (sealing crankshafts, camshafts, etc.).
Gearboxes, pumps, and other rotating equipment.
