Rubber seal is used to join or seal two systems or mechanisms together.
Rubber seals are ring-shaped component that are designed to obstruct or
limit the fluid leakage from a device. There are various types of seals used
in various applications that have constantly moving equipment, like for
example the rotating or reciprocating shafts and cylinders that form an
essential part of hydraulic and pneumatic systems including seals for
windows of cars. Rubber seals are seals made from both natural and synthetic
rubber.

Types of Rubber Seals
- Oil Seal: This is a very common type of seal. It is
used to retain oil and other lubricants in rotary applications and
prevent leaks. Many of these seals function with a flexible lip that rub
against the shaft or housing to prevent leakage by providing a tight
seal.
- Mechanical Seal: This seal is used in applications
that have a rotating shaft under a state of high temperature, pressure
and speed. The mechanical seals are used to prohibit fluid leakage for
mechanisms such as pumps, mixers, agitators and cryogenic seals.
- Rubber O-Ring: This belongs to a class o-rings that
are made from a synthetic rubber-like material called an elastomer. This
is a sealing ring that has a circular cross section which can be either
hollow or solid. The seal can be used as a secondary seal for many
mechanical seals.
- Balanced Seal: These seals are used to reduce the
effects of hydraulic pressure in the seal compartment.
- Bellows Seal: It is used as a formed or welded
bellows which supply a secondary sealing and spring loading.
- Bidirectional pressure Seal: This type of seal
uniformly seal as a result of pressure from both directions. It is also
known as "double balanced seal" or "reversible balanced
seal."
- Dynamic Seal: This seal is used to stop leakage
past components, when the components are in relative motion.
- Lip Seal: This is considered to be a versatile and
high-performance seal which is used for uniform, low-pressure sealing.
- Rubber Piston Seal: Rubber piston seals are used
for better grip, with specified engravings.
- Rubber Hydraulic Seal: Hydraulic seals are exposed
to hydraulic fluids and are designed for high-pressure dynamic
applications.
- Rubber U Seal: U-Seal, an integral part of
hydraulic and pneumatic systems, have a symmetrical lip profile with
chamfered sealing edges.
- Rubber V Seal: This is a type of axial seal for
shafts and bearings, which seal axially against a counterface. V seals
are very reliable and effective against dust, water and oil splash and
other media.
- Wiper Seal: The wiper seal is used to prevent the
ingress of dirt, dust and other foreign bodies, therefore extending the
working life of the rubber seal it is protecting.
Applications of Rubber Seals
There are many types of rubber seals used in industries for different uses.
Some of the industries that make use of these rubber seals include:
- Medical and pharmaceutical
- Waste disposal
- Aerospace
- Marine
- Food and chemical processing
- Automotive
- Military
- Nuclear and
- Pulp and paper mills
Application include pumps & valves, mechanical seals, hydraulic &
pneumatics cylinder, filter, actuators, motors, engine, lubricating System
etc.
