Rubber Gasket Seals in Electronic Assemblies

The basic reason for making use of rubber seals is avoiding fluid leakage between two joined surface areas. These are generally mechanical seals which are utilized in fixed as well as dynamic securing applications. Rubber seals, made from natural rubber or synthetic rubber, are used in numerous markets such as automobile, aerospace, building and construction etc. These seals are commonly taken on in different applications due to attributes like resistance to aging, fire retardation capability etc

. Rubber Seals Designs

There are various varieties of O ring manufactures such seals offered on the market on the basis of their styles, products, use and also applications. There are 3 prominent designs of these seals and each design has its distinctive cross section. Let us discuss these designs listed below:


As the name suggests, these are rounded designed, in the form of O or a doughnut. It has the capability to do a sealing activity by flawing to take the shape of the tooth cavity as well as can easily match it. It can be a static or a dynamic seal. In fixed sealing, there is no or little activity between the mating surfaces. In vibrant instances, a family member activity is seen in between the breeding surface. O ring has basic installing demands.


This design is in the shape of the letter-X and for this reason referred as X-rings. Sometimes, it is additionally called Q-rings. Thought about to be a better alternative to O-rings. Made use of mostly in rotary seal applications. X rings provide double-closing action. They have a four-lobed configuration which protect against the seal from being twisted. With two locations to be sealed, they require much less contortion to supply a reliable sealing.

Square Rings

These are seals with square random sample. Made from all-natural or synthetic rubber, these are used primarily in high pressure gasketing functions. Square rings are made use of in place of similar sized O-rings or other shaped seals. They are optimal for static applications but except dynamic applications. Some fundamental advantages of square rings are managed surface area smoothness, better elasticity, correctly created sides, and exact hardness.

U-cup Seals

Another prominent design of rubber seal is u-cup seals. They are primarily used for signing up with rods or rams. With little gland rooms, they come to be all the more best. With U-shaped cross sections, self securing is possible for both their within as well as outside diameters. There are three ranges of such seals.
