Structural Aspects of Sealing Profiles

The basic factor for making use of rubber seals is avoiding liquid leakage in between 2 signed up with surfaces. These are generally mechanical seals which are made use of in fixed in addition to vibrant sealing applications. Rubber seals, made from all-natural rubber or artificial rubber, are utilized in numerous industries such as automotive, aerospace, building and construction etc. These seals are extensively embraced in numerous applications as a result of features like resistance to aging, fire retardation capacity etc

. Rubber Seals Layouts

There are different varieties of such seals readily available in the market on the basis of their layouts, products, use as well as applications. There are three prominent designs of these seals and also each design has its unique random sample. Allow us discuss these designs listed below:


As the name suggests, these are round designed, in O ring manufactures the form of O or a doughnut. It has the capacity to do a securing action by warping to take the shape of the tooth cavity as well as can conveniently fit into it. It can be a fixed or a vibrant seal. In fixed sealing, there is no or little motion in between the mating surfaces. In vibrant situations, a family member movement is seen between the mating surface area. O ring has easy placing demands.


This layout is in the form of the letter-X and thus referred as X-rings. At times, it is also referred to as Q-rings. Considered to be a far better alternative to O-rings. Used mainly in rotating seal applications. X rings supply double-closing action. They have a four-lobed setup which protect against the seal from being twisted. With 2 areas to be sealed, they call for less deformation to offer a reliable securing.

Square Bands

These are seals with square random sample. Constructed from all-natural or synthetic rubber, these are made use of generally in high stress gasketing features. Square rings are used instead of comparable sized O-rings or other shaped seals. They are suitable for fixed applications however except vibrant applications. Some fundamental benefits of square rings are regulated surface level of smoothness, far better flexibility, correctly created sides, and also exact hardness.

U-cup Seals

An additional preferred design of rubber seal is u-cup seals. They are mostly used for joining rods or rams. With little gland spaces, they become all the more excellent. With U-shaped random sample, self sealing is possible for both their within as well as outside diameters. There are three selections of such seals.
