Sealing in Difficult to Seal Fluid Handling Applications

The fundamental factor for making use of rubber seals is preventing liquid leak between 2 signed up with surfaces. These are essentially mechanical seals which are utilized in static along with dynamic sealing applications. Rubber seals, constructed from natural rubber or artificial rubber, are made use of in different markets like auto, aerospace, building etc. These seals are widely adopted in different applications due to features like resistance to aging, fire retardation ability etc

. Rubber Seals Layouts

There are various varieties of such seals readily available in the marketplace on the basis of their layouts, materials, usage and applications. There are 3 preferred layouts of these seals and also each layout has its unique cross section. Let us go over these designs below:


As the name recommends, these are round shaped, in the form of O or a doughnut. It has the ability to do a securing action by flawing to take the form of the cavity and also can easily fit into it. It can be a static or a vibrant seal. In static securing, there is no or little motion between the mating surfaces. In vibrant cases, a loved one activity is seen in between the mating surface area. O ring has easy placing demands.


This layout remains in the shape of the O ring manufactures letter-X and also hence referred as X-rings. At times, it is likewise called Q-rings. Considered to be a much better choice to O-rings. Utilized mainly in rotary seal applications. X rings offer double-closing activity. They have a four-lobed arrangement which stop the seal from being turned. With 2 areas to be sealed, they require much less contortion to provide an efficient sealing.

Square Bands

These are seals with square random sample. Made of natural or synthetic rubber, these are used mostly in high pressure gasketing functions. Square rings are made use of in place of similar sized O-rings or other molded seals. They are suitable for fixed applications yet not for vibrant applications. Some fundamental benefits of square rings are managed surface area level of smoothness, better elasticity, properly created sides, and also exact hardness.

U-cup Seals

An additional preferred style of rubber seal is u-cup seals. They are mainly used for signing up with rods or rams. With small gland rooms, they come to be even more best. With U-shaped sample, self sealing is feasible for both their within and also outside sizes. There are three selections of such seals.
