Know the uses of the Caterpillar oil seal and PTFE/VITON oil seal

A Caterpillar oil seal is renowned for the effective prevention of the seepage of lubricating oil in mechanical equipment. These devices work resourcefully by closing the spaces between the static and dynamic components of the equipment. Oil seals are referred to as rubber oil seals, dirt seals, or oil gaskets, as well.

Caterpillar oil seals are available with the highest quality as well as with the most durable construction. These features make them more useful and reliable in a variety of sealing applications, including in housings and gearboxes. These oil seals are capable of preventing the leak of non-pressure grease and fluids, as well.

Normally, a shaft is rotating inside a bore or housing. There should be some clearance between the bore and the shaft due to friction. The job of the Caterpillar oil seal is to stop any type of the inside fluid from overflowing the clearance between the shaft and housing. The seal may be used to prevent exterior materials, as well, such as grime, from approaching through the clearance.

Some of the different types of oil seals you can find online include:

·         General Purpose High Performance Oil Seal

·         Rotary V-Seal

·         Rubber Fabric Oil Seal

·         PTFE Lip Oil Seal

·         PTFE Metal Case Oil Seal

·         PTFE O-Ring Energised Oil Seal

·         PTFE Spring Energised Oil Seal

The Caterpillar oil seal will usually consist of three essential components, such as the sealing part, the metal casing, and the spring. The job of the sealing part is to stop the fluid from seeping out between the housing and the shaft. The metal casing will provide the seal with rigidity as well as strength while it is being detained in the recessed groove or bore. The spring plays a vital role in making the sealing part more effective. Therefore, you need to choose the oil seal according to the environment in which the seal will work.

A PTFE/VITON oil seal refers to two types of oil seals, such as PTFE oil seal and VITON oil seal. Although they are used largely for the same purpose, each of them differs in their materials, structure, applications, and elasticity.

A VITON oil seal uses an artificial rubber and fluoropolymer elastomer, known as Viton. It is mostly used in seals, O-rings, and other molded products. When it comes to a PTFE oil seal, the seal is polymerized from a kind of plastic, known as tetrafluoroethylene.

Although a PTFE/VITON oil seal is used in a huge range of applications, a PTFE oil seal is used in more applications, such as medical equipment, chemical machinery, electronic appliances, as well as in other fields. The PTFE oil seal is also used in areas where rigidity as well as firmness in the temperature range is required. This is for the reason that the plastic material will exhibit a solid state. However, the Viton oil seal is largely used only in the sealing field.

Even if a great deformation happens in the Viton under the action of an outside force when the outside force is released, the original form can be reinstated and the flexibility is good. Therefore, Viton oil seals are considered more flexible than PTFE oil seals.
