In this guide, we will dwell deeply on oil seals and discuss everything that you need to know, such as what it is, how it works, why it fails sometimes, materials used in making it, factors to consider in choosing the right one for your application, and so on.
Installation of the oil seal
Installation
Polytetrafluoroethylene
Chemical resistant
Low coefficient of friction poor elastic properties not wear resistant if used by dynamic applicationsOil seals require sufficient time to solidify and cure. Premature use of equipment with newly installed oil seals can compromise the integrity of the oil seal and may damage your machine. Refer to the supplied instructions for the time frame allocated for the seal to cure.

- In addition to their chemical resistance, cork rubber gaskets also have excellent thermal stability
- Additionally, the gasket acts as a barrier to prevent the entry of contaminants such as dust, dirt, and moisture into the engine, which can cause damage or corrosion to engine components.
- Replacing a car oil gasket is a specialized task that requires precision and expertise
- FKM TC oil seals are also highly durable and long-lasting, thanks to the robust nature of the FKM material. They have a low compression set, meaning they can maintain their shape and sealing ability over long periods of use
fkm tc oil seal. This durability helps to reduce maintenance costs and downtime, making FKM TC oil seals a cost-effective sealing solution for many industrial applications.

9 Factors for Selecting Oil Seals
Oil seals with outer metal cases may include finishes or treatments applied to the outer edge to aid in rust protection, identification, and sealing of scratches or imperfections in the housing bore. Common finishes applied to the outside edge of metal O.D. oil seals include plain (a bonding agent of usually a yellowish-green color), a color-painted edge, and a grinded-polished edge.
Bauerle and Bruhnke7 found that aeration reduces the effect of oil additives on fluoroelastomer properties. Some of their data is reproduced in Fig. 14.4,5 showing the effect of aeration of an SF-grade 5W30 oil on the retention of elongation of a VDF/HFP copolymer (FKM-E430), a VDF/HFP/TFE terpolymer (FKM-B600), and a VDF/PMVE/TFE fluoroelastomer (FKM-GFLT). The HFP-containing polymers show much better retention of properties with aeration.

Although it does have a higher tensile strength and longer wear times than other materials, it is recommended to be used in dry-running applications sparingly or intermittently.


a) The shaft on which the oil seal is to be mounted should be ground with the surface finish or surface roughness between 0.2 to 0.8 Microns. It is best for the shaft to be hardened atleast to 40 – 45 HRc in order to prevent groove formation on the shaft due to the pressure exerted by the spring.
PTFE is special in that a pre-tensioned spring is not required. This is because the material returns to its original shape when heated, also known as the shape-memory polymers (SMPs) effect. These oil seals are also supplied as integrated parts, where it only needs to be installed as one component.
