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.

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.

An overview of the different standard types of oil seals and their main characteristics is shown below.
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.

Gasket Valve Cover: Selecting Quality Components
U-shaped silicone gaskets are versatile sealing components used in various industries for their resilience, flexibility, and resistance to extreme temperatures and environmental conditions. These gaskets are commonly employed in applications where a reliable seal is required, such as in automotive, aerospace, and industrial equipment. The U-shaped design allows for easy installation and effective sealing, making them suitable for a wide range of applications.
Most oil seals consist of some basic elements that configure their structure, such as the sealing element, the metal case, and the spring:
What Benefits Do Oil Seals Provide?
Its sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.

Many – too numerous to list, covering a vast range of designs, sizes, and materials suitable for a never-ending range of applications. Some designs conform to International Standards such as BS1399 and DIN 3760 for metric sizes and seal types, but the majority have been manufactured to suit particular applications – hence the enormous selection available. This blog is intended to assist in this selection and will consider seal type, materials, and sizes.
O.D. (outside diameter) surface The O.D. surface affixes the oil seal to the housing and prevents leakage , through the fitting area, of substances to be sealed, while excluding contaminants.
