Dust Seal vs Oil Seal Understanding the Key Differences and Applications

What are High Pressure Rotary Seals?

   Before initiating the replacement process, accurately identify the sealing components requiring replacement. This includes seals, gaskets, O-rings, and any other relevant parts.

Wiper oil seals, commonly referred to as lip seals or simply oil seals, are mechanical seals used to keep lubricants in and contaminants out of machinery. They are typically made from durable materials such as rubber or elastomers, designed to withstand high pressures and temperatures. The primary function of these seals is to maintain a barrier that prevents the escape of oil, while also preventing dirt, dust, and other contaminants from infiltrating the system.

Oil seals are designed to create a barrier between the moving parts of a machine and the external environment. They are typically made of rubber or elastomeric materials that are resistant to oil, temperature changes, and wear. The primary function of an oil seal is to retain lubricants within the system and prevent the ingress of contaminants such as dirt, water, and debris.
