Dust seals are reciprocating seals used to prevent external dust from entering hydraulic cylinders. Common materials for dust seals include the following:

Rubber dust ring: Rubber dust ring is the most widely used material, which has good elasticity and plasticity, can adapt to various shapes and sizes of electronic device sockets, and also has a certain buffering and shock absorption effect.

Fluororubber dust ring: Fluororubber dust ring is a high-performance material with characteristics of corrosion resistance, oxidation resistance, high temperature resistance, chemical resistance, etc. It is widely used in chemical, aviation and other fields.

Polytetrafluoroethylene (PTFE) dust ring: PTFE dust ring is a sealing component made of polytetrafluoroethylene, which is widely used in various mechanical sealing applications due to its excellent chemical corrosion resistance, low friction coefficient, and good self-lubricating performance.

In addition, dust seals can also be made of other materials such as polyurethane (PU), polyamide (PA), etc., depending on the application environment and requirements. When choosing a dust ring, factors such as wear resistance, corrosion resistance, and high temperature resistance need to be considered to ensure that it can effectively prevent dust and pollutants from entering the hydraulic cylinder and ensure the normal operation of the equipment.
