Key factors affecting the performance of rubber sealing products.

2026-05-14
Latest company news about Key factors affecting the performance of rubber sealing products.

To ensure that the seal plays a positive role and avoid failure, the following points must be noted:
Material compatibility: Rubber materials must be compatible with the medium they come into contact with (oil, water, chemicals, etc.), otherwise swelling, shrinkage, softening, or hardening may occur, leading to failure.
Working temperature: Each rubber material has its applicable temperature range. Excessive temperature can accelerate rubber aging, become brittle, and lose elasticity; If it is too low, it will make the rubber harder and lose its sealing ability.

Pressure: Seals must be able to withstand the working pressure of the system, and special sealing structures with retaining rings may be required for high-pressure conditions.
Surface quality: The roughness, hardness, and flatness of the metal surface (such as shafts, holes) in contact with the seal are crucial. Rough or scratched surfaces can rapidly wear down seals, leading to early failure.
Installation quality: Incorrect installation (such as using violence, not adding protective covers, and not paying attention to cleaning) is a common cause of seal damage before being put into use.
