Choosing the right rubber sealing material is not just about performance — it’s about ensuring the long-term stability and reliability of your equipment. As an experienced Chinese exporter of rubber seals like O-rings, oil seals, bonded washers, and PU dust wipers, we’ve helped clients across industries make the right material decisions. Here are the top …
Proper storage conditions must be maintained to ensure the physical and chemical properties of rubber seals (e.g., O-rings) remain intact during long-term storage. Compliance with international standards such as DIN 7716, ISO 2230, and DIN 9088 is critical for preserving dimensional stability, cleanliness, and performance. Below are the key storage principles and shelf-life recommendations: Storage Conditions Temperature Ideal …
The piston of the pump truck is in direct contact with concrete, requiring sealing and abrasion resistance. When we find that the water in the tank is muddy or there is concrete, we should realize that the piston may be seriously worn. We need to check the piston. If the piston is worn, we need …

1. Speed Speed is a necessary factor that should be considered when selecting seals. We divide the speed into three levels:Low speed 0 ~ 0.8m/s;Constant speed 0.8 ~ 2m/s;High speed 2 ~ 5m/s; The limit of speed is limited by temperature because the increase in speed is ultimately attributed to the increase of lip temperature, …
The production process of the oil seal is basically composed of the following six sections: rubber preparation, mold preparation, skeleton preparation; Spring preparation, product vulcanization forming, after processing assembly section. Therefore, its process flows basic composition. 1. Rubber preparation section The main processes of this section are as follows:Raw material – factory inspection – batching …

Before learn how to improve the leakage of rubber seals, we should know some basic knowledge about this item: 1. The characteristics of rubber seal material: (1) Viscoelasticity The material of rubber seals is affected by temperature and time during deformation and deformation recovery, resulting in the stress relaxation and creep phenomenon of the material …
