Can bellows rubber ring be lubricated with oil?

In the installation process of bellows, a key question is often encountered: can bellows rubber rings be lubricated with oil? The answer is no. Although oil, butter and other oils have a certain lubricating effect, they will cause serious damage to the rubber ring, causing the rubber ring to age, harden, lose its original elasticity, and then affect the sealing performance and bury the hidden danger of leakage. Therefore, the bellows rubber ring cannot be lubricated with oil, but must use special lubricants.

From the perspective of material characteristics, bellows rubber rings are mostly made of rubber, and oil is an organic solvent. According to the principle of similar miscibility, the oil will chemically react with the rubber, accelerating the destruction of the rubber molecular structure. Long-term contact with the oil of the rubber ring, the service life will be greatly shortened, the sealing effect will be greatly reduced, which requires long-term stable operation of drainage, sewage and other piping systems, which is undoubtedly a huge risk.

So, what kind of lubricant is suitable for the bellows rubber ring? Generally speaking, neutral lubricants are the best choice, such as special rubber lubricants or high-concentration soapy water. These lubricants can not only play a good lubrication effect, help the rubber ring to install smoothly, but also will not cause damage to the rubber ring material, ensuring the durability of its sealing performance. For HDPE double-wall bellows rubber ring socket, it is also recommended to use special rubber lubricants. When applying, it is necessary to evenly cover the surface of the rubber ring and the contact parts of the socket port to ensure a smooth installation process and ensure the sealing effect.
