Oil-resistant rubber expansion joint has a longer service life than ordinary flexible rubber expansion joint.

Rubber Expansion Joints are also known as rubber expansion joints,Rubber Flexible Joint,Rubber Soft Joint,Rubber Flexible Expansion Joint,flexible rubber expansion Joint high-pressure Rubber Joints, rubber shock absorbers, compensators, and so on. They can be classified into three types based on connection methods: loose Flange, fixed flange, and threaded; and five types based on structure: single-sphere, double-sphere, reducing, elbow, and air pressure coil. These rubber joints are made of inner and outer rubber layers, cord fabric layers, and steel wire rings, which are first vulcanized into tubular rubber components and then combined with metal flanges or parallel connectors in a loose manner. This product can reduce vibration and noise, and compensate for thermal expansion and contraction caused by temperature changes, making it widely used in various piping systems.

I. Material Analysis of Oil-resistant Rubber Joints:
Oil-resistant rubber expansion joints are made of high-quality nitrile rubber, which has excellent oil resistance and is suitable for various oils, such as petroleum and lubricating oil.

II. Manufacturing Method of Oil-resistant Rubber Joints:
High-strength, thermally and cold-stable polyester cord fabric is used and plied at an angle to form an integral inner and outer rubber layer, creating a smooth and seamless appearance. The labels are also vulcanized and integrated with the product.

III. Price of Oil-resistant Rubber Joints:
Due to the higher material cost compared to ordinary rubber, oil-resistant rubber expansion joints are priced higher than commonly used rubber joints. When selecting rubber joints, users must choose the material based on the media they will be used in.
