Rod seals are vital to maintaining an efficient hydraulic system, as they are responsible for both preventing fluid leakage from within a hydraulic cylinder and protecting it against dirt and other exterior contaminates.
Hydraulic seals come in a variety of shapes and sizes, but more importantly are specially developed to accommodate different cylinder speeds, temperatures, applications and materials.
Made to be placed in a groove or within a combination of rings to form a seal that prevents leakage in a hydraulic application, they are a critical component to keep machinery safe, secure and free from damage. 
Hydraulic Seal Materials
In order to maximise longevity and functionality in specific hydraulic applications, hydraulic seals are made from a wide range of materials, each with their own specific properties. Based on criteria such as operating temperature, chemical interactions, pressure and fluid types, manufacturers select the materials that can handle each environment best.
