Types of Hydraulic Seals

Hydraulic and Pneumatic Seals are moulded according to working temperature, cylinder speed, cylinder operating pressure, working application, and medium.

They are usually non-metallic, quite soft rings placed in a housing, or arranged in a mixture of rings creating a sealing unit. This is to separate or block liquid in applications that involve reciprocating motion. Hydraulic seals are crucial in machinery equipment. Their use is vital when it comes to enabling the transformation of liquid into linear motion.

Hydraulic Seals are generally made out of a variety of materials, including Rubber, PTFE, and Polyurethane (AU). Compatibility of the materials is decided upon the particular operating medium or restraints due to pressure, fluid type, temperature or chemical compatibility.

Static Hydraulic Seals are positioned in a housing where there is no motion involved, they are sealing only within their limited space.

Dynamic Hydraulic Seals are Rod Seals and Piston Seals. Rod Seals are exposed to the motion on their inner diameter along the rod or shaft of a hydraulic cylinder. However, Piston Seals are exposed to the motion on their outer diameter along the bore or tube of a hydraulic cylinder.
