Product Description

GDK  PC 71 CYL Kit for Excavator Seal Kit

O-ring refers to the section of the "O" shaped rubber ring.It is one of the most widely used hydraulic and pneumatic transmission systems.Mainly used for mechanical parts in static conditions to prevent the leakage of liquid and gas medium.In some cases, the O-ring can also be used as a dynamic sealing element for axial reciprocating and low-speed rotating motion.It has the advantages of simple structure, convenient installation, low cost, easy maintenance and various materials.Can be used as oil, water, gas and other fluid sealing use.According to different conditions, different materials can be selected to adapt to it. 
From the sealing principle, O type seal is a kind of extrusion seal, extrusion type seal basic working principle is to rely on the elastic deformation of the seal, the contact pressure on the sealing contact surface, the contact pressure is greater than the internal pressure of the sealed medium, there is no leakage, otherwise leakage occurs.
