polyimide PI piston sealing ring pump piston ring

Among the various components of an oil-free air compressor, the PTFE piston skin bowl is a very important and fragile part, which is used to provide a mechanical sealing surface on the edge of the piston head of hydraulic cylinders and air cylinders. The quality of the piston ring directly affects the overall performance of the air compressor.For different applications of oil-free silent air compressors, PTFE composite bowls made of different materials should be selected.According to the requirements of different working conditions of customers, we can provide PTFE composite piston bowls with different materials.

Main Advantages
