Sealing packing and piston ring are key parts that affect the reliability of compressor operation.

The main features of the PEEK (PES) non-metallic piston ring and sealing packing developed by our company are:
1. High temperature resistance, high pressure resistance (pressure difference), wear resistance, self-lubrication, long service life, more than 5 times the service life of alloy cast iron.
2. It meets the special requirements of micro-oil, oil-free, high-temperature, and high-pressure reciprocating compressors for sealing, small cylinder wear, allowing less oil lubrication, and extending the service life by more than 5 times.
3. Piston damage will not damage the cylinder and piston.
4. Improve the overall maintenance-free cycle of reciprocating compressors.
