Mechanical Face Seals

The future climate guidelines and the goals of reducing global warming present new challenges. EKK's robust and high-pressure resistant gasket is suitable for R744 (CO2), R1234yf and R134a refrigerants. The low permeability rate was achieved through the intelligent sealing design and innovative rubber materials. The seals already meet future requirements today and make sustainable compressors possible.

Features

  • Rotary seal designed exclusively for car air-conditioning compressors.
  • Helps eliminate leakage from refrigerant gasses.
  • The sliding materials are made of two types of silicium carbide components that  are suitable for refrigerant gasses and refrigerant oil.
  • Easy-to-handle compact design.

This highly compact mechanical seal designed by EKK has been developed specifically for car air-conditioning compressors. The use of two types of silicium carbide components, which are suitable for refrigerant gasses and refrigerant oil, exhibit superb wear resistance and sealing performance. The mechanical seal is designed to hold a vacuum when the gas fills.

  • Rotary seal designed exclusively for car air-conditioning compressors.
  • Helps eliminate leakage from refrigerant gasses.
  • The sliding materials are made of special silicum carbide and carbon components suitable for refrigerant gasses and compressor.

New challenges are set by future regulations and the ambition to reduce global warming potential. EKK’s robust and high pressure resistant seal is suitable for R1234YF and R134A refrigerant. The low permeation rates achieved by a unique sealing design and innovative rubber materials can meet the future challenges today, enabling sustainable compressor applications.
