This piston seal is characterized by the following properties:

  • Due to the application-optimized geometry and materials, it can be used with both oiled and oil-free compressed air (after assembly lubrication).
  • Good sealing effect with the smallest installation conditions.
  • Good wear resistance.
  • Low stiction and low dynamic friction due to the small construction.
  • Smooth running thanks to optimal lubricant-preserving geometry.
  • Easier installation.
  • High temperature resistance with a suitable choice of materials.
  • Excellent media resistance with suitable material selection.
  • Installation in closed installation spaces.

There are a number of materials available for this and other seals. Each specially developed for the requirements of pneumatic systems. In addition to low friction and low wear, these are also characterized by a very long service life. From this wide range, you can choose the right material for every requirement and application. PET Seals generally only uses materials from European or American suppliers.

High efficient thermal solution for modern Telecommunication and other Applications

The high-speed processing capacity of big data required by datacenter technology puts forward higher requirements for system thermal management. Excellent thermal management has become the key to accelerate computing and smooth the data processing.

Integrating the technical advantages and extensive experience of various industries, we have successfully supplied two-phase liquid cooling such as vapor chamber and heatpipe in our customers’ data processing infrastructure.


Interested to see our case study of different designs in an in-dept test?  We have determined a cost-effective 200W solution for our customer. Based on same power consumption and similar air flow, both heatpipe solution and vapor chamber (VC) solution are better than full copper cooler by 16%.  


Whilst CEV addresses the thermal issue occurred in the data processing, our customer can efficiently focus on conquering complexity of data processing and handle specific workloads such as analytics and artificial intelligence and related areas such as machine learning and deep learning.

We are ready to take this on together with our customers and being part of this 5G era!
