Spare parts kits to replace friction pairing – quick and easy.

Extend the life of your compressor with a new head kit.

Compressors from Dürr Technik are equipped with high-quality head kits that are durable and offer a long life.

To ensure optimum performance and to prevent breakdowns it is recommended that the head kits (cup seal and cylinder bore) are replaced at regular intervals.

As compressor use is so specific it is not possible to give a fixed replacement schedule. However, below are some guidelines and recommendations for replacement based on the application. You can also watch our service videos to see how quick and easy the replacement can be.

If you would like us to define a replacement schedule for you, or if you have any questions then, please contact our service department.

What type of user are you?

A combination of different factors and the type of use will determine when it is time to replace the friction pairing.

Low use

e.g. in the medical field, e.g. clean laboratory: replacement after 6 years.

Medium use

e.g. 1-shift industrial operation, depending on environmental factors: Replace after 2.5-5 years.

Maximum use

e.g. 10 hours a day with 70% duty cycle as in fast food chains: Replace after 1.5-3 years.


These factors affect the life of the friction pairing:

Several factors determine the life of the friction pairing. The most critical factor is the number of operating hours, which is highly dependent on the specific application, is a critical factor in the wear of the components.
