Seals for the industry - since 1988

Fascinated by pneumatics and hydraulics, Gernot Kofler founded the company Kofler - Dichtungen in 1988, with the aim of providing the best seals for Tyrolean industrial and construction companies. 
The quality of the Kofler seals and gaskets has also proven itself internationally.

Kofler - Dichtungen unser Markenversprechen

Our understanding of quality - your seal

We start each production with the aim of achieving the longest possible service life for the seal. "If the planning is right, the product is right," is our credo. Because only if the customer receives the right seal can a long service life be expected. This quality begins with the procurement of raw materials and semifinished products.

The selected semifinished product is processed by our CNC experts. The finished gasket undergoes several quality controls during the manufacturing process. Once the seal has been released, it leaves our company neatly packaged and accurately labelled towards the customer.
