Our service orientation is an integral component of our company´s philosophy. In this regard, we do not see ourselves as the classic average parts supplier, but rather as our customers´ partner.

From the application-technological consultation to the delivery, we work customer-orientated and provide our customers with our entire expertise as well as our best solutions.


Material Selection

A long tradition of experience with materials

We have been producing non-metallic gaskets for over 80 years.

Thanks to our successful business development, we possess very detailed and pronounced expertise about the advantages and disadvantages of the various materials. We will gladly share this knowledge with you.

Use our knowledge to select the correct gasket for the application in your products at an early stage.

Thanks to our close relations to the materials suppliers, we have played a part in many discussions about the further development of individual materials and today, we profit from these innovations for the benefit of our customers.

We will gladly give you a non-binding consultation up front.


 Process Management

Flexibility and promptness

An experienced team, our highly specialised tool manufacture, our excellent supplier contacts and our well-sorted storage as well as our specialised machinery create the foundation for our corporate concept:

we satisfy our customers´ wishes - flexibly and fast - with consistent high quality.

No matter whether collection of samples within 24 hours, regular just-in-time deliveries or reliable, quality-assured delivery of your order at the agreed time: we will assist you as a flexible and reliable partner.

Our organisational and financial independence enables us to continue on this path both consistently and without external effects.
