About this seminar

In this seminar we will not only cover how O-ring installation spaces should be designed, but also why this should be the case and how to evaluate deviations. In addition, low and high temperature limits of O-rings as well as realistic service life expectations are discussed. Finally, we will provide many important application advices for different applications.

Please note that all open seminars are held in German.
For English seminars please contact us.

MORE INFORMATION

THE O-RING PRÜFLABOR RICHTER

The O-Ring Prüflabor Richter specializes in services designed to ensure a safe use of elastomer seals and technical moldings and has been accredited according to DIN EN ISO/IEC 17025 since 2002. In addition to numerous services, we also offer the performance of failure analyses, which we have carried out on more than 2000 cases to date.

Our gained experience is shared in seminars, in-house seminars and consultations. Since the laboratory was founded in 1996, more than 2000 companies have already taken advantage of these services.

INSTRUCTOR DIPL-ING. BERNHARD RICHTER

After he graduated with a degree in mechanical engineering from the University of Stuttgart, Bernhard Richter was employed by one of the world’s leading sealing manufacturers for more than ten years, seven of which were spent as Head of Applications Engineering of the European O-Ring Division. Soon after, he founded the O-Ring Prüflabor Richter in 1996 and has since passed on his knowledge in seminars throughout the year.

His ability to comprehensively understand complex correlations is particularly appreciated. Furthermore, he is not afraid to provide the user with clear decision criteria. He has been an expert in the ISO Working Group on O-Ring Standardization (ISO 3601) for more than ten years and is well known for his numerous publications.

IN-HOUSE SEMINARS

We also offer individual designed seminars in English according to the needs of our customers.
