Techné O-rings are primarily used in mechanical systems for static sealing in gas and liquid environments. They are also used for dynamic sealing, whether in translation or rotation.

Visibility-enhancement systems like video-camera aids without distance ranging and warning are not covered by this document.

We are committed to ensuring that our website is accessible to everyone. If you have any questions or suggestions regarding the accessibility of this site, please contact us.

Techné offers a stock range of O-rings with food approvals (FDA and EC 1935-2004) and drinking water (WRAS, ACS, CLP, UBA) that meet the technical requirements of specific markets and territories. Other certifications (BAM, DVGW Gas) are available upon request.

The manufacturing processes for O-rings vary depending on customer requirements. Depending on the quantity required, diameter, and chosen production site, Techné manufactures O-rings in its factories through injection or compression moulding, machining, or vulcanisation.

T-Surf® ensures the cleanliness of the O-rings and prevents contamination of the O-rings. At the same time, the original properties of the material are preserved.

The Techné O-ring is known for its efficiency, simplicity and various applications. The O-ring is an endless, circular sealing element with a circular cross-section. It is mainly used to seal gasses or liquids, especially in static applications.

The O-ring is a sealing element which, due to its simplicity and efficiency, is the ideal solution for a wide range of applications. Therefore, the O-ring can be found in many industrial sectors in specific applications:

MALSO systems use object-detection devices (sensors) for ranging in order to provide the driver with information based on the distance to obstacles. Although sensing technology is not addressed in this document, technology does affect the performance-test procedures set up in Clause 7. The current test objects are defined based on systems using ultrasonic sensors, which reflect the most commonly used technology at the time of publication. For other sensing technologies which will potentially emerge in the future, these test objects shall be checked and changed if required.

This document addresses light-duty vehicles, such as passenger cars, pick-up trucks, light vans and sport utility vehicles (motorcycles excluded) equipped with Manoeuvring Aids for Low Speed Operation (MALSO) systems. It specifies the minimum functionality requirements which the driver can generally expect of the device, i.e. detection of and information on the presence of relevant obstacles within a defined (short) detection range. It defines minimum requirements for failure indication as well as performance test procedures; it includes rules for the general information strategy but does not restrict the kind of information or display system.

Techné provides a variety of materials for O-rings that serve different applications. The choice of the right material allows the O-ring to withstand, for example, high pressure, high speeds and extreme temperatures. Techné's engineering department will be pleased to advise you on the choice of the right material for your specific application.
