Product: O-ring

O-rings are a large product group used in a wide range of applications. These applications include high temperatures, oil and fuel contact, chemicals and hot water. We offer O-rings that are manufactured to meet your expectations in most segments of the industry. The O-rings are round sealing rings that are defined by 2 dimensions, inside diameter d1 and ring thickness (cross section) d2.

Material: AU

AU rubber has excellent abrasion resistance thus can withstand wear and tear friction caused by mechanical parts as well as the effects caused by repetitive scraping or rubbing. AU also demonstrates excellent resistance towards oils and good ozone resistance. Their inherent resistance to oils means that AU components will perform well in applications with consistent exposure to fuel and oil, performing its intended function while in contact. The service temperature range of AU is limited to approximately -10 to +70ºC.
