O-rings are circular sealing elements with circular cross-sections, and are mainly used in static applications. The sizes are specified by the inside diameter and the cross section diameter. Our O-rings are manufactured according to metric and imperial international standards such as AS 568B, DIN ISO 3601 and JIS. Custom sizes of almost any dimension are possible, such as miniature O-rings, special O-rings with large dimensions and continuously molded and spliced cord. We utilize O-ring compounds formulated to meet the most stringent industry standards, including FDA, USP, KTW, DVGW, BAM, WRAS (WRC), NSF, Underwriters Laboratories (UL), Aerospace (AMS) and many customer-specific requirements.
