Profile: Trelleborg Sealing Solutions Germany GmbH is a supplier of sealing solutions. Our range of products includes O-Rings, hydraulic seals, rotary shaft seals, oil seals, static seals, pneumatic seals and mechanical face seals. We are ISO 9001:2000 and ISO/TS 16949:2002 certified. Piston seals are always fitted with an interference fit. In order to avoid damage during installation, lead-in chamfers and rounded edges must be provided on the cylinder barrel. If this is not possible for design reasons, a separate installation tool must be used. The minimum lead-in chamfer depends on the profile size of the seal. The Turconr AQ-Sealr is a double-acting seal consisting of a seal ring of high-grade modified Turconr material, a X-ring seal, and an O-ring as energizing element. The Turconr seal ring and the X-ring seal together assume dynamic sealing function.
