Vulcanized O-Rings are best suited for static applications where the seal is not exposed to dynamic motion or situations where standard O-Rings are not feasible. They are made by cutting O-Ring cord stock to the desired length and vulcanizing the cut edges, creating a strong bond. Common applications include:

  • Static Sealing: Ideal for applications without moving parts, ensuring a reliable seal.
  • Prototypes & Small Runs: Suitable for prototypes and small quantity runs, eliminating the need for expensive tooling.
  • Visual Inspection: Every O-Ring is visually inspected, with options for PI Taping and Olypsys® Measurement Verification CofC for sizes under 48” OD.
