O-Rings and Static Seals

O-Rings & Static Seals close joints in which the sealing surfaces do not move relative to each other. This category focuses on O-rings, associated accessories and other static seals, excluding products for rotating shafts or hydraulic movement.

An O-ring is a ring-shaped seal available in many forms and sizes. The correct combination of material and dimensions prevents leakage and poor application performance. ERIKS supplies rubber materials from NBR and EPDM to silicone and (F)FKM, including Viton® and Kalrez®.

O-rings are supplied for industrial applications and are also used in machine building, food processing, semiconductors and the petrochemical and chemical industries. For large batches of O-rings, flat rings and simple moulded parts, ERIKS offers a 100% inspection service; food-safe sealing requires a suitable material choice.

Select O-rings and static seals according to the application, required form and dimensions, and rubber material. Compare NBR, EPDM, silicone and (F)FKM with the joint conditions. For critical batches, determine whether additional 100% inspection is required and use suitable tools to fit or remove O-rings.

Key attributes are seal type, form, dimensions, rubber material and any 100% inspection of O-rings, flat rings and simple moulded parts.
