O-Ring 21 x 2.5 mm

The Dal Soggio 1P.ORM21X2_5 O-Ring 21 × 2.5 mm is a replacement sealing component intended for use within compatible Dal Soggio suspension systems.

O-rings are used throughout suspension assemblies to create a hydraulic sealing interface between mating components, helping retain suspension fluid and maintain the pressure or circuit separation required for correct suspension operation.

This replacement seal is identified by its nominal 21 × 2.5 mm size and should be installed only where this exact O-ring specification is required.

During suspension servicing, O-rings should be inspected for flattening, cracking, cuts, deformation, hardening, or other signs of deterioration. Replacing worn or damaged seals helps restore effective sealing and supports reliable hydraulic operation.
