Materials and finishes
Selection and application
The circular wire section differs from flat sheet rings. End geometry, wire diameter and seat geometry must match the specific application, particularly for piston-pin retaining rings.
Other materials and finishes are available on request. Configuration and supply are confirmed against the specific enquiry.
