Materials and finishes
Selection and application
Retention relies on the resilient action of the ring against the mounting surface, without a conventional groove. Mating-part material, hardness and finish are part of the application assessment. Holding force must be established for the specific variant.
Other materials and finishes are available on request. Configuration and supply are confirmed against the specific enquiry.
