O-RING TOLERANCES Our catalogue specifies sizes and tolerances for Nitrile 'O' Rings manufactured from standard moulds. Where 'O' Rings in higher shrinkage materials are manufactured from standard tooling e.g. silicone and fluorocarbon, etc., increased lower tolerance limits may apply. In very many instances, our factory has produced moulds specially for the high shrinkage materials and therefore tolerance compensation may not be required.  Please check with our Technical Department.
