Possible sample provided: Explaining examples of O-ring defects and their countermeasures.
Name: We will introduce examples in the order of phenomenon, cause, and countermeasure. ■ Swelling: The rubber becomes soft, and the O-ring increases in size overall. The fluid used penetrates the rubber material → Change to a suitable rubber material. ■ Extraction: The rubber becomes hard, and the O-ring decreases in size overall. The plasticizer contained in the rubber material is extracted by the fluid used → Change to a suitable rubber material. ■ Permanent deformation: The O-ring is crushed and does not return to its original shape. The operating temperature is too high / The crush depth is too large → Change to a rubber material with good heat resistance / Review the groove dimensions or O-ring dimensions. ■ Overhang: The O-ring is torn either completely around or partially. It overhangs the gap between the groove and the mating surface and tears at the edge of the groove → Reduce the gap with the groove / Use a high-hardness O-ring or combine with a backup ring, etc. * Samples are available upon request.

basic information
【Other Examples of Issues and Countermeasures】 ■Tearing: The O-ring is partially torn. It is torn at the edge of the small hole in the cylinder / It is torn during installation due to sharp edges or screw threads → Design changes such as chamfering the hole / Using jigs for installation. ■Hardening: The O-ring becomes hard and cracks when bent. The operating temperature exceeds the heat resistance of the rubber material → Change to rubber materials with better heat resistance / Lower the operating temperature, etc. *Samples are available upon request.
