The shelf life of EPDM O-ring seals depends on their usage environment.

EPDM rubber has excellent oxidation resistance, ozone resistance, and chemical resistance, making it widely used in sealing and shock absorption applications such as automobiles, buildings, electronics, and medical equipment.

In a normal usage environment, the warranty period of the EPDM O-ring is about 10 years. In some special usage environments, such as high humidity, high temperature, and highly corrosive media, the shelf life may be shortened.

In addition, the shelf life of EPDM O-ring seals is also related to factors such as manufacturing process, material quality, and frequency of use. Generally speaking, high-quality sealing rings have a longer service life, while low-quality sealing rings may experience problems such as aging and cracking in a shorter period of time.

In order to extend the service life of EPDM O-ring seals, strict inspection and testing should be carried out before use to ensure that their quality meets the requirements. During use, the appearance, size, and performance of the sealing ring should be regularly checked, and damaged sealing rings should be promptly discovered and replaced. In addition, attention should also be paid to the maintenance of the operating environment, such as maintaining dryness, cleanliness, and avoiding prolonged exposure to adverse environments such as high temperatures and ultraviolet radiation.
