O-Ring Shelf Life

Shelf LifeThe information in ARP 5316, and the chart below, is intended to be utilized by those organizations who do not already have specific recommendations for the control of elastomeric seals. It should be noted that the packaging of the elastomeric seals prior to assembly into a product is an integral part of the controlled storage procedure. It provides a positive means of product identity from the time of manufacture, to the time of assembly.

The data shown here are shown as an engineering guide only and should not be used for the purpose of establishing performance limits. These values were obtained using established standard test procedures and are believed to be reliable. However, due to the variables that may be encountered in actual use, it is always advisible to test the material under actual service conditions before specification.
