It must be remembered that a seal is much more than a spacer which can take all types of abuse and still function as intended. Generally, a gasket is placed between two surfaces in order to prevent leakage. Even though that is a static piece of material and is generally not subjected to constant mechanical action or chemical exposure, it must, nonetheless, meet several criteria to be able to perform its function.

What is the Best Way to Store Gaskets?

Most gasket storage practices are rarely optimal or even satisfactory. What is the best way to store gaskets and how can we improve the way we currently store them?

Although many gaskets or gasket materials from which they are cut can be used safely after storage for many years, ageing will have a distinct effect on the performance of certain types of gaskets or those materials. Primarily, this is a concern with materials which are bonded with elastomers. They in general should not be used after about 5 years from the date of manufacture. If required, they shall be used only after careful inspection. Gaskets or materials with elastomeric binders will inevitably deteriorate over time, and even more quickly at higher ambient temperatures. Degradation is also catalysed by intense sunlight.
