Gaskets used in pharmaceutical processing equipment have to do more than create a reliable seal. Depending on the application, they may be exposed to aggressive process media, repeated cleaning and sterilization cycles, elevated temperatures, pressure changes, and strict contamination-control requirements. This combination makes gasket selection particularly important. A material may offer excellent chemical resistance but perform poorly under repeated steam sterilization. Another may withstand the operating temperature but be unsuitable for product contact or the cleaning chemicals used between batches. Selecting the right gasket requires looking at the complete operating environment rather than any single material property. Understanding the factors...

A gasket can create a reliable seal when first installed, only to begin leaking months or even years later. When that happens, it's easy to assume the gasket has failed or the flange bolts have loosened. In many cases, the real cause is less obvious: gasket creep relaxation. Over time, some gasket materials gradually deform while under constant compression, reducing the sealing stress needed to maintain a leak-tight joint. As that sealing stress decreases, the likelihood of leakage increases, particularly in applications involving elevated temperatures, pressure fluctuations, or extended service intervals. Understanding how gasket creep relaxation occurs can help maintenance...
