BASIC GASKET APPLICATION GUIDE & MATERIAL SELECTION Application / Function Because gaskets are generally low cost and appear to be simple, the criticality of their role in a device is often overlooked. They usually don't garner much attention until there is a problem with an application or if there are high maintenance cost to service the gasket.

Vulcanized Rubber Rubber stoppers and valves. Charles Goodyear was an American inventor who dedicated his life to rubber, a substance initially produced from sap from a tree, and now primarily artificially synthesized. Natural rubber products would become brittle in the cold winters and melt and deform in the hot summers, making rubber an .
One sample was seen by famed English rubber pioneer Thomas Hancock, who had been trying for 20 years to make weatherproof rubber. Hancock noticed a yellowish sulphur "bloom" on the Goodyear sample's surface. With that clue, he reinvented vulcanized rubber in 1843, four years after Goodyear.
