Gaskets are used to prevent fluid or gas leaks by providing a barrier between two mating surfaces. The gasket must be able to maintain a seal under pressure and temperature changes. A number of different gaskets are available: pre-cut compression (flat or extruded style), formed-in-place, and cured-in-place. Some gaskets and gasketing can also be used to shield against electromagnetic and radio frequency interference (EMI/RFI).

A large range of gaskets can be supplied in various materials including CAF, nitrile, commercial rubber, neoprene, FPM, silicone, PTFE, polyurethane and many other materials.
