The guide will assist you in gasket material selection, gasket design and gasket application. Selecting the right gasket design and material is critical to the effective operation of a reliable joint. It involves taking into account a wide variety of application parameters such as function, temperature, fluid or gas, pressure, UV & Ozone, EMI/RFI requirements and other considerations such as FDA, NSF or WRAS requirements.
