Gasket Material Selection Guide

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.
