How to choose the material for a rubber gasket?

Choosing the right rubber gasket material is just as important as defining its dimensions. A gasket can fit perfectly in its housing.

Flat rubber gaskets are sealing elements designed to ensure a watertight seal between two flat surfaces, typically in flanged joints. Their function is to prevent leaks of fluids or gases under pressure and to compensate for surface irregularities, vibrations, or thermal expansion. Manufactured from elastomers such as NBR, EPDM, FKM, CR, or NR, these gaskets offer flexibility, chemical resistance, and excellent elastic behavior under compression. They are widely used in sectors such as fluid handling, HVAC, water treatment, food processing, and the chemical and petrochemical industries.
