What are the differences between gasket materials?
Silicone: Silicone brewery gaskets have a very wide temperature range of -58ºF to 446ºF making them suitable for a wide range of applications and great for home brewing locations where they will be near flame or in heat wash. They are very flexible and relatively soft making them easy to work with and seal. They can get gummy over time when used with strong acids and caustics in commercial applications. Silicone brewery gaskets are translucent clear.
EPDM: EPDM brewery gaskets have a narrower temperature range than silicone (-30ºF to 300ºF) but stand up to stronger acids and caustics than silicone making them more desirable in commercial applications and excellent for home brewery applications. EPDM brewery gaskets are relatively soft, easy to seal and probably the best all around choice for any application that doesn't need to live close to a flame source.
