What are the differences between gasket materials?
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.
PTFE: PTFE Teflon brewery gaskets have the widest temperature range (-100ºF to 500ºF) and are also the hardest making them ideal for locations that need to rotate against each other like racking arms. (Never rotate or loosen a connection that is holding back hot liquid!) Being hard, they are somewhat more difficult to get a good seal. PTFE brewery gaskets are solid white.
DSO Fluid Handling Sanitary Tri-Clamp gaskets for all applications in the food, beverage, dairy, and pharmaceutical processing and bioscience industries.
All gasket compounds meet the FDA criteria for food and beverage applications, USDA and 3A. Most sanitary gasket compound formulations have also been tested and certified to USP Class VI 87 and 88 standards for pharmaceutical and multiuse applications.
