Silicone Flange Gaskets
A silicone flange gasket is made of silicone rubber that does not lose flexibility at very low and high temperatures. Being odourless and tasteless, it can be made in food-grade qualities.
A similar manufacturer catalogue gives −40 °C to +177 °C for silicone gaskets. It is used on hot air, drying, oven and food process lines; it is not suitable for high pressure and steam.
Main Applications
- Hot air and drying ducts
- Ovens and heat-treatment equipment
- Food and beverage process lines
- Cold store and freezer connections
- Laboratory and pharmaceutical equipment
