Toughgask Reusable PTFE Encapsulated Stainless Steel Reinforced Gasket
Toughgask reusable gaskets can be used in nearly all applications to seal metallic flange joints. They are far superior and cost effective compared with other designs such as envelope gaskets as they are reusable many times. Their design is extremely robust and they are very easy to install.
The Toughgask gasket offers superior performance than a standard virgin PTFE gasket as its inherent stainless steel core prevents cold flow of the PTFE which can lead to joint failure.
Due to the use of PTFE with its universal corrosion resistance the gasket can aid greatly with site standardisation being suitable for a varied range of applications across site.
Lined piping systems do not require gaskets to seal between the flange joints, the PTFE / PFA flange faces provide the seal. However if the specification state that gaskets are required then we recommend our FluoroGask PTFE gasket.
