Precompressed PTFE sealing gaskets for flanges
The state of the art in gasket technology.
Fluorogask is a pre-compressed piping gasket produced wholly from multi-directionally expanded PTFE. Specifically designed for use across the pharmaceutical and chemicals industries combining the corrosion performance and inertness of PTFE with a physical construction that produces an excellent gasket material.
PTFE and PFA lined piping systems do not usually require gaskets to maintain joint integrity. There are exceptions to this rule, however:
- Where joints are made and broken regularly
- Where lined equipment is joined to dissimilar materials
- Where gasketing has been selected as a site wide standard
Not only does fluorogask fulfill the gasketing needs of a lined piping system, it can also be used as the gasket of choice across all piping applications.
Near Universal Corrosion Resistance
Fluorogask have almost universal corrosion resistance and handle a wide temperature, pressure and vacuum range, are capable of meeting all types of flange standards and have countless applications.
The multi-directional expanded PTFE improves the mechanical properties of PTFE making it highly conformable, allowing it to achieve incredible levels of integrity across a comprehensive range of materials and flange types.
The gaskets are manufactured to conform to ASME B16.21, and fits within the inner bolt circle (IBC) of the flanges, providing easy and safe installation. They are dimensionally stable and have a pre-compressed core increasing the rigidity and preventing cross contamination.
They are both FDA and EU1935/2004 compliant for use across food and pharmaceutical manufacturing plants.
