Expanded PTFE Gasket

MVI represents the state of the art in gasket technology, a pre-compressed piping gasket produced wholly from multi-directionally expanded PTFE. It is 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. However, there are exceptions to this rule where joints are made and broken regularly, where lined equipment is joined to dissimilar materials or where gasketing has been selected as a site wide standard. MVI fulfils not only the gasketing needs of a lined piping system, but can also be used as the gasket of choice across all piping applications. Capable of meeting all types of flange standards, having almost universal corrosion resistance and handling a wide temperature, pressure and vacuum range they have countless applications. The multi-directional expanded PTFE improves the mechanical properties of PTFE making it highly conformable enabling 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, the gasket fits within the inner bolt circle (IBC) of the flanges providing as easy and safe installation. They are dimensionally stable and have a pre-compressed core increasing the rigidity and preventing cross contamination.
