What are some chemically inert alternatives to Viton gaskets?
I have a gasket that needs to be water proof and chemically inert. A resilient elastomer is needed because I need a watertight seal around tubing that punctures through the gasket. While Viton A does this nicely, it is not chemically inert and tends to shred when punctured, allowing tiny Viton pieces to escape during operation. I am looking for gasket material that is resilient like Viton, so that it can keep a seal around a tube that has punctured it. A chemically inert material would be preferred, so that it can be cleaned using a wide range of solvents. Any suggestions are appreciated.
