Gasket Tape
Very soft and conformable, this expanded PTFE gasket tape compresses into an extremely thin profile. Use it to create a leak-resistant seal in tight-tolerance applications, such as on precision machinery. This tape is chemically inert, except to molten alkali metal and elemental fluorine.
High-Temperature Silicone Rubber Sheets, Bars, and Strips
Also known as polysiloxane, this silicone rubber offers good resistance to ozone and salt water. Softer durometer rubber has better conformability; harder durometer rubber is more wear resistant.

Gold Foil
- Hardness: Rockwell B57 (Soft)
Since it’s thin and easy to cut, as well as highly conductive and corrosion resistant, this 99.99% pure gold foil is often used to plate electrical connectors that are exposed to the air. It’s also good for making parts that stay accurate in extreme environments because it has a high melting point, low thermal resistance, and won’t oxidize. An alternative to platinum, gold is more conductive, but has a lower melting point. Use it to make gaskets, even for high-vacuum applications, since it is soft enough to create a good seal when pressed between two flanges, but won’t damage the flanges so you can reuse them.
