Virgin PTFE compounded with carbon fibre
Turcon® T40 is a carbon-filled PTFE material commonly used in applications where a low-lubricating hydraulic fluid is used. This material is often used in high-freqency and short stroke applications. Because of the surface texture of this material, it is best used for sealing liquids as opposed to gasses.
A 70 durometer FKM. FKM is an elastomer material known especially for its non-flammability, low gas permeability and excellent resistance to ozone, weathering, and ageing. The operating temperatures of the fluorocarbon rubber range between -20 °C and +200 °C (for a short period of time up to +230 °C). FKM is also often used with mineral based oils and greases at high temperatures. Used as an energizer in T46V and M12V
