Silicon-, PTFE and glass fibre reinforced gaskets (for EC-Cell pre-cut or NC material (non cut))

Description:

The components of the fuel cell do not in and of themselves make a good seal, so medical grade silicone gaskets (having precise thicknesses for reproducible sealing) are used to create airtight seals between components. These are the standard gaskets that are precision cut to fit ElectroChem fuel cells.
