Silica Rope
The flat edges on these square-profile seals provide more sealing surface than round-profile seals. They're made of 98% silica for excellent temperature resistance. They're flexible and will conform to uneven surfaces. Push them into the groove that's commonly built into oven doors, furnaces, and tanks. They resist water, salts, and diluted acids.
