At Cobcraft, we are proud to present our commissioned SIS Silicon Carbide Cuplocks, designed for superior performance in high-temperature applications. These cuplocks are stronger and more heat-resistant than traditional Mullite, ensuring they remain intact under strain. Engineered to fit seamlessly with a stainless steel threaded rod, they allow complete adjustment for maintaining a perfect seal with ceramic fiber.
