STOPFIBER 300

A compound containing 100% pure expanded graphite fibres, which has been designed for use in critical temperature and pressure situations. Ideal for valves and pumps for heat transfer oil. Correctly installed, it can reduce leaks to zero, achieving results that are at times comparable to those of a mechanical seal. It does not score shafts and bushings and can be also used on old equipment in poor mechanical condition. Density: 710 cm3/kg

Applications

Stopfiber is a line of products with an extremely advanced sealing system designed for pumps, valves and rotating shafts in general, which, when inserted in a housing, surround the rotating shaft like a single sleeve which is extremely well lubricated and thereby completely eliminate any point of excessive pressure. Correctly used, Stopfiber products guarantee long life to the entire equipment, even previously damaged equipment. Their regular replacement guarantees a secure, efficient seal with minimum leaks. Containing no asbestos, they do not cause wear and resist high temperatures, aggressive chemical products and high peripheral speeds.
