CoorsTek, Inc has come a very long way since they first manufactured oven-safe cookware in 1910, as the Herold China and Pottery Company. Not that we don't appreciate a fine pot roast, but they are now the largest technical ceramics manufacturer in the world, producing everything from mechanical seals to ceramic armor for the military. We have a selection of their Tetrafluor advanced seals and rings, made from long-lasting, high-quality polymer materials. Their Tetrafluor seals include pistol seals, rod seals, scraper seals and piston rings. You'll find the rings and seals we offer listed with their manufacturer part numbers for easy identification. If you have any questions about the correct part for your particular requirements, give our ace customer service representatives a call and they'll be happy to help. You might not be able to cook dinner in one of these high-performance seals, but it will give you top performance as part of your aircraft engine. |
