Cassette Seal / Case seal

High-speed PTFE lip seals are designed for rotary applications where elastomer lip seals fail, and mechanical seals are too costly. Single or multiple seal elements can be combined into a single canned seal pack. The filled PTFE sealing element provides chemical compatibility, a wide temperature range and high-pressure capability.
