Abstract
A liquid precoat filter has a multitude of elongated replaceable filter elements that have one of their ends supported on tubes that project upwardly from a tube sheet. A multi-component, spring-biased, sliding seal prevents leakage between the filter elements and their support tubes. Externally engageable connectors are used to releasably fasten the filter elements to their tubes.
