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. The individual filter elements are releasably connected to the tubes by couplings that permit a spring clip to lock under shoulders when the filter element is pushed down; the spring clip is released when the filter element is rotated about one-quarter of a turn. A sliding seal prevents leakage between the filter elements and their support tubes.
