Abstract
A filter boot having a radially extending annular flange which is used to properly seat the filter boot to a tube sheet. The filter boot utilizes two annular recesses for properly affixing a pleated filter to the filter boot. A deep annular upper recess is provided at the end of the boot closest to the flange. An opposing lower annular recess faces opposite the first recess. Both the upper and lower annular recesses are separated by an annular base which has a plurality of holes located therein allowing potting compound to enter the entirety of the lower recess and a small portion of the upper recess. The perimeter of the area where the potting compound is held is stepped so that the boundary of the potting compound follows a tortuous path to better seal the boot and filter combination. The filter is potted within the lower recess while the potting compound remains fluid and dries around the filter securely affixing it within the lower recess of the boot.
