Abstract
A filter has a series of porous, compressible filter elements sealed at their outer edge by a collar of silicone rubber that is flowed into the filter elements. The collar seals with an annular recess around the inside of a filter housing so that flow through the housing is confined to the filter elements without any compression of them.
