Abstract: A cap for a filter includes an interior filter-contacting surface which frictionally engages an outer surface of the filter. Opposed to the interior surface is an exterior gripping surface having an average surface roughness ranging between about 0.025 mm and about 4.6 mm (peak to valley).
