Perfect-Fit® is a patented new approach to in-line milk filtration. The Perfect-Fit® System consists of a stainless steel coil, a rubber retainer and a Perfect-Fit® filter fitting securely around the coil. The sock and the coil are sized perfectly to make a snug fit, thus eliminating the problem of excess filter media which can lead to voids, breakage and lack of uniform filtration. The long-lasting rubber retainer features a slight lip on the inside diameter to insure proper and secure placement against the stainless steel coil.
