This new approach to in-line milk filtration consists of a stainless steel coil, a rubber retainer and a filter sock. Sock and coil are sized perfectly to provide a snug fit, eliminating the problem of excess filter media which can lead to voids, breakage and lack of uniform filtration. Long-lasting retainer features a slight lip on inside diameter to ensure proper and secure placement against stainless steel coil. 24"L, fits tri-clamp style ferrule for 1.5" tubing. Replacement retainer and socks sold separately. Patented.
