Hilco Replacement Cartridges

HILCO makes quality, “Made In USA” replacement elements for our own equipment as well as for competitor housings. These elements are not only competitively priced, but are guaranteed to perform equal or better than the elements they are replacing. Some of the quality filters include replacements for Indufil®, Pall, Parker, Kaydon, GE, Siemens-Westinghouse, MHI, National Filters, Dollinger, and Alstom.

We know our elements work because they are tested for performance. We put the same quality manufacturing into all of our filter elements, no matter what equipment in to which they are installed.
