The reliability and efficiency of any filtration system is chiefly dependent on the quality of the cartridges used in it. We’ve worked hard to develop a full line of quality HILCO® cartridges for virtually every application. HILCO can restore many oils and coolants to a like-new condition. Our full line of filter cartridges includes various sizes, filtration efficiencies and dirt-holding capacities. All of our filter cartridges are developed to provide long service life and high quality. HILCO cartridges feature quality design and construction. We also make HILCO-quality replacements for other brands of cartridges used in lube oil and fuel oil applications.
