Ultra High Efficiency Fuel Filter Cat Ultra High Efficiency Fuel Filters are built to meet strict fuel cleanliness requirements demanded by tighter component tolerances, increased engine temperatures, higher injector pressures and strict emission guidelines. Caterpillar testing proves Cat Ultra High Efficiency Fuel Filters provide superior protection. Cat UHE Filters are quite simply the best filter you can buy for your Cat equipment. Maximizing injector life demands filtration capable of limiting the size and number of particles that get through the fuel filter. From a duration perspective, injectors tested with Cat elements significantly outlasted those tested with competitive filters. In addition, injectors exhibited significantly less wear and fuel leakage. See the test results. Constructed with a strong, one-piece can design and a non-metallic center tube that is cleaner and stronger than metal, Cat Fuel Filters maximize cleanliness and minimize potential leaks. When you want maximum productivity, choose filters from the equipment manufacturer itself – Cat Filters are always the best option for Cat machines. Our highly differentiated filters allow system components to function as designed and helps to avoid premature efficiency losses and failures by using: Proprietary filter media provides unsurpassed protection Acrylic beads to avoid bunching Spiral roving for better pleat stability A nylon center tube to prohibit metal contamination Molded end caps to stop leaks SPECIFICATIONS Efficiency Rating: Ultra High Efficiency COMPATIBLE MODELS Excavator 329E 319D LN 320E LRR 320E RR 320E 316E L 324E L 312D 318E L 314E LCR 319D L 312E 329E L 320D L 320D 323E LN 324E LN 312E L 314E CR 315D L 323D L 320D GC 323E L 320E L 320E LN 312D L 324E 323E SA
