422-7587 Secondary Fuel Filter
Ultra High Efficiency Fuel Filter
Description
Cat® Ultra High Efficiency fuel filters are designed to meet the stringent fuel cleanliness requirements of applications with tighter component tolerances, higher engine temperatures and injection pressures, and strict emissions guidelines. Caterpillar testing proves that Cat Ultra High Efficiency fuel filters provide superior protection. Cat UHE filters are the best filters you can buy for your Cat equipment.
To maximize injector life, filtration must limit the size and number of particles that pass through the fuel filter. In terms of durability, injectors using Cat filter elements outlasted injectors tested with competitor filters. In addition, injector wear and fuel leakage were significantly reduced. See test results.
Cat fuel filters feature a robust one-piece canister design and a non-metallic center tube that is cleaner and stronger than metal, maximizing cleanliness and reducing potential leaks.
If you want to maximize productivity, choose filters from the equipment manufacturer – Cat filters are always the best choice for Cat machines.
Our highly differentiated filters enable system components to perform as designed and help prevent premature efficiency loss and failure by:
- Proprietary filter media provides superior protection
- Acrylic beads prevent bunching
- Spiral roving improves pleat stability
- Nylon center tube prevents metal contamination
- Molded end caps prevent leakage
