Description
Cat® Advanced Efficiency Fuel Water Separators are designed to eliminate virtually all free water and 90% emulsified water along with smaller contaminates while helping extend the life of your fuel filter and sophisticated fuel injectors. See test results.
Injector erosion causes loss of power and increased fuel burn, which is why it's critical to protect your injectors by choosing longer-lasting Cat Fuel Water Separators. Manufactured in our own facilities, we control the quality of the parts you need to keep your equipment performing at optimum levels.
This results in more uptime and lower repair costs for your business.
Attributes: • Unique filter media provides unsurpassed protection. • Acrylic beads prevent bunching • Spiral roving provides greater pleat stability and maximum dirt holding capability • Nylon center tube prevents metal contamination • Molded end caps prevent leaks
Warning:This product can expose you to chemicals including Lead and lead compounds, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
