423-8521 Fuel Water Separator and Fuel Filter
High Efficiency Fuel Water Separator
Description
Cat® High Efficiency fuel water separators remove virtually all free water and 90% of emulsified water, as well as smaller contaminants, while helping extend the life of fuel filters and precision fuel injectors. See test results.
Injector corrosion causes power loss and increased fuel consumption, so choosing more durable Cat fuel water separators to protect your injectors is critical. We manufacture parts in our own facilities, controlling the quality of the parts you need to keep your equipment running at its best.
This means more uptime and lower repair costs for your business.
