Engineered for uptime.

Everywhere.
Every time.

High-performance diesel filtration systems built to withstand off-highway’s harshest conditions. Setting the standard since 1976.

Seeing IS Believing

DAVCO was formed in 1976 to improve the performance of diesel engines, and we haven’t stopped obsessing over performance ever since.

We are best known for bringing the industry’s first clear top design to market, saving you time and money by letting you know when – and when not – to replace your filters. Born from the product design, we call this idea SEEING IS BELIEVING® and it became a philosophy that is now embraced by employees across the company. We have led the category for nearly five decades, learning at every step of the journey, and we learned long ago that actions speak louder than words. Customers want proof.

While our name might be new to you, rest assured, we are not new to the off-highway space. We’ve built nearly 300,000 fuel water separators for off-highway customers since 2004. Fuel water separators are our specialty, which is why we want you to know our name.

So, no matter where your equipment runs – rivers, oil fields, farms, factories, or jobsites – just remember you can trust DAVCO to remain focused on you.
