Racor Diesel Fuel Filters

Why Racor Is the Benchmark for Diesel Fuel Filtration

When it comes to protecting a diesel engine from the contaminants that cause the most damage, few names carry more weight than Racor. It all began in 1969 with a patented and exceptionally efficient new way to remove water, dirt, rust, and algae from diesel fuel. Since then, the brand — now the Racor Division of Parker Hannifin — has remained at the forefront of diesel filtration engineering. Parker Racor has earned the respect of engine and equipment builders, owners, and operators around the world, with genuine Racor filtration products setting the global filtration performance standard.

The Core Threat: Why Diesel Filtration Matters

Fuel contamination in the form of dirt and water can find its way into your fuel tank and cause significant damage. With modern engines injecting fuel at pressures over 30,000 psi and injector tolerances measured in microns, even a small amount of contamination can cause problems — water and particulates can cause microscopic injector surface damage and even clog the nozzle. Racor's diesel fuel filters are engineered specifically to intercept these threats before they ever reach precision engine components.

Racor's Signature Product Lines for Diesel

In the 1970s, Racor's innovative Turbine Series filters quickly captured market share by capturing water better than other diesel fuel filtration devices — exactly what the trucking industry needed at the time. Today, the Turbine Series remains a cornerstone of Racor's diesel lineup. The Turbine Series offers exceptional water-removing efficiency for both bulk and emulsified water, low restriction of fuel flow, and high dirt-holding capacity — with the patented Aquabloc® filter element at the heart of the system's three coalescing and filtration stages.

Racor's Diesel Spin-On Series filters and water separators are designed to protect engines by removing water, sand, dirt, and rust contamination from fuel. They are compact in size and cost-effective, made with a flexible mounting head for on-engine or remote mounting. For larger or more demanding applications, the Racor FBO assembly is specifically designed to meet the filtration requirements of today's high-pressure common rail diesel injection systems and is used for fuel dispensing pumps or as a primary fuel filter/water separator on large diesel engine applications.

Aquabloc® Technology and Build Quality

In the 1980s, Racor introduced its Aquabloc media to remove water from fuel, directly addressing the filtration demands of new electronically controlled engines with high-pressure injection systems. Their proprietary Aquabloc® media enhances contaminant capture while maintaining optimal flow rates, ensuring consistent engine performance even when fuel quality varies or environmental conditions are severe.

Racor's commitment to materials quality is equally rigorous. Racor employs top-notch materials and adheres to ISO/TS16949 production standards to eradicate bypass issues, ensuring only clean, quality fuel reaches the engine. High-quality automotive-grade gaskets and seals — including NBR, HNBR, and Viton® — ensure compatibility with B20 biodiesel and longevity throughout the service period. Racor's unique aluminum bowl construction offers resistance to low and high temperatures, impact resistance, and imperviousness to all fuel types, ensuring longevity and reliability in diverse operating conditions.

Choosing the Right Racor Diesel Fuel Filter

Consider filter micron ratings, flow rates, and mounting configurations when selecting the right Racor for your application. Racor elements are available in 2, 10, and 30 micron ratings. Use 2 micron media when the filter is the only or final filter in the system — Racor 2 micron media is designed to protect all modern injection systems. As a division of Parker, a global company with manufacturing facilities around the world, most Racor filters are designed, tested, and manufactured in the USA.
