12an Inline Filter Screen 250-micron

The 12 AN Inline Filter Screen 250-micron from SETRAB Oil Coolers is a precision fluid filtration component engineered for high-performance cooling and lubrication systems. Designed for motorsports, racing, and heavy-duty engine applications, this inline filter element protects critical engine components by removing contaminants before they reach sensitive hydraulic or oil passages. The 12 AN fittings ensure secure, leak-free connections to standard aftermarket cooling lines and adapters used in turbocharged, supercharged, and naturally aspirated engine builds.

This filter screen features a stainless steel construction that provides superior corrosion resistance and durability in demanding operating conditions. The 250-micron filtration rating effectively captures particulates while maintaining adequate flow rates, balancing protection with minimal pressure drop across the system. The compact design—measuring 4.1 inches in length with a slim profile of 2.3 x 1.2 inches—allows installation in tight engine bay spaces without sacrificing performance. Inline filtration at this specification is critical for protecting expensive oil coolers, thermostatic bypass valves, and precision bearings from ferrous and non-ferrous debris.

This filter element is ideal for track enthusiasts, professional race teams, and builders of custom engine cooling systems who demand reliability and cleanliness. It integrates seamlessly with SETRAB cooler systems and compatible aftermarket cooling setups using -12 AN hose adapters. Installation is straightforward—simply thread the adapter fittings into your existing line configuration between the engine block and cooler inlet. Regular inspection and replacement maintain optimal cooling efficiency and extend the service life of your entire cooling circuit.
