Derale Tube-Type Fluid Cooler 13.5 x 7.625 in, Black Powder Coat — 6 AN Fittings, Aluminum

The Derale 13.5 x 7.625-inch tube-type fluid cooler is a compact, six-pass aluminum cooler with embossed tube turbulators and 6 AN male fittings for efficient heat extraction in universal cooling installations.

This compact cooler is designed to lower operating temperatures for oil, transmission fluid, power steering fluid, or other compatible liquids in vehicles and industrial equipment. Built from aluminum with a durable black powder coat finish, the cooler combines a multi-pass tube layout with internal turbulators and copper tubing mechanically bonded to aluminum fins to maximize thermal transfer while fitting into tight spaces.

How does this cooler improve heat transfer in constrained installations?

The Derale tube-type design forces fluid through six sequential passes, increasing residence time and temperature differential across the core. Embossed turbulators inside each tube create internal agitation of the fluid, breaking up laminar flow and boosting convective heat transfer.

• Six-pass routing for longer fluid path and improved cooling efficiency
• Embossed turbulators in each tube to disturb fluid layers
• Copper tubing expanded into aluminum fins for solid thermal conduction
• Compact dimensions (13.5" x 7.625" x 0.75") for tight mounting locations

What are the connections and materials—will it fit my lines?

This cooler uses 6 AN male inlet and outlet fittings, a common sizing in performance and retrofit applications. The core assembly features copper tubing mechanically expanded into aluminum cooling fins, and the entire assembly is protected by a black powder coat to resist corrosion from road and workshop environments.

• 6 AN male inlet/outlet—compatible with standard AN hose and adapter fittings
• Aluminum core and end tanks for lightweight durability
• Copper tubing integrated with aluminum fins to enhance heat path
• Black powder coat finish for added corrosion and abrasion resistance

How is the cooler protected and how durable is it for everyday use?

The powder-coated aluminum body helps resist corrosion and surface wear while maintaining a lightweight profile. Extruded plastic fin guards protect the delicate aluminum fins from impact and debris without impeding airflow, extending the cooler’s service life in automotive and industrial settings.

• Black powder coat for environmental protection and a low-reflective appearance
• Plastic fin guards reduce damage from stones and tools
• Sturdy tube-to-fin mechanical bond resists vibration-induced loosening
• Universal form factor simplifies retrofit into many mounting configurations

What practical installation and maintenance considerations should I know?

The cooler’s slim profile and standardized fittings make it straightforward to position in front of radiators, behind bumpers, or inside engine bays with limited clearance. Maintenance is minimal—periodic inspection for bent fins, leaks at fittings, and ensuring fin guards remain intact are generally sufficient to keep it performing.

• Slim 0.75" thickness to fit narrow mounting pockets
• Use AN-compatible hoses or adapters to match existing plumbing
• Check fin guards and fittings during routine service intervals
• Flush and replace fluid per vehicle or equipment manufacturer recommendations

Who is this for: The Derale 13.5 x 7.625 tube-type fluid cooler suits owners and technicians seeking a compact, high-efficiency add-on cooler for automotive performance builds, towing rigs, or industrial systems where space is limited. It’s targeted at those needing reliable fluid temperature control with common AN plumbing, durable construction, and straightforward installation, without requiring a custom-fabricated solution.
