The DERALE In Line Fluid Thermostat with 10 AN inlet and outlet connections is a precision engine cooling control device designed to maintain optimal fluid temperature during high-demand operation. This 180-degree thermostat engages at 180 degrees Fahrenheit and disengages at 165 degrees, providing tight temperature regulation for systems requiring active thermal management—including performance cooling circuits, transmission coolers, and auxiliary fluid loops in race, marine, and heavy-duty applications.
The 10 AN inlet and outlet configuration delivers compatibility with standard high-flow cooling lines and fittings found in modern performance cooling systems. The 180-degree activation point is engineered for systems running warmer fluid temperatures where early cooling engagement would reduce efficiency—a common specification in transmission coolers, oil cooling circuits, and aftermarket cooling solutions. The differential between engagement (180°F) and disengagement (165°F) prevents thermal cycling and hunting, ensuring stable coolant flow without constant valve oscillation that causes pressure spikes and unnecessary strain on pump and line components.
This thermostat is ideal for builders and technicians installing custom cooling systems, upgrading transmission coolers, or retrofitting auxiliary fluid temperature control into performance platforms. The compact 2.75 × 1.35 × 4-inch footprint and lightweight 0.19 lbs design allow flexible installation in tight engine bays or auxiliary cooling locations where space constraints are critical. Direct AN port connections eliminate adapter requirements and potential leak points common with port-threaded alternatives.
DERALE is recognized for precision thermal management components across motorsports, marine, and heavy-duty sectors. This inline thermostat model delivers straightforward temperature-based flow control without complex electronic regulation, making it a reliable choice for systems where mechanical simplicity and proven performance are priorities.
