Fluid Control Thermostat 1/2in NPT

The DERALE Fluid Control Thermostat 1/2in NPT is designed for serious engine builders and cooling system enthusiasts who require precise temperature management in high-performance applications. This thermostat addresses the limitations of stock cooling systems, which often fail to provide the necessary thermal regulation for heavily modified engines or vehicles operating under extreme conditions.

With its 1/2in NPT threaded connections, this thermostat integrates seamlessly into both OEM and aftermarket cooling systems, allowing for effective coolant flow management. The fluid control design enables precise regulation of coolant bypass and primary flow rates, preventing overcooling during cold starts and effectively managing heat rejection during high engine loads.

Ideal for builders of forced induction and high-output custom radiator systems, this thermostat's compact size makes it suitable for tight engine bays and creative plumbing layouts. Its compatibility with common industrial-grade fittings ensures flexibility in hose routing and system architecture, making it a valuable component for any custom cooling circuit.
