Fluid Control Thermostat Kit 3/8in NPT

The DERALE Fluid Control Thermostat Kit with 3/8in NPT is a remote oil thermostat assembly designed to regulate engine oil temperature in custom cooling systems. This polished aluminum unit features dual 3/8 in NPT inlet and outlet ports, allowing integration into both primary and auxiliary oil circuits for precise thermal management across a wide range of engine platforms and cooling configurations.

The kit includes four 3/8 in NPT male to 3/8 in hose barb fittings, enabling quick and reliable connections to standard oil hose assemblies without requiring additional adapters. The dual-port design accommodates both supply and return lines, making this thermostat suitable for applications ranging from street-performance engines to high-horsepower builds where oil cooling demands exceed factory specifications. The polished aluminum construction resists corrosion while maintaining a professional appearance in visible engine bay installations. Users can confidently integrate this unit into remote-mounted oil cooler setups, sandwich filter systems, or standalone cooling circuits where active temperature control prevents oil breakdown at extended operating temperatures.

This thermostat assembly is ideal for engine builders, automotive enthusiasts, and shops that require flexible, modular cooling solutions. Whether managing oil temps on turbocharged street cars, track-focused platforms, or off-road vehicles operating in extreme conditions, the 3/8in NPT Fluid Control Thermostat Kit delivers the performance-tuned temperature regulation necessary to extend oil life and protect internal engine components. Its compact footprint (4.5 x 2.3 x 7.35 in) and lightweight design (1.09 lbs) allow for discreet mounting in tight engine bays or under-hood spaces.
