Sensor Temperature 1/8 NPT

The Sensor Temperature 1/8 NPT is a precision temperature sending unit engineered for automotive cooling system monitoring and engine diagnostics. Built for technicians, fleet operators, and engine builders who demand reliable coolant temperature feedback, this compact sensor delivers accurate readings to engine control units and aftermarket gauges. The 1/8 inch NPT male thread design ensures secure installation in standard engine block bungs and manifold ports across a wide range of vehicles and small engines.

This EQUUS temperature sending unit operates by converting coolant temperature into an electrical signal proportional to engine heat conditions. The 1/8 NPT threaded connection provides a leak-free, industry-standard interface that resists vibration and thermal cycling common in high-performance and heavy-duty applications. The sensor's compact form factor—measuring 4.1 x 0.6 x 4.1 inches and weighing only 0.05 lbs—allows installation in tight engine compartments without interference to adjacent components or hose routing.

Ideal for custom cooling system builds, engine swaps, and diagnostic gauge installations, the Sensor Temperature 1/8 NPT integrates seamlessly with factory and aftermarket dashboard instrumentation. Installation requires only a wrench and basic mechanical skill—simply thread the unit into a compatible engine port and connect the sender wire to your gauge or ECU harness. This sensor is essential for tuners monitoring water temperature on turbocharged engines, enthusiasts upgrading to digital gauge clusters, and service technicians replacing failed original equipment sensors.
