Inline Temperature Tee -12a w/1/2in NPT Port

The Inline Temperature Tee -12a w/1/2in NPT Port from JOES RACING PRODUCTS is a precision adapter fitting engineered for serious engine builders, track enthusiasts, and performance mechanics who demand real-time coolant temperature monitoring. This compact yet robust tee fitting integrates seamlessly into high-performance cooling systems, allowing you to install a temperature sensor, gauge, or data-logging probe without disrupting your primary coolant lines. Whether you're tuning a race engine, diagnosing thermal issues on a modified vehicle, or building a custom cooling circuit, this adapter provides a dedicated port for accurate temperature feedback.

Constructed from aluminum and finished in bright red anodized coating for corrosion resistance and easy identification under the hood, the Inline Temperature Tee features 12 AN male ports on two branches and a 1/2 inch NPT female port for sensor installation. The red anodized finish not only protects against oxidation and coolant degradation but also makes this fitting visually distinct in complex plumbing layouts. The compact 3.25 x 3.1 x 5.05 inch footprint allows tight installation in engine bays where space is premium, while the 0.5 lb weight adds minimal burden to your overall system. This design ensures minimal flow restriction and thermal lag, critical factors when you need instantaneous temperature data for engine management and tuning decisions.

Custom car builders, drag racers, and performance shops rely on this inline tee to tap into cooling circuits for standalone ECU integration, auxiliary gauge clusters, or temperature-triggered fans and solenoids. The 12 AN male connections are standard in modern high-flow cooling systems, while the 1/2 inch NPT female port accepts virtually any aftermarket temperature sensor or transducer on the market. Installation requires minimal downtime—simply cut into your existing coolant line, install the tee with appropriate fittings, and thread in your sensor. This adapter is essential for anyone serious about engine diagnostics, tuning precision, and avoiding thermal failure on modified or race vehicles.
