In-Line Oil Temp Tee 12AN

The ALLSTAR PERFORMANCE In-Line Oil Temp Tee 12AN is a precision temperature monitoring solution designed for serious engine builders, race mechanics, and performance enthusiasts who demand real-time oil temperature data under load. This adapter bridges the gap between your oil line and a quality temperature sensor, allowing you to monitor engine health during dyno testing, drag racing, road course sessions, or street driving.

Oil temperature is one of the most critical parameters for engine longevity—it directly affects viscosity, bearing protection, and overall performance—making this tee an essential component in any comprehensive tuning setup. Constructed as an inline tee fitting with a 12 AN (AN12) port configuration, this adapter uses a proven sandwich design that threads directly into your existing oil supply or return line without requiring major plumbing rework.

The tee allows simultaneous connection of your primary oil line and a remote temperature sensor bulb, eliminating the need for secondary drilling or complex manifold modifications. Precision machining and proper port alignment ensure minimal turbulence and accurate temperature readings across the full operating range. This fitting is ideal for engine swaps, supercharged and turbocharged applications, and any build where accurate oil temperature monitoring is essential.
