In-Line Oil Temp Tee 12AN

The ALLSTAR PERFORMANCE In-Line Oil Temp Tee 12AN is a precision temperature monitoring manifold engineered for high-performance engine cooling systems. This aluminum temperature sensor adapter mounts directly into the oil line and provides real-time coolant temperature data to aftermarket gauge clusters, making it essential for serious engine builders, fabricators, and performance enthusiasts who require accurate thermal monitoring during development and track operation.

Constructed from black anodized aluminum, the manifold features dual 12 AN male fittings (inlet and outlet) that integrate seamlessly into -12 AN hose systems, a standard in modern fuel and coolant circulation. The 1/2-inch NPT female port accepts aftermarket temperature sender units, while 1/4-inch mounting holes enable secure fastening to engine bays or custom brackets. The tee configuration allows uninterrupted oil flow while bleeding off a sensor line, eliminating the need for restrictive bypass adapters. ALLSTAR PERFORMANCE's manufacturing tolerances ensure leak-free operation under sustained pressure.

This component is ideal for engine swaps, custom hot rod builds, racing fuel systems, and any application where factory temperature monitoring is absent or insufficient. Users installing modern EFI systems, custom cooling loops, or turbo-charged engines rely on manifolds like this to prevent guesswork during dyno tuning and road testing. The compact 4.9 x 1.85 x 6.95-inch footprint fits tight engine compartments without requiring extensive rerouting of cooling lines.

In the broader context of coolant system design, temperature sensing manifolds serve as critical safety devices—they allow drivers to catch thermal creep before catastrophic overheat conditions damage engine internals. ALLSTAR PERFORMANCE is recognized for manufacturing cost-effective performance cooling components that meet the demands of small-block restorations, LS swaps, and vintage drag racing programs.
