In-Line Oil Temp Tee 16AN

The In-Line Oil Temp Tee 16AN is an essential monitoring component for serious automotive builders and engine tuners who demand real-time oil temperature data. This sandwich adapter threads directly into your engine's oil supply or return line, allowing you to install a quality oil temperature sender without drilling into the block or modifying factory galleries. Whether you're running a naturally aspirated build, forced induction setup, or street performance engine, accurate oil temperature monitoring is critical to preventing bearing wear, detonation, and catastrophic failure during sustained load or high-rpm operation.

Engineered with a 16AN port configuration, this tee fitting accommodates standard -16 hose or hardline tubing common in custom and motorsport fuel and cooling systems. The inline design maintains full flow through the circuit while providing a dedicated tap for a sender probe, ensuring minimal pressure drop and reliable signal transmission to your digital gauge or engine control unit. Cast from durable aluminum or ductile iron construction, the tee is rated for high-pressure and high-temperature environments typical of modern engine bays, resisting corrosion and thermal cycling without degradation.

This fitting is ideal for custom-built engines, turbo and supercharged platforms, and any application where factory oil temperature instrumentation is absent or insufficient. Installation requires minimal modifications—simply splice the tee into your existing oil circuit using compatible -16 hose, fittings, and clamps, then thread in your temperature sender. Compatible with aftermarket gauges and engine management systems from all major manufacturers, the In-Line Oil Temp Tee 16AN delivers the precision monitoring that separates a well-tuned, reliable build from one headed for the scrapyard.
