Gagelite Kit O/T 1/2in. NPT 270 Deg

The Gagelite Kit O/T 1/2in. NPT 270 Deg is a comprehensive oil temperature warning light system designed for automotive enthusiasts and professional mechanics who demand real-time engine monitoring. This complete kit from LONGACRE combines a sender, warning light, and wiring harness in a single package, eliminating guesswork during assembly and reducing installation time. Oil temperature monitoring is critical for engine protection—excessive heat accelerates oil degradation, increases bearing wear, and can lead to catastrophic engine failure if left unchecked.

This oil temperature gauge system operates via a 1/2-inch NPT threaded sender that screws directly into your engine block or oil filter adapter, making installation straightforward on most vehicles. The sender detects oil temperature and triggers the blue warning light when readings exceed the 270-degree Fahrenheit threshold—a critical safety point where oil viscosity breaks down and engine damage becomes imminent. The kit includes a precision-calibrated sender unit, a bright blue indicator light for high-visibility dashboard mounting, and pre-assembled wiring that connects sender to light with no additional splicing required. The compact design fits standard gauge holes and aftermarket dash panels.

This system is ideal for high-performance drivers, race car builders, and vintage car restorers who run their engines hard and need early warning of thermal stress. The 270-degree threshold makes it especially useful for modified engines, track vehicles, or those equipped with high-output alternators that generate excess underhood heat. Installation works on any vehicle with accessible engine block bosses or filter adapters featuring 1/2-inch NPT threads. The lightweight 0.34 lb kit mounts easily behind dash panels or in custom gauge clusters, making it a reliable choice for both street and competition applications.
