Water Temp Sender 3/8in. NPT 230 Deg

The Water Temp Sender 3/8in. NPT 230 Deg is a precision electric temperature sensor engineered for engine monitoring systems in performance vehicles, marine applications, and industrial equipment. This Longacre component communicates coolant temperature data to gauges and engine management systems, providing real-time feedback essential for engine protection and tuning. Vehicle builders and engine technicians rely on accurate temperature senders to prevent overheating, optimize fuel mapping, and maintain reliable operation under demanding conditions.

The sender features a 3/8-inch NPT (National Pipe Taper) male thread, the industry-standard connection for engine block water jacket ports. Its 230-degree Fahrenheit maximum rating ensures compatibility with high-performance cooling systems and allows early warning of thermal stress. The electrical design delivers consistent signal output across the full temperature range, minimizing gauge fluctuation and providing stable readings on analog or digital display systems. Longacre's engineering ensures repeatability and durability in environments subject to vibration, thermal cycling, and coolant chemical exposure.

This temperature sender integrates seamlessly into street rods, race cars, custom trucks, and marine powerplants where factory gauge clusters have been replaced or upgraded. Installation requires direct threading into a 3/8-inch NPT port on the engine block or intake manifold; no adapters or bungs needed for standard applications. Builders choosing Longacre instrumentation benefit from plug-and-play compatibility with most analog temperature gauges and modern digital dash systems. Lightweight at just 0.12 lbs, the compact form factor (4.2 x 1 x 5.55 inches) fits tight engine bays without interference with hoses or wiring harnesses.
