2-5/8in Mech Oil Pressure 0-200 Psi

The 2-5/8in Mech Oil Pressure 0-200 Psi mechanical gauge from AutoMeter is an essential analog instrument for any serious engine builder, tuner, or performance mechanic who needs real-time oil pressure monitoring. Unlike digital displays that depend on power and sensors, this mechanical oil pressure gauge operates independently using direct hydraulic line connection, making it reliable in high-vibration environments and during extended engine testing. Whether you're running a naturally aspirated street engine, forced-induction build, or track car, accurate oil pressure feedback is non-negotiable for engine longevity and performance diagnostics.

This gauge features a full-sweep mechanical movement rated from 0–200 psi, delivering smooth needle response across the entire pressure range with no electronic latency. The 2-5/8 inch diameter silver face is sized for standard mechanical gauge clusters and aftermarket dash installations, providing excellent visibility from the driver's seat. Direct oil gallery connection eliminates electrical noise and sensor drift—critical when diagnosing oil starvation issues, bearing wear, or verifying pump performance on freshly rebuilt engines. The ultra-lite construction minimizes dashboard weight, important for weight-conscious builds, while the analog display gives you immediate visual feedback without any software interpretation or calibration drift over time.

Mechanics and engine builders rely on this AutoMeter mechanical oil pressure gauge for street rods, restorations, performance builds, and engine dyno testing where absolute accuracy and independence from vehicle electronics matter most. Installation requires direct connection to an engine oil gallery port or block-mounted adapter—no wiring or power draw needed. The 0–200 psi range covers everything from mild street engines to high-output forced-induction applications, making it versatile across platforms. Its rugged mechanical construction withstands vibration, temperature extremes, and the repeated thermal cycling of modified engines, ensuring dependable readings for years of service.
