The AutoMeter Ultra-Nite mechanical oil temperature gauge, 66.7mm, 140–280°F range, uses an ultra-precise Bourdon tube movement and includes a 6" capillary tube plus 1/2" NPT mounting nut. Luminescent dials glow green for low-light visibility without power, and the kit ships with the NPT adapter, mounting hardware, and installation instructions to monitor oil temperature accurately in demanding conditions.
