Show original supplier description
The AutoMeter 4531 Ultra-Nite is a 2-5/8" mechanical water temperature gauge engineered for drivers who need precise and rapid temperature readings. Its advanced bourdon tube meter movement ensures unparalleled performance, making it ideal for monitoring critical engine temperatures. The gauge operates within a 140-280°F range and comes equipped with a 6-foot capillary tube and a 1/2" NPT mounting nut for versatile installation. This gauge features a luminescent dial that glows green in low-light conditions, perfect for dimly lit tracks when external lighting is unavailable. It operates without an electrical system, making it compatible with virtually any street or race vehicle. The waterproof housing protects the internal components from moisture and debris, allowing it to be easily cleaned after racing. The kit includes the necessary 1/2" NPT adapter, mounting hardware, and detailed instructions to facilitate installation.
