Description

The STACK ST3108 is a 52mm mechanical water temperature gauge that offers a reliable solution for monitoring engine coolant temperatures, especially in vehicles with limited or no electrical systems. Its design is ideal for applications running on voltages other than 12V, magneto ignitions, or vehicles without a generator. The gauge features a black dial face with a white LED illuminated needle and a bronze bourdon tube for precise measurement, offering a 270° sweep for clear readability. Constructed for durability and accuracy, this mechanical gauge operates by making direct physical contact with the component it monitors via tubing or lines, bypassing the need for complex electrical wiring. This makes it particularly suitable for classic cars, race vehicles, or any application where electrical interference or power limitations are a concern. While the gauge itself does not require 12V power for basic operation, a 12-volt supply is necessary if backlighting is desired. The ST3108 utilizes a 1/2" NPT male fitting for connection, ensuring a secure installation. The gauge is designed for a temperature range of 120-240 degrees Fahrenheit. It is noted as a universal, non-application-specific part, meaning it can be adapted to a wide variety of vehicles and custom builds. The product is also compatible with braided stainless steel lines for a robust setup.
