Stack Gauge, Boost Press, Mech, 52Mm, White, -30Inhg To +30Psi, Incl T-Fitting

Features:

• Bronze bourdon tube 270° sweep movement

• Mechanical gauges do not require 12V power to operate. They make direct physical contact with the item they are reading. They do this through tubing or lines, which eliminates the need for electric signals.

• Ideal for vehicles that operate on voltages other than 12V, with no voltage at all (magneto applications) or operate on a battery with no generator.
