AUTO METER Mechanical Oil & Water Pressure Autogage — Black 2.3125 in Steel Console, 270° Sweep

The AUTO METER 2392 Autogage is a compact mechanical oil and water pressure gauge set in a steel console, designed to provide reliable, power-free readings for street and performance vehicles.

This 2.3125-inch Autogage from AUTO METER pairs rugged construction with straightforward operation for drivers who need dependable oil and water pressure indication without relying on vehicle electrical systems. Built with a bronze bourdon tube and durable nylon gearing, the gauge offers a 270° sweep for easy-to-read measurements and is supplied with fittings, tubing, and bulb assemblies so it’s ready for installation on a wide range of vehicles.

How does this gauge work without electrical power?

The 2392 Autogage is a mechanical instrument that uses a bronze bourdon tube to convert fluid pressure into dial movement, removing the need for an electrical sender or power source. Because it’s not electrical, it’s especially suitable for older vehicles, race applications, or low-voltage systems where reliability matters.

• Bronze bourdon tube mechanism for purely mechanical operation.
• 270° sweep for precise, visible pointer movement.
• No electrical connections required—reduces wiring complexity.
• Ideal for vehicles with limited or no electrical supply.

What hardware and accessories are included for installation?

Auto Meter supplies the 2392 with several plumbing adapters, tubing lengths and a bulb/socket assembly so you have the necessary parts to fit common threads and routing needs. The included parts let you install the gauge quickly without hunting for extra fittings.

• 1/4 inch, 3/8 inch, and 1/2 inch NPT adapter/fittings for thread compatibility.
• 6 ft of main tubing plus 1 ft nylon tubing with 1/8 inch NPT fittings.
• Bulb and socket assembly with red and green covers for nighttime visibility.
• Steel console sized for a 2.3125 in gauge for a clean dash fit.

How durable and precise is the Autogage for performance use?

The gauge combines time-tested materials and precision gearing to withstand demanding environments while delivering repeatable needle movement. Nylon gearing and a bronze bourdon tube have proven long life in street and performance settings for more than two decades.

• Durable nylon gearing resists wear under repeated use.
• Bronze bourdon tube rated for rugged service and accurate reading.
• 270° indicator sweep improves resolution and legibility at a glance.
• Steel console protects the instrument and presents a neat dash appearance.

What should I know about compatibility and fitment?

The 2.3125-inch diameter fits a standard regular gauge opening, and the assorted NPT adapters make it easy to mate with many engine and plumbing setups. Verify thread sizes on your engine ports or adapters before installation for a smooth fit.

• 2.3125 in gauge diameter fits common regular panel cutouts.
• Adapters included for 1/4", 3/8" and 1/2" NPT thread options.
• Supplied tubing supports typical routing distances for engine bays.
• Works well on classic cars, race machines, and performance builds with minimal electrical systems.

Who is this for? The AUTO METER 2392 Autogage is aimed at budget-conscious enthusiasts, restorers, and racers who want a reliable mechanical oil/water gauge that doesn’t depend on a vehicle’s electrical system. If you need a rugged, easy-to-read pressure indicator for older cars, low-voltage builds, or track vehicles—complete with fittings and illumination hardware—this compact steel-console gauge is a practical, proven choice.
