The Liquid Filled Series is extremely popular with our customers. We can’t blame them, we’re big fans too. How could you not be with the classic analog look, chrome body and silicone oil in the gauge.

Check out the Liquid Vacuum Gauges we just added with the option of a Black Dial or White Dial. There’s a 1/8-27 NPT Male Thread on the back so you can hook up a vacuum line and fittings to track compression and vacuum levels from -30 to 0 inHG.

With this Liquid Filled Vacuum Gauge you’ll stay alerted to possible air leaks or potential mechanical issues like faulty valves and cylinders. Problems like these can cause rough idling, poor fuel economy and increased emissions.

Not to mention this 1-1/2” (38mm) mechanical vacuum gauge looks really good. Along with the black gauge dial and white needle, or white gauge dial and black needle, this gauge is equipped with a clear lens as you take analog readings. The chrome body is waterproof, so this vac gauge is built to be durable.

The reason it’s filled with silicone oil is to protect the needle from engine vibrations. That way you know you’re getting accurate compression and vacuum readouts without any interference.

One of the reasons these gauges are so popular is because they’re simple, easy to use and easy to install without the need for power wiring or mounting hardware. You get a clean look and gain direct access to extremely reliable readouts at the same time.

Add our Mechanical Liquid Filled Vacuum Gauge to your application and monitor vibration-free readings at idle or check levels at cranking speed to assess if your car or truck’s engine is performing at peak efficiency.
