Vacuum Gauge Liquid Filled

Vacuum Gauge – Liquid Filled (1/4" NPT)

This liquid-filled vacuum gauge provides smooth, stable readings for composite shop vacuum systems. The fill dampens vibration and needle flutter for more accurate, easier-to-read measurements during bagging and infusion. The dial displays both inHg (inches of mercury) and bar so you can monitor vacuum level at a glance on catch pots, manifolds, and pump lines.

Key Features

• Liquid filled to damp needle vibration and improve readability/accuracy
• Dual scale: reads in inHg and bar
• Connection: 1/4" NPT (bottom mount)
• Ideal for vacuum bagging & resin infusion (VARTM) setups
• Great for catch pots, accumulators, manifolds, and pump monitoring

Typical Uses

• Verify vacuum levels during leak checks and draw-down
• Monitor vacuum stability throughout cure/infusion
• Permanent or portable gauge on shop vacuum circuits
