Glycerin-Filled 2-1/2 Inch Dial Pressure Gauge Built Tough With Stainless Steel Case And Brass Inside, 1/4 Inch NPT Lower Mount, Great For Gas And Air Systems, Reads Vacuum And Pressure From -30 InHg To 30 Psi -100 kPa To 200 kPa

Glycerin-Filled 2.5-Inch Dial Gauge (Single Gauge)
✔️ Reads vacuum and pressure from -30 inHg to 30 psi, 1/4 NPT lower mount

This glycerin-filled dial gauge measures both pressure and vacuum in gas and air systems. Its robust 304 stainless steel case and brass internals resist corrosion, while a clear polycarbonate window protects the dial in tough environments. Ideal for HVAC testing, pneumatic tooling, and lab setups.

✅ 2.5 inch dial size (63.5 mm) for easy reading
✅ 304 stainless steel case with crimped ring for durability
✅ Brass internals and connection for gas compatibility
✅ Compound range: -30 inHg to 30 psi (-100 kPa to 200 kPa)
✅ Accuracy: ±3-2-3%
