Two And A Half Inch Vacuum Pressure Gauge Glycerin Filled Heavy Duty Build Minus Thirty To Zero InHg Range Quarter Inch NPT Lower Mount Stainless Steel Case Built For HVAC Lines Tanks Piping And Air Pumps

2.5in Vacuum Pressure Gauge, Glycerin-Filled, Lower Mount
✔️ 1/4 in NPT lower mount, glycerin-filled, brass/stainless

This heavy-duty vacuum pressure gauge is built for HVAC lines, tanks, piping, and air pumps. Its glycerin-filled internals smooth readings, while the 304 stainless steel case resists corrosion in moist environments. With a -30 to 0 inHg dual scale, accurate to ASME B40.100 Grade B, and IP67 waterproof protection, it’s ready for harsh field use and reliable readings in liquids and non-corrosive gases.

✅ 2.5-inch dial with dual scale: -30 to 0 inHg / -1 to 0 bar
✅ Glycerin-filled internals reduce pointer flutter and protect mechanism
✅ 304 stainless steel case resists corrosion
✅ Brass and stainless steel construction for non-corrosive liquids and gases
✅ 1/4 in NPT lower-mount connection for easy installation
✅ IP67 waterproof rating keeps readings clear in damp environments
✅ ASME B40.100 Grade B accuracy ±3/2/3% of span
