Meet the Tru-Flate Polycarbonate Air Line Gauge — a compact, reliable tool designed to deliver fast, accurate pressure readings in your pneumatic lines. Built with a durable polycarbonate body, it’s lightweight yet tough enough to withstand the demands of busy workshops, garages, and maintenance bays. Read pressure at a glance without wading through bulky gauges or bulky hardware.
-
Polycarbonate construction combines durability with clear visibility and a lighter footprint than metal gauges, making it a practical everyday companion in the shop.
-
Maximum pressure 300 psi covers the typical range for most shop air systems, regulators, and pneumatic tools, giving you a trustworthy reading without overkill.
-
1/4 in. NPT thread (male) ensures fast, secure connection to standard air ports and fittings found in most pneumatic setups.
-
1/4 in. air inlet aligns with common air lines for straightforward installation and testing workflows.
-
Lightweight and single-use packaging — weighing roughly 0.06 lb and shipped as a single unit for immediate use.
-
Brand: Tru-Flate, a name you can trust for practical, purpose-built air tooling.
Why this gauge matters in your workday
- Quickly verify that your compressor regulator, hoses, and tool inlets are delivering the expected pressure, reducing guesswork and improving tool performance.
- Spot-check line pressure during setup, maintenance, or troubleshooting to prevent under- or over-pressurization that could affect tooling or components.
- Use with standard 1/4" NPT ports to diagnose leaks or flow restrictions by comparing actual line pressure to expected values.

How to use
- Ensure the pneumatic system is depressurized before attaching the gauge.
- Thread the gauge into a matching 1/4" NPT port (male to female). Tighten by hand, then snug with a wrench—avoid overtightening.
- Power the system and read the pressure on the gauge face. Compare against expected values for your tool or regulator.
- When finished, relieve pressure, disconnect, and store in a dry, protected area.
Tips for best results
- Keep the gauge clean and free of oil, solvents, and heavy grime to preserve readability and response accuracy.
- Use with standard 1/4" NPT ports to maintain compatibility across a wide range of pneumatic equipment.
- If readings seem off, verify the port threads and seals are clean and undamaged before re-testing.
