The In-Line Gauge is designed to provide accurate pressure readings during firefighting operations, making it an essential tool for standpipe systems, high-rise attacks, hose testing, and water flow monitoring. Installed directly into the hose line, it allows crews to quickly verify operating pressures and ensure proper water delivery to attack lines.
Constructed from hard-coat anodized 6061-T aluminum, the in-line gauge is lightweight, durable, and corrosion resistant. The protected gauge assembly features a luminescent, glycerin-filled 0–300 PSI gauge that is easy to read in low-light conditions while resisting vibration and shock. Available in both 1.5" and 2.5" NH configurations, this gauge is built for reliable performance in demanding fireground environments.
