R7188C Truck Pencil Pressure Gauge

Built for the higher-pressure demands of commercial vehicles, the R7188C pencil gauge covers a 10 to 150 psi range that matches the tire pressures used on trucks and buses, well beyond what a typical passenger car gauge measures.

The pen-style body extends to reveal a graduated scale that lets a technician read pressure at a glance, and its slim profile slides easily into a shirt pocket or tool pouch for quick access during roadside checks or yard inspections.

Its all-metal chrome construction stands up to the rougher handling common in fleet and commercial settings, giving drivers and maintenance crews a durable, pocket-ready gauge for routine pressure verification on heavy vehicles.
