Air Pressure Gauge
Volvo

An air pressure gauge provides a critical window into the health of a Volvo truck’s compressed air system. This instrument measures system pressure with precision, enabling operators to monitor brake circuit readiness, air reservoir status, and agricultural or commercial vehicle applications that rely on reliable pneumatic control. A high-quality gauge features a durable stainless-steel case, a clear dial, and a responsive needle that tracks pressure changes quickly—vital for safety-critical decisions during pre-trip inspections. Accurate readings help prevent brake fade, reduce the risk of air leaks going unnoticed, and ensure the system maintains the correct cutoff pressures for optimal braking performance. The gauge should be calibrated to match the vehicle’s specified pressure range and tested for pinhole leaks, especially in environments with wide temperature fluctuations. In fleet maintenance, timely replacement when readings drift or the case shows signs of damage keeps downtime to a minimum.
