Coilhose Pneumatics A539 Dial Tire Pressure Gauge

Product Description

The COILHOSE PNEUMATICS A539 is a dial-style tire pressure gauge designed for dual tire applications on commercial vehicles, trailers, and fleet equipment. It features a straight-style chuck and reads pressure from 0 to 160 psi, covering the full range needed for most truck, bus, and heavy-duty trailer tires. The closed-check design holds the reading after the chuck is removed, allowing the technician to read the dial without holding the gauge on the valve stem. This gauge is built for shop and field use by tire technicians, fleet maintenance crews, and commercial vehicle service professionals.

The A539 is suited for dual tire configurations where access to inner rear tires requires a straight chuck rather than an angled style. The 12-inch hose length provides enough reach to comfortably access inner dual valve stems. Typical applications include fleet service bays, truck stops, and mobile tire service operations where accurate inflation monitoring is critical to load rating compliance and tire longevity.

Key Features

• 0 to 160 psi range covers standard truck, trailer, and heavy-duty tire inflation requirements
• Straight dual-tire chuck style for inner rear tire access on dual-wheel configurations
• Closed-check mechanism holds pressure reading after chuck is removed from valve stem
• Dial display provides clear, direct pressure readings without battery dependency
• 12-inch hose length for improved reach to recessed or inner valve stems

Compatibility

Designed as a replacement or service gauge for dual tire assemblies on commercial trucks, trailers, and heavy-duty vehicles requiring a straight-style chuck and a 0 to 160 psi measurement range.

Installation Notes

No permanent installation is required. This is a handheld service tool used by tire and fleet maintenance technicians. Ensure the valve stem is clean and free of debris before attaching the chuck to avoid inaccurate readings or air loss. Follow vehicle manufacturer and DOT guidelines for proper inflation pressures specific to the tire and load rating in service.
