Description

The COILHOSE PNEUMATICS A400 is a pencil-style ball tire pressure gauge with a closed check design, built for accurate pressure readings in the 5 to 50 psi range. Constructed from aluminum with a chrome-plated finish, it is a compact, durable tool suited for tire service work across automotive, fleet, and equipment maintenance applications. The angled head allows easy valve stem access in tight spaces. At 0.25 pounds, it is lightweight enough to carry in a shirt pocket or tool bag without adding bulk to a technician’s kit.

This gauge is intended for use on tires found in light automotive, trailer, and small equipment service settings where working pressure falls within the 5 to 50 psi range. The closed check design holds the reading on the stem after the gauge is removed from the valve, allowing the technician to read the pressure at eye level without rushing. It suits tire shop technicians, fleet service personnel, and general trade professionals who need a reliable handheld gauge for routine pressure checks.

Installation Notes
