Sealey VS931 Air Brake Test Gauge for HGV

The Sealey VS931 is an air brake test gauge designed for diagnosing air brake pressure issues on HGVs and other commercial vehicles. This professional diagnostic tool enables mechanics and mobile technicians to quickly identify brake system faults, making it equally suitable for workshop use or roadside callouts. The unit features a large, easy-to-read gauge calibrated from 0-20 bar (0-300 psi), providing accurate pressure readings across the full operating range of commercial vehicle air brake systems. The gauge is protected by a rubber bumper for durability in demanding workshop environments, whilst the 2-metre hose provides sufficient reach to access test points on larger vehicles without difficulty. The kit comes complete with male and female couplings to suit different vehicle applications, plus a wire brush for cleaning test points before connection. The M16 x 1.5mm test point adaptor ensures compatibility with standard HGV brake systems. All components are supplied in a protective storage case for organised transport and secure storage between jobs.
