Sealey SA500 Rechargeable Clip On Digital Tyre Inflator

The Sealey SA500 is a rechargeable clip-on digital tyre inflator designed for accurate, portable tyre pressure checking without the need for a mains power supply or separate air compressor. Built around a die-cast aluminium body with a rubber protector for grip and comfort, the SA500 is a robust yet handheld gauge-style tool suited to workshop bays, mobile mechanics, and roadside use. The advanced ceramic sensor delivers precise pressure measurement to an accuracy of 0.01 bar / 0.1 psi, making it a reliable choice for professionals where accurate readings matter. The large backlit LCD display is easy to read in low-light conditions and shows readings across four units — psi, bar, kPa, and kg/cm² — covering the full range of vehicle pressure requirements. The flexible 500mm hose and clip-on 1/4" BSP connector make connection straightforward across a wide variety of valves. Powered by a rechargeable lithium battery and charged via the included USB-C cable, the SA500 is designed for convenient top-up charging in the workshop or on the go. A low charge sound indication alerts the user before power runs out, and the auto power-off function activates after 90 seconds of inactivity to preserve battery life. A built-in magnet on the rear allows the unit to be stored conveniently on any steel surface.
