The Air Tyre Inflator Dial Gauge is a hand‑operated tyre inflation and pressure‑measurement tool designed to inflate tyres and read pressure accurately at the point of use. It combines a dial pressure gauge with an inflation hose and locking chuck so you can inflate a tyre, check the pressure and precisely bleed off air to reach the required setting without moving between tools. The primary use case is routine tyre maintenance and servicing in workshops, garages, fleet yards and racetrack pit lanes.

The unit features a chrome‑plated brass gauge body with brass internals and a reinforced nitrile (NBR) rubber hose for resistance to oils and workshop fluids. The dial is a bourdon tube type manufactured to EN 837‑1 standards, with a typical accuracy class of 2.5% full scale. Gauges are commonly supplied with a 63 mm diameter dial marked in psi and bar (for example 0–160 psi / 0–11 bar). The inflator connects to workshop air lines via a 1/4" BSP male fitting to suit standard quick‑couplers, and the end of the hose is fitted with a lever‑action clip‑on chuck for Schrader valves; adapters for Presta valves or needle inflation are commonly used if required. An integrated bleed/pressure‑release valve allows fine adjustment of pressure after inflation.

Typical applications include passenger and commercial vehicle tyre servicing, agricultural and plant machinery maintenance, motorsport pit servicing, fleet and rental vehicle checks, and general workshop use where rapid, repeatable tyre pressure checks are required. The device is suitable for tubeless and tube tyres fitted with Schrader valves and for ancillary inflation tasks with the appropriate adapters.

Key benefits include corrosion resistance from chrome plating and brass internals, accurate pressure readings compliant with EN 837‑1, convenient hands‑free inflation using the locking chuck and easy compatibility with standard 1/4" BSP compressed air systems. The reinforced hose and brass fittings deliver durability and service life in busy workshop environments.
