The Draper Air Line Gauge (DR16234) is a handheld pressure gauge designed to measure compressed air pressure in vehicle tyres and workshop pneumatic lines. Its primary use is quick, on-hose pressure checks and tyre inflation work where a durable, easy-to-read gauge is required to confirm pressure before service or testing.

Construction uses a chrome-plated brass inlet and body with a stainless-steel bourdon tube movement and a polycarbonate lens to resist impact. The gauge is supplied with a rubber protective sleeve to reduce damage in workshop use. Threading is 1/4" BSP male to fit standard UK air hose fittings and quick-release couplers (conforms to ISO 228-1 parallel pipe threads where applicable). The dial is available in a 0–15 bar (0–220 psi) range with a clear, colour-marked face; accuracy is typically ±2.5% of full scale in line with common workshop-grade pressure gauges and the instrument’s design follows the requirements of BS EN 837-1 for bourdon tube pressure gauges.

This air line gauge features an integral clip-on tyre chuck suitable for Schrader valve use, allowing hands-free pressure checks during inflation. No drive type applies; the head is a push/clip-on style intended for rapid attachment and reliable sealing under normal workshop pressures. Internals are corrosion-resistant stainless steel and brass to maintain performance where moisture and lubricants are present in compressed air systems.

Typical applications include garage tyre bays, mobile tyre technicians, vehicle workshops, agricultural machinery maintenance and general pneumatic tooling inspection. Industries that benefit from this tool include automotive repair, fleet maintenance, agriculture and light industrial workshops where routine tyre pressure verification and quick diagnostics are required.

Key benefits are straightforward compatibility with standard 1/4" BSP air fittings, corrosion-resistant brass and stainless components for long service life, impact protection from the rubber sleeve, and a practical pressure range and accuracy appropriate for workshop and roadside use.
