Draper Expert Hi-Flo Air Line Inflator With Twin Open Ended Connector

The Draper Expert ALG43 Hi-Flo Air Line Inflator represents the next generation of professional airline inflators. This new and improved MK4 version builds on an already trusted design with a series of meaningful upgrades — making it the ideal choice for garage forecourts, tyre fitting bays, and any commercial environment where accuracy and throughput matter.

Industrial-quality fabrication sits at the core of the ALG43, delivering the robustness needed to withstand the rigours of daily professional use. The stronger yet lighter body makes it noticeably more comfortable to handle during extended sessions, while the 20% larger viewing window means pressure readings can be taken quickly and confidently without squinting at a small dial — a genuine time-saver in a busy workshop environment.

Twin open-ended connectors allow rapid attachment and detachment from tyre valves, keeping inflation jobs moving at pace. Improved internal engineering delivers increased accuracy over previous versions, and every ALG43 is supplied complete with a calibration certificate — giving workshop managers and fleet operators the documentation they need to demonstrate compliance and maintain service records.

With a pressure range of 0–9.6 bar (0–138 psi), a maximum air supply of 13.8 bar (200 psi), and a 0.5m hose on a standard 1/4" BSP taper female inlet, the ALG43 integrates seamlessly into any existing compressor setup.
