Draper Expert Professional Air Line Inflator with Lock-On Connector

The Draper Expert ALG44 Professional Air Line Inflator is the lock-on connector variant of Draper's acclaimed MK4 Hi-Flo inflator range — purpose-built for garage forecourts, tyre fitting bays, and commercial workshops where precision, durability and speed are everyday requirements.

Like its twin-connector sibling the ALG43, the ALG44 MK4 brings a series of well-considered improvements over previous generations. The stronger yet lighter body reduces operator fatigue during extended use without sacrificing any of the industrial robustness demanded by professional environments. The 20% larger viewing window delivers a noticeably clearer, faster gauge reading — a small but significant advantage when working through a queue of vehicles on a busy forecourt.

Where the ALG44 sets itself apart is in its lock-on connector, which clamps firmly to the tyre valve and stays securely in place throughout the inflation or deflation process. This hands-free connection is particularly valued in tyre fitting bays and transport depot settings, where operatives need both hands free to manage the hose, read the gauge, and control airflow simultaneously. Increased accuracy over previous versions ensures every pressure reading can be trusted, and each ALG44 is supplied complete with a calibration certificate for compliance and service record purposes.

Connecting to any standard air compressor via a 1/4" BSP taper female inlet, the ALG44 slots seamlessly into existing workshop setups with no additional adaption required.

Specifications:

Ideal For: Garage forecourts, tyre fitting bays, transport depots, and commercial vehicle workshops where a hands-free, lock-on inflator with documented calibration accuracy is required for daily professional use.

Q: What is the difference between the Draper Expert ALG44 and ALG43? A: Both are MK4 versions of Draper's professional Hi-Flo inflator with the same industrial build quality, larger viewing window, and calibration certificate. The key difference is the connector type — the ALG44 features a lock-on connector that clamps to the tyre valve for hands-free use, while the ALG43 uses twin open-ended connectors for rapid attach and detach.

Q: Why choose a lock-on connector inflator over an open-ended connector? A: A lock-on connector clamps securely onto the tyre valve and stays in place without being held, freeing both hands to manage the hose and gauge during inflation. This makes it particularly suited to professional tyre fitting bays and transport depots where speed and control are equally important.

Q: Does the Draper Expert ALG44 come with a calibration certificate? A: Yes. Every ALG44 is supplied with a calibration certificate, providing the documentation needed for professional compliance records and workshop quality management requirements.

Q: What compressor fitting does the Draper ALG44 use? A: The ALG44 connects to any air compressor via a standard 1/4" BSP taper female inlet, making it compatible with the vast majority of professional and trade compressor setups.
