OYHP01 Dual-Mode Hand-Held Vacuum Pump

OYHP01 is a hand-held vacuum pump with a built-in selector switch that toggles between negative pressure and positive pressure modes. This dual-mode capability means one compact tool can be used for both brake bleeding operations and for testing vacuum-operated components such as EGR valves and sensors.

The body houses a single-hand pumping mechanism that generates sufficient vacuum or pressure with relatively low effort, making it suitable for use in awkward positions under the bonnet or beneath the vehicle. The integrated pressure gauge provides a continuous live reading during testing.

The negative pressure range covers 0–30 PSI and the positive pressure range covers 0–60 PSI, spanning the typical requirements for most automotive vacuum and pressure diagnostic tasks. Calibrated scale markings allow the technician to set and hold target values.

OYHP01 comes supplied with a selection of adapter tips and bleed fittings that connect the tool to the majority of vehicle brake nipple sizes and vacuum port diameters. The kit packaging keeps all adapters organised and immediately accessible.

This tool is appropriate for auto repair professionals and vehicle enthusiasts who carry out their own brake maintenance, emissions system checks, and component leak tests. Its compact size and self-contained design make it easy to store and transport.
