Full flow service work

Valve cores can reduce recovery and evacuation performance.

Valve cores are designed to restrict flow and minimise refrigerant loss. During recovery and evacuation, that restriction can slow the job down significantly. Removing valve cores helps maximise flow through the system access port.

Through valve core Approx. 5.7 L/min / 0.2 CFM
Core removed Higher flow for faster evacuation

Magnetic base and adjustable tip

Built for practical field handling.

The magnetic stem base helps secure the stem to metal surfaces so it is less likely to be misplaced during service work. The adjustable tip can be tightened or loosened to suit various valve core sizes and improve grip during removal or installation.

Stem Base Magnetic
Stem Tip Adjustable
