Summary
The APEX Design USA Open Flow Spring Stop converts a High Flow Push-On Chuck from closed flow to open flow. Open flow passes air straight through for the fastest possible fill - the mode you want when a compressor is doing simple single-tyre work and nothing in the line needs to hold pressure.
Best For
- Push-on chuck owners converting to open flow for outright fill speed
- Replacing a lost or worn open flow stop

Fitment And Setup Checks
Confirm your chuck is the APEX High Flow Push-On model before ordering. Remember open flow will not hold line pressure - switch back to the closed stop for gauge or multi-tyre work.

Frequently Asked Questions
Open or closed - which do I need?
Open for the fastest simple fill; closed whenever the line must hold pressure for a gauge or shared system. The two stops convert the same chuck either way.
Keep both on hand with the closed flow spring stop.
