Not sure whether to choose Open or Closed flow?
✔ Choose Open Flow if you control airflow at the source:
- Battery-powered inflators (Milwaukee®, DeWalt®, etc.)
- Trigger guns or foot pedal compressor setups
- Inflator gauges and automatic inflation systems
✔ Choose Closed Flow if you connect directly to a compressor:
- Direct compressor or air hose with no trigger control
- Multi-hose inflation kits
- Constant-pressure systems where air must stop off the valve
