ON/OFF ASA Adapter with Integrated Pressure Gauge for HPA Tanks – Fast Degassing & Pressure Control | Compatible with Umarex T4E (.50 / .68)

ON/OFF ASA Adapter with Pressure Gauge for HPA Tanks – Safe Degassing & Pressure Monitoring

The ON/OFF ASA adapter with integrated pressure gauge from Homedefence-24 is a robust steel adapter installed between the HPA air tank and the Umarex T4E platform (.50 and .68 caliber). It allows safe shutoff of the pressure supply and fast degassing of the system so the tank can be removed without residual pressure and without damaging threads or seals.

Integrated 0–1500 psi Pressure Gauge

The built–in pressure gauge displays the current output pressure from 0 to 1500 psi, allowing shooters to monitor performance during tactical scenarios, training or defense applications.

How to Use

• Turn the valve to the OFF position.
• Fire 2–3 shots to safely release residual pressure.
• Unscrew the tank without force and without pressure on the threads.
• The tank can remain attached – in OFF position no air flows into the system.
