Homedefence-24: Professional Pressure Control for T4E Systems

The ON/OFF ASA adapter + Pressure gauge for HPA air tanks suitable for Umarex T4E guns is a high-quality accessory designed for maximum care of your gun's mechanism. This adapter is easily installed between the gun and the HPA tank. Its main feature is the ability to close the air supply to the gun at any time without having to unscrew the entire tank.

The operation is very simple: by turning the valve to the OFF position, you shut off the gas supply. Then, you fire two to three dry shots to fully vent the internal system of the gun. At this point, you can remove the tank perfectly smoothly and without force, or leave it connected to the gun – thanks to the lack of pressure, there is no risk of seal degradation or material fatigue. When needed, simply turn the valve to the ON position and the gun is immediately active.

Durable Construction: The adapter is made of robust steel with a chrome finish, guaranteeing high resistance to wear and corrosion. It includes a clear output pressure gauge with a range of 0-1500 PSI, allowing you to constantly monitor your system's status. Due to its compact dimensions (length 5.5 cm), the adapter does not disrupt the gun's ergonomics.

Technical Parameters:

  • Material: Steel, chromed finish.
  • Gauge: Range 0-1500 PSI (output pressure).

Frequently Asked Questions (FAQ):

Why should I use this adapter instead of direct tank connection?
When unscrewing a tank directly under pressure, both the threads and the seals in your gun suffer. This adapter completely eliminates this issue.

Does the gauge show the tank pressure?
This gauge shows the output pressure heading into the gun (up to 1500 PSI), which is crucial for the safe operation of the T4E system.

Is this adapter suitable for permanent mounting on the gun?
Yes, thanks to the chromed steel, it is very durable and allows you to keep the gun ready for use in OFF mode for long periods.
