We're consistently asked how players can add an on/off valve to their paintball setups. Here is the answer. The Rap4 AG1 On-Off Adapter can be used with any paintball Co2 or HPA bottle. It easily screws onto your bottle and then also screws into your markers ASA or tank adapter. You can then use the knob to control whether or not the paintball bottle will be pressurizing your marker. Meaning you can finally leave your tank on your marker all the time without having your marker constantly pressurized. This adapter has a gauge for up to 1500 psi of output pressure.

This is a great upgrade for players whose markers have internal gas lines (X7 Phenom, Cronus, Gryphon, FT-12, and more) as you do not need to upgrade your tank adapter (ASA).
