The Psiworx Pro-Connect III is the latest version of a 15 year paintball favorite. Those who have used a Pro-Connect in the past know that it is an indispensable item for remote users. The quick disconnect design allows your remote to remain pressurized when you disconnect. A life saver if your remote becomes tangled in brush. This is the piece that connects to your ASA and has a 1/8 inch NPT opening. Great to keep an extra around!
