The Proconnect3 is the latest generation of a 20 years paintball favorite. It has been updated to be serviced by the player. Replacing the valve top o-ring can now be done with no tools. We have also changed the finish to a black nickle to reduce shine and glare but maintain a smooth operating finish. Simply push together to connect under pressure and push the button to dis-connect. No more sliding o-rings. No more having to depressurize your remote. The Proconnect3 connects under pressure.
