The Valken Proconnect is an essential accessory for any player using a remote line. Using the Valken Proconnect will allow players to connect and dis-connect the remote line while it remains under pressure. Simply press the button to dis-connect and just push the fittings together to connect. It is the easiest way to detach the remote line from the gun without having to depressurize. The Valken Proconnect is very reliable and doesn't require any tools for service. There is only one o-ring that ever needs to be replaced.
