outlet fittings on the back of the K682-2 Kit. Connect
the other ends of the hoses to the appropriate ports on
the water cooling units.
2) In the event the water line fittings on your water-cooled
gun are incompatible with the female quick connects
on the front of the K682-2 Kit, male quick connects are
provided with the kit for installation on 3/16” (5mm) I.D.
