you can get QD's with out a popit in them for an open flow.......but like Doug said if your not careful on how you lay things down you are looking got trouble....one bump of the shut off and you will have water flowing every where...........
Bane uses an open male connector on their solution lines. However they run very low pressure (170psi static, 50psi running) and only moderate heat(<160 F). They do it to minimize pressure drop and maximize flow, given the limits of electric motors they used.
