SC pneumatic swing couplings are available in nominal sizes from 14 to 34 in. and in different interchanges. Just a swing and the air is vented ensuring that the hose is ventilated, thus rendering it harmless. They are compatible with most interchanges. Pressure is always automatically off during the coupling process. They offer full flow and negligible loss of pressure and operate at pressures to 360 psi.
