APneumatics General Purpose � Push-To-Connect Pneumatic Quick Couplings RF Series Description The Parker RF Series pneumatic couplings offer the quality and dependability customers have come to expect from Parker's line of pneumatic quick couplings.The RF Series has been designed to increase the flow through and reduce the pressure drop over the coupling.The nipple design has a 2-1/2 times larger flow area than standard industrial interchange nipples.This, along with a specially designed coupler valve, allows tremendous flow through a coupling with an envelope size of current 1/4" couplings in the market today.The benefits to the end user are increased tool efficiency and decreased air costs.
