Features
• Aerodynamic valve design.
• Flow area of the RF nipple is up to 2-1/2 times larger than
industrial interchange nipples.
• Flow rates on 1/4” greater than many 3/8" body size couplers.
• Flow rates on 3/8” greater than many 1/2" body size couplers.
• Coupler sleeves are nickel-plated steel and coupler bodies
are solid brass construction for excellent corrosion
resistance. Standard RF nipples are manufactured from solid
steel bar stock, case hardened and Chromium-6 Free plated
.
• Dependable ball locking mechanism allows a swiveling
action to reduce hose torque.
• Push-To-Connect design for easy one hand connection.
• Integral sleeve guard to protect against accidental
disconnection.
• Wide range of port options available.
• More efficient use of compressed air due to higher flows
and reduced pressure drop.
• 1/4” body size interchanges with Rectus 25 and Cejn 320 series.
• 3/8” body size interchanges with Rectus 27 and Cejn 410 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
up to 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 couplings in the market
today. The benefits to the end user are increased tool
efficiency and decreased air costs.
