RF Series Pneumatic Couplers are designed to increase flow
and reduce pressure drop through the coupling. RF nipples
have up to 2-1/2 times larger flow area than standard industrial
interchange nipples. The increased flow results in greater tool
efficiency and decreased air costs. Couplers have brass bodies
with nickel plated steel sleeves. RF nipples are steel.
Features:
•
Aerodynamic valve design
•
Steel nipples are case hardened
•
Flow rates on 1/4” is greater than many 3/8” body size
couplers
•
Flow rates on 3/8” is greater than many 1/2” body size
couplers
•
Integral sleeve guard protects against accidental
disconnection
•
Functionally interchanges with a common high-flow
European design. 1/4 RF interchanges with Rectus 25
and CEJN 320. 3/8” RF interchanges with Rectus 27 and
CEJN 410
•
Standard seal is Nitrile
Applications include:
•
Air compressors
•
Pneumatic tools
•
Drop-down air lines
