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.
Features:
•
Aerodynamic valve design.
•
Flow rates on 1/4” is greater than many 3/8” body size
couplers.
•
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.
•
Integral sleeve guard protects against accidental
disconnection
•
Functionally interchanges with a common high-flow
European design
Applications include:
•
Air compressors
•
Pneumatic tools
•
Drop-down air lines
