Sleeve type couplings, such as Parker RF Series, are widely used to connect air lines. Parker RF Series Couplings can also be used with low pressure fluids.
RF Series has been designed to increase the flow-through, and reduce the pressure-drop over the coupling. This, along with a specially designed coupler valve, allow tremendous flow through a coupling with an envelope size of current couplings.
The benefits of the RF Series couplings to the end user are increased tool efficiency, and decreased air costs.
Common applications: compressed air, water, grease, paint, limited vacuum and limited gases.

RF Series Couplings Features
- Aerodynamic valve design
- Up to 2.5 larger flow area than industrial interchange nipples
- 1/4" RF coupling flow rate greater than many 3/8" couplers
- 3/8" RF coupling flow rate greater than many 1/2" couplers
- RF coupler sleeves are nickel plated and coupler bodies are solid brass - excellent rust protection
- Standard RF nipples are solid steel bar stock, case hardened and Chromium-6 Free plated
- Ball locking mechanism allows swiveling action while connected - reduces hose twist
- Push-to-connect for one-hand connection
- Sleeve guard protects against accidental disconnect

When ordering quick couplers, consider the following:
- Functional requirements of the coupling
- Maximum working pressure of the application
- Coupler seal & body material compatibility with the system’s fluid
- Is the application static or dynamic?
- Size of coupler & hose
- Maximum allowable pressure drop
- Requirement to connect & disconnect under pressure
- Media temperature
- Ambient temperature
- End configuration requirements
- Need for industrial interchange QC
- Effects of air inclusion & fluid loss
