Parker RF Series Pneumatic Couplings | General Purpose - Push-to-Connect

Parker RF Series Pneumatic QC

Parker RF Series couplings are an aerodynamic valve design with a wide range of port options available.

Flow area of the RF Series nipple is up to 2 1/2 times larger than industrial interchange nipples. Flow rates on 1/4" are greater than many 3/8" body size couplers. Flow rates on 3/8" are greater than 1/2" body size couplers.

RF Series 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, which are case hardened and Chromium-6 Free plated.

Rf Series interchanges with a common high-flow European interface.

Standard seals are nitrile. Optional materials are available - contact us with questions.

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.

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
