Full Product Description

RF Series Couplers (pneumatic, air) up to 300 psi connect with RF Series Nipples and are interchangeable with common High Flow European couplings. Parker's rapid flow couplings are push-to-connect, single shut off quick couplings.

1/4" RF Series functionally interchanges with Rectus 25 and CEJN 320. 3/8" RF Series functionally interchanges with Rectus 27 and CEJN 410.

Couplers have an aerodynamic valve designed for increased flow. The flow rates on the 1/4" size are greater than many 3/8" body size couplers and the 3/8" size flow rates are greater than many 1/2" body size couplers. The increased flow results in greater tool efficiency and decreased air costs.

High flow couplers are also used on breathing air lines and respirator equipment used in paint booths, chemical laboratories and similar environments.

Technical Characteristics:
• Sizes: 1/4”, 3/8”
• Materials: Brass body with nickel plated steel sleeve
• Port Ends: Female NPTF, Female NPSF, Male NPTF, Standard Hose Barb, Push-Lok Hose Barb
• Seal Options: Nitrile, Ethylene Propylene, Fluorocarbon

Markets:
