Series FF flat-face hydraulic quick-release couplings

STAUFF FF series flat-sealing hydraulic quick-release couplings provide a reliable, clean and safe connection for hydraulic systems – no tools required thanks to one-hand operation. Available in various designs and nominal sizes (1/4‘ to 2’), with coupling plugs and coupling sleeves made of steel and zinc/nickel surface coating for excellent corrosion protection. Interchangeability according to ISO 16028 guarantees full compatibility. Original STAUFF quality, ideal for construction machinery, agricultural and forestry machinery and stationary hydraulics. Minimal risk of leakage, no air ingress into the hydraulic circuit and high pressure resistance make these couplings the first choice for professional applications.

Buy flat-face push-to-connect couplings of the FF series from STAUFF in the online shop

The flat-face push-to-connect couplings in the FF series from STAUFF are the ideal solution for quick, tool-free coupling and uncoupling of tube and hose lines in hydraulic systems. They consist of a female body and a male tip and impress with their reliable tightness, easy handling and high load-bearing capacity. They stand for proven quality and many years of experience in hydraulic technology.

Materials and surfaces

The FF couplings are made of high-quality steel and are designed for use in demanding environments. Their special surface coating reliably protects the flat face couplings against corrosion and ensures a long service life - even with intensive use.

  • Steel: high mechanical strength and durability

  • Zinc/nickel coating: excellent corrosion protection, even in harsh environments

  • Flat-facedesign: prevents leaks and the ingress of air into the hydraulic circuit
