Series FF/FH

A flat face hydraulic push-to-connect coupling is a special coupling that allows little to no fluid to escape when uncoupling and at the same time prevents dirt or air from entering the hydraulic circuit. STAUFF FF series couplings are of this type and comply with the flat face standard in accordance with ISO 16028.

STAUFF FF series hydraulic push-to-connect couplings are preferably used in mobile and stationary hydraulic systems, e.g. in

• Construction machinery

• Agricultural and forestry machinery

• hydraulic attachments

• Stationary hydraulics

Thanks to their robustness, flat-face design and one-handed operation, they are ideal for harsh operating conditions.

The most important advantages:

• Minimised risk of leakage when uncoupling

• No ingress of air or dirt into the hydraulic circuit

• Simple one-handed operation without tools

• Long service life thanks to zinc/nickel corrosion protection

These properties make the FF series particularly easy to maintain and efficient in operation.

Yes, the flat-face STAUFF FF hydraulic push-to-connect couplings are manufactured in accordance with ISO 16028 and are therefore interchangeable with many standard flat-face couplings from other manufacturers on the market - both in terms of dimensions and function.

The STAUFF FF series is available in nominal sizes DN 06 to DN 51 - this corresponds to connection sizes from 1/4" to 2". They therefore cover a wide range of applications for hydraulic hoses and pipes.

Yes, when used with STAUFF FC series coupling plugs, the couplings can be coupled under residual pressure on the plug side - up to 250 bar. This makes them particularly practical for applications with hydraulic attachments.

The FF couplings are made of high-quality steel and have a zinc/nickel surface coating. This ensures a high level of corrosion protection - even for long-term outdoor use or under demanding conditions.

STAUFF FF hydraulic couplings are available worldwide via the STAUFF sales network and online from specialised dealers. Thanks to high stock availability, they are generally available at short notice.
