The FF range of quick release couplings from Stauff provides three sizes (nominal width from 6 to 38) for connecting the hydraulic circuits of construction machines and attachments. They provide minimum risk of a leak and no ingress of air into the hydraulic circuit. The term flat-face is a key feature that enables the coupling halves to be easily cleaned and prevent contamination and dirt.
The dimensions and contours of the couplings are compliant with ISO 16028 to ensure universal compatibility. The integrated interlocking is a safety feature that allows the user to firmly lock the loose half by turning it 90° after connecting the coupling halves. Consequently, an unintentional loosening of the coupling is literally impossible.
