FF Series Flat-face Hydraulic Quick Coupling
FF is a steel flat-face hydraulic quick coupling. The catalog describes a flat-face valve arrangement that reduces fluid loss during coupling and disconnection and lists sizes from 1/4 to 2 inches.
Product features
The flat-face valve design reduces fluid loss during coupling and disconnection. A sleeve-lock arrangement reduces the risk of accidental disconnection. A ball-locking mechanism joins the mating halves. The catalog states ISO 16028 conformity and a standard NBR seal.
