Series 2FSI flat-face couplings contain special sectors made of hardened steel rather than latching balls to increase the contact surface between male and female couplings, preventing the brinelling effect.
This also reduces load and increases life. The couplings come in sizes , , and 1 in. (ISO 16028 interchangeable) as well as 1 and 2 in. for heavy-duty applications. The devices resist highfrequency pressure cycles, flow peaks, and dirty environments.
