Multi-Coupling (MMK2)

The MARTIN Multi-Coupling serves as a connecting element between machines and attachments. The MARTIN Multi-Coupling MMK2 is a system for connecting two hydraulic lines by means of single lever movement. The hydraulic reaction forces are absorbed by the coupling housing.

The MARTIN Multi-Coupling MMK2 has been designed for rough on-going site operations and is practically leak free. These couplings are equipped with residual pressure eliminators as standard. This ensures a coupling of pressurised systems with the minimum of effort.
