Single Coupling (MEK)

The MARTIN Single Coupling MEK for connecting flexible hydraulic lines. Used for connecting hydraulic hoses and lines which must transmit high forces and have extremely compact dimensions. The hydraulic reaction forces are absorbed by a simple and rigid locking device.

The MARTIN Single Coupling MEK is designed primarily for rough on-going site work, but can also be used in the workshop or laboratory. The in-house-developed single coupling has next to no leakage when coupling and uncoupling. The single coupling is produced as standard with a residual pressure eliminator. This ensures a coupling of pressurised systems with the minimum of effort. The small outside diameter in relation to the flow cross-section is practically unparalleled. The small gap dimension, the high-quality seals and materials ensure a long service life.

MARTIN Single Coupling (MEK)
