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.
