Parker MD Series Quick Coupling is a coupling system for the medical field in POM of USP class VI with the world's most popular profile in this nominal diameter. Series MD stands out for its above average flow performance for liquid and gaseous media.
This coupling system is developed for single-hand operation. The new type of plastic locking system with handy sleeve considerably expands the applications. The color and mechanical coding of the coupling and plug offers a guarantee for avoiding mix-ups between media when coupling. The coupling is also available straight-through (with no valve). Quick coupling system with nominal diameter 5 for medical applications up to 10 bar. Available made of thermoplastic (POM).
