Parker’s Quick Coupling Series 608/612 (French series) has been specially developed for cooling in the field of plastic injection machines / molds. By using vertical plug inserts, the cooling connection can be installed directly in the mold / machine, so the external contour has no protruding extension components. This allows easy and safe handling during the work process and prevents damage to the coupling and the mold.
This system is supplied as a “straight-through coupling“ with no valves. The coding of the in and outlets can be represented by simple fixing of the colored clips / rings onto the coupling and plug.
The use of the locking balls means that an optimum grip of the plug connection is guaranteed, even with forces that are applied laterally. The simple unlocking mechanism, which is optimized by knurling at the end of the sleeve, can be operated by pulling back once on the sleeve.
