Parker Quick Couplings
Dry Break Quick Coupling with Parker Profile, Series 204

Dry break quick coupling system with nominal diameter 4 for pneumatic and fluid handling applications in sensitive environments up to 15 bar. Available made of brass or stainless steel.

 

 

Parker's dry break coupling system has been developed for applications in sensitive environments, for example in analysis technology, in cooling systems, in transport systems and many applications with aggressive media.
This coupling system with single-hand operation has extremely low leakage rates and minimal dead space volume. The design allows absolutely no air pockets when coupling and only a barely noticeable film of the medium being channeled on the valve bodies when uncoupling.
