Parker ZoomLock braze-free fitting coupling PZK-C4-HNBR 1/4''

The ZoomLock™ pipe connection system is an innovative system for joining pipes without the use of solder and is suitable for any refrigeration and air conditioning application. Pipes can be joined with a simple tool and using minimal force. 

ZoomLock™ fittings allow properly sealed pipe connections to be made without using solder, making it much faster and easier to join copper pipes. These single-piece fittings also stay reliably in place, are leak-proof and offer better reproducibility than solder connections - meaning no compromise needs to be made on quality or functionality.
The time needed and costs of work for connecting pipes are significantly reduced by not having to solder. Solder-free pipe connections increase productivity, profit potential and offer numerous other advantages.
