The LinkTech 60PS Series is a lineup of premium plastic Quick Disconnects.  These High Quality QDs are made from medical grade polypropylene, a high-strength plastic that is temperature tolerant 160° (Max!), and can handle pressure ranging from a vacuum to 60 psi. All of the 60PS Series will interconnect, and these units will also work seamlessly (and leaklessly!) with CPC Quick Disconnects of the same internal 3/8” flow path.  O-rings are a EPDM Rubber, and internal valve springs are constructed from 316 Stainless steel.

This is a Male Plug, which can connect to any H501 Series Female Socket.  It has 1/2" Male NPT threading for use with any products equipped with 1/2" Female NPT.  This QD is equipped with a shutoff valve.   When not connected to another QD, this will not allow any flow. 

While not quite as bulletproof as our Stainless Steel Quick Disconnects, this lineup does offer a few advantages.  These can be set up with Shutoffs, which will prevent flow when disconnected, and can be incredibly useful on Pump or Glycol systems.  The pricing of these products is more economical, yet the plastic is still medical grade.  All in all, these are a premium lineup of quick disconnects with great features and lots of options.

Clogging issues
I tried to create a dry disconnect to my counterflow cooler using pairs of male & female QDs with shutoff valves and learned two important things: First, the valve mechanism reduces the bore, so it is not a full-flow fitting, which is a consideration if using in a cooling loop. Second, the spring-loaded plunger mechanism is very prone to clogging by any hop or cold break material - this both interferes with flow AND can result in leakage when disconnected due to the plunger being unable to fully close. These QDs work, but be aware of their limitations . . .
