Incorporating Quick Disconnect (QD) Fittings allows you to lengthen, shorten, and clean your tubing quickly, and easily.  Made from Acetal (POM) Plastic. 
 
This is an insert plug.  You can insert this into a non-valved female QD fitting and it will stop odors and liquid from passing through the fitting.
 
We pair the 3/8 inch fittings with 5/16 inch tubing to give a secure seal on the hose barb connection without having to use tubing clamps. 
 
To use these, you will simply insert this fitting into the female QD fitting.  The two connectors will "click" into place.  To remove, simply press the button and pull the fittings apart.
 
DIY Instructions will be posted in our Blog.
 
These are plugs and are used to stop the flow of liquid through disconnected non-valved female QD fittings.
