I am thinking about a brewery upgrade and but need to sell my current QDs in order for me to justify my next purchase. So...
I have about 12 sets of polysulfone quick disconnects. These QDs are a popular style for homebrewing. They are rated for 280 degrees, and are 1/2" barbed on one side and male thread on the other.
They are in excellent condition and I am asking $17 per set. For a set they go anywhere from $20 - $30 brand new plus tax and shipping.
Let me know if you are interested.
