I'm considering the purchase of a Blichmann TopTier brewing setup and a March Pump. In the process I've looked at several different disconnect options for the tubing to connect all of this together.
I stumbled across Pro Flow Dyamics Cam and Groove Stainless Steel Coupling system. These appear to be high quality stainless disconnects at a great price and I just ordered a few.
I plan on using my current tri-clamps for connection to the pots and rims tube but I will use these mid-line in the hose to switch connections to the pump, sparge arm, etc.
In the process of communicating about these with Pro Flow Dynamics, they generously offered a 10% discount to homebrewers.
Use coupon code 10%proflow to receive the discount. This is supposed to be valid for the next couple of months.
