Review on Wet Line Hydraulic Disconnect Coupler Coupling by Tony Wilson

This coupling is great. I needed something to separate my fuel tank from my pump truck that had enough capacity for diesel fuel to flow freely and also latched securely so I could trust it with fuel and it worked great. If the valves are pushed apart there is a 0% chance of leakage, they are VERY tight. The only thing to note is that they are very heavy, but I would trust them to connect and disconnect under pressure with fairly thick liquids.
