IBC Water Tank Adapter 1" Coarse Thread S60X6 Connector Water Butt Fitting Hose Tank Full Flow Barb Oil Fuel

Leaks between cap and brass fitting. IBC cap looks to be from soft platic. I hand tightened, it leaked, kept tightening with a wrench until leak stops. Brass started cutting into the plastic cap, but leak never stopped. Its a drip now, but still.Will give it 2 stars because the brass parts appear good.

It doesn't come assembeled and it doesn't fit a standard 1000L IBC tank
