Install this Fast Flow valve on your horn. This valve when in the open position, has a straight-through 17/64 inches diameter hole for the fast flow of powder. The valves will accept standard flask spouts or the pouring adapter. A pour spout and bushing are sold sold separately.

The flask valve was exactly what I needed. I was having problems with my old powder horn valve, it would not pass 2ffg without a lot of shaking. This valve allows free flow of 2ffg powder without any shaking.
