9/16 Autococker and VLM Tornado Valve
AKA Tornado Valve 9/16 with replaceable cup seal. These were redesigned for the 2016 Twister Cocker run and were released then.
Now they are available in Classic .575" diameter as classic spec bodies from 2000 and older Cockers and all VLM bodies. Now Mini .560" diameter fits 2001 and newer spec bodies like Empire and Inception. The mini will work on the older bodies also. The Classic was made to original production bodies.
