Which 1/2" nut driver worksfor Balanced Valve?

[iamthelazerviking]

I've read a lot about different 1/2" nut drivers not working properly with the Nova Balanced valve, so wondering which one(s) DO work.

Contemplating an NX1 Sentinel sniper and want the tool on hand.

I used these to install mine: https://www.harborfreight.com/hollow...ece-69239.html. Can't beat the price either.

if you have a 3d printer you can make your own Autococker valve tool with Nova valve adapter by gilbertcerna - Thingiverse
