Ball lock replacement valves

[gazandy]

Can anybody help . I’m trying to convert a recently purchased Cornelius keg from pin lock to ball lock . I purchased the new valves
9 1/6 x 18 from Amazon using their keg identifier but they’re too big . The name on the top of the keg is SAFER does anybody know what size conversion ball lock I need and the best place to get it from ? Thanks in advance Gary
