1.05 Top Distributor Twist On Style used on Newer ( since 1997 ) Fleck, Clack, and Autotrol Control Valves. D1203 top distributor fits the Autotrol ( Pentair, GE Osmonics ) 255 since 1997.And recommended for all Performa ( 263 and 268 )Customer Comment / Question: I am installing the distributors and it almost seems the top is meant to twist the wrong way. There are two lips in my valve preventing it from turning but seem like there would be room if it spun the other way, do you have suggestions before I trim the plastic?
