1.05 Top ( Upper ) Distributor Twist On Style used on Newer ( since 1997 ) Fleck, Clack, and Autotrol Control Valves.
Also, Replaces Fleck p.n. 18280 collector, top, 1"x.011, gray
This Upper Distributor Screen is included with each Complete Valve ( but not if you order just the lower body or tank adapters ). and Water Softener we sell.
MD1203 top distributor fits the Autotrol ( Pentair, GE Osmonics ) 255 since 1997.
And all Performa ( 263 and 268 ) if you file off two of the notches
( Performa only uses 2 of the 4 possible slots ).
You can use our
PN 23D1203 for the Performa 263 and 268 valves, with no modifications needed.
The Autotrol 155, 1550-TC and older 163 or 168 would not have the snap in slots that work with this Top Distributor. And they require that you purchase the "glue" version, which would be 13/16" for 155 models, and usually 1.05" for the 163 and 168.
Fleck models ( since 1997 ) of the 5000, 5600, 2510 and other Noryl Plastic valve bodies would have the "slots" for using this top distributor ( MD1203 ).
Older models used "glue" version, again it could be 13/16" for some older models, or 1.05" ( the size of the opening for the center pipe ).
INSTALLATION:
Slots of the Top Distributor - Line Up Slots - Should "drop" into place - then TWIST,
Pushing down while you TURN - Counter Clockwise to LOCK into place.
