Your cart is empty.The Fleck 2510 & 9100 tank O-ring (18303) is commonly replaced to fix leaks that develop at the base of the control valve where the valve seals against the tank. It may also be necessary to replace the slip ring (19197) if it is cracked, which will allow leaks in the same area. This is a genuine Fleck part that will work on all Fleck 2510 & 2510 SXT, softeners, filters, and air injection valves AND 9100 & 9100SXT softener valves, including the O-rings on the second tank adapter.

I used this to replace my original part between the Fleck valve and spun fiberglass tank. Works well, no leaks.

Exact fit, just as described. Way better than driving to several plumbing stores trying to find a replacement.

Exactly what I needed to reinstall my Fleck 2510sxt back on the tank. Had to order a slip ring as well, now everything is back up and running.
