Fleck (17772) Silicone Seal
Fleck 5600 Silicone Seal (Model 17772)
Factory-spec seal for Fleck 5600 control valves. Prevents leaks at the piston assembly and maintains proper valve cycling pressure.
Critical seal for piston operation
The Fleck 17772 silicone seal sits inside the control valve piston assembly and creates the hydraulic pressure differential that allows the valve to cycle through backwash, brine draw, and regeneration. When this seal wears out, you'll see leaking around the valve head or erratic regeneration cycles. This is the factory replacement part.
