Description
This replacement O-Ring is engineered exclusively for Pentair 5" diverter valves featuring a 4 3/4" wide cap. As this diverter model is being phased out by the manufacturer, replacement components are becoming increasingly limited. Global carries remaining stock of select parts and complete valve assemblies while supplies last.
Designed to create a watertight seal on the diverter valve cap, this O-Ring ensures proper operation and prevents leaks in your spa plumbing system. If your Pentair 5" diverter requires additional sealing components, the undercap gasket and stem O-rings (O-643) are also available separately.
COMPATIBILITY WARNING: This O-Ring is NOT compatible with 2" Waterway, Hydro-Air, or CMP 2" valves. Those models use caps measuring between 3 11/16" and 3 3/4" and require different sealing components.
Verify your existing diverter valve cap measures 4 3/4" wide before ordering to ensure proper fitment.
