This replacement component is a Black Notched 3 5/8" Spa NON Buttress Diverter Cap only.
Important: This is a NON Buttress Cap design. If your original cap has "Buttress" stamped on it, you will need the Buttress version available separately at SpaShopper.
This Diverter Cap installs directly onto your Diverter Valve with the valve stem protruding through the center, then the control handle mounts into the square opening on top of the stem.
The Diverter Valve assembly that accepts this cap component controls water flow direction to different zones of your hot tub and is compatible with numerous spa brands.
Precise measurements: Outside diameter of cap measures approximately 3 5/8", internal thread diameter measures approximately 2 3/4", and the center stem opening where stem and o-rings fit measures approximately 3/4".
This listing includes the Cap component only. All additional parts shown in images are for reference purposes and available separately. SpaShopper carries matching handles in various colors and styles, plus o-rings, stems, and complete valve assemblies.
IMPORTANT NOTE: In some cases, replacing only the cap may not resolve issues with the cap repeatedly blowing off under pressure. If the problem persists after cap replacement, the complete valve assembly requires replacement. Full valve kits are available at SpaShopper.
