Description
Genuine Gray Notched Buttress Style Diverter Cap measuring 3 3/4" across - replacement cap only included in this listing.
Important identification step: Examine your existing cap carefully for the word "Buttress" stamped into the plastic. Reference our product images to see exactly where this marking appears on authentic Buttress Style caps.
Caps without the Buttress marking require a different Non-Buttress version available separately at Global.
Installation overview: This cap secures directly onto your diverter valve housing with the control stem protruding through the center opening, then the control handle attaches to the square stem top. These diverter valves regulate water flow direction between various spa zones and are found across numerous hot tub manufacturers. Precise dimensions include: outer diameter approximately 3 3/4", internal threading approximately 2 3/4", and center stem opening with o-ring seating approximately 3/4". Compatible with multiple spa brands featuring gray-colored plumbing components.
Package contents: Cap only. All additional components shown in photos (handles, stems, o-rings, complete valve assemblies) are displayed for reference purposes and are available as separate purchases from Global.
IMPORTANT TROUBLESHOOTING NOTE: In some situations, replacing only the cap may not permanently resolve caps blowing off under pressure. If the new cap continues releasing unexpectedly, the complete valve body likely requires replacement. Global carries full valve replacement kits for this purpose.
