2 x Stem/Shaft O'Rings and 1 x Top Cap O-Ring to suit Waterway, Hydroair, CMP 2" Spa Hot Tub diverter valves. May also suit many many more, as 90% of all diverters are a copy of Waterway or Hydroair valves.

These diverters are used on Monarch, Maax, Bullfrog, Leisurite, Signature, Sapphire, Designer, Cyclone, many Chinese, and many many other brands.

Large O-ring: ~66-67mm outside diameter | ~61mm inside diameter | ~2.6mm cross section
Small O-rings: ~19mm outside diameter | ~14mm inside diameter | 2.6mm cross section

Note: On some older diverter valves, the top of the diverter body can shrink or warp over time. This can make the o-ring under the cap very difficult, or even impossible, to fit back in correctly. If that happens, you have two options:

• Try using slightly smaller o-rings from a seal supplier to get a workable fit
• Replace the complete diverter valve and body
