Made by Waterway
This part will fit Imperial 2" flexible, rigid pipe and male fittings on your spa / hot tub. Waterway Diverters can be used for many things on your spa, replacement caps, handles and diverter cups. The inside of a Waterway diverter has 3 seals, 2 which stop the water coming up and out through the handle hole and 1 which seals the cap onto the collar.
Unfortunatly these parts do not come as seperates, but they do seem to be universal and fit on chinese hot tubs as well as American and Canadian hot tubs and spas. Most commonly seen on Spaform hot tubs and Canadian Spas.
note the do not fit Hotspring spas, Dimension 1 hot tubs, Arctic Spas and Sundance hot tubs
