M-Spa Filter Cartridge BASE ONLY
MSpa screw in base for the latest 2020 spa hot tub filter cartridge. If you have a 2020 MSpa hot tub, it would have already included this part in with the packaging.
Pre 2020 MSpa hot tubs:
The original filter cartridges for pre 2020 spa's would have had this adaptor built into the cartridge so you will need this adaptor when purchasing the new style filter cartridges to be able to fit.
PLEASE NOTE: Images 2 and 3 are for illustration purposes. This listing is for the screw base only and the filter cartridge shown are available separately as a twin pack.
