HeadSeal Premium Impeller and Seal Kit Compatible with Best-Way Lay Z Spa AirJet Models – Replacement impeller and Seal Parts for Lay Z Spa Hot Tubs, Enhanced Water Flow and Leak Prevention.

worked a treat, saved me a load of money.

I would not recommend stick to standard version.The silicone is to thick and the large seal is a little big.I worked around this issue with the help of bath sealant.You end up with a gap all the way round your impeller unit.Also the rubber on the ends of the impeller stick is a different shape at the bottom.I've gone from the sound of clicking from my old impeller to another odd sound since replacing it with this kit.As soon as this one starts playing up I will be ordering one of the other standard version of this kit off Amazon has I've never had this problem with those.

Fitted perfectly best out all the ones I have tryed
