Jet Body worked great to replace older body on a Master Spa Cape Cod 2005 converting to a threaded body and threaded Jet style. Spacer ring was used with the Cape Cod to keep the Jet body centered while tightening the nut due to hole size/slippage. Gasket included worked great. No leaks. Installers were experienced service techs. Part was affordable compared to a dealer quote ordering through Master Spa.
