Fresh from our Metal work shop these brass fittings are for the leva Europiccola models post 2000 and pre 2000.
Due to the time taken to set up the lathe to turn the male thread takes time so the cost is higher than normal metal lathe work.
This part is only to be fitted / guaranteed if a competent mechanical person is fitting. We will not accept damaged returns by buyers not fitting correctly after reading below
Only use medium strength thread lock NOT plumbers tape as male thread is not designed and only excepts a minimal amount of thread lock liquid to position the fitting ( do not over tighten brass/ stainless steel fitting as there is no need !Use the thread lock and therefore allow the components to dry.
