Having disasembled the drum of my electrolux washing machine (to replace drum bearings, on re-assembly, the connection from the drum to the pressure switches has started leaking. This is like a 25mm rubber (or similar) grommet with a foam separator attached, to which is attached the thin pipe to the pressure switches. I've removed the 'grommet' from the hole in the drum and cleaned the surfaces, and am considering how to guarantee (FSVO) leaks from the (elderly and probably hardened) grommet. Three thoughts are
1: rubber solution (cycle repair kit)
2: Fernox LSX
2: Silicone glazing sealant
I don't want a reaction between the grommet and the sealant causing it to perish.
Which (or what else) would the assembled expertise recommend?
