I have been trying to help a friend avoid unnecessary expense replacing a "spider" gasket seal in a filter housing . Although it looks fine and is fairly supple it does appear to be allowing water in areas it shouldn't . I have removed the gasket and thoroughly cleaned all surfaces but the leakage continues . I cannot tighten anything further but wondered whether rather than ordering a replacement at £60 a pop (and possibly finding no improvement) I was considering using something along the lines of silicone sealant to smother the gasket and contact areas and hopefully improve things at minimal expense. Would anyone know whether this sounds like a good or bad idea and whether a different sealant might work better such as a polyurethane type construction sealant or similar . I won't be apply a huge amount in case it breaks off and causes a blockage . I have also wondered about filling the "tray" where the gasket sits ( it is the same shape) full of sealant ..leaving it a little proud ...then allowing it to cure and clamping the lot down .

Any input,suggestions, advice would be much appreciated, thanks in advance,

Bill

So, fresh water on one side, what's on the other? Air? What sort of operating temperature and pressure are we talking about?

Yeah, not enough information. What's it for? Have you buggered the seal by overtightening it? Have you tried Gummi Pfelge or Vaseline on it? Can you use gasket paper or even instant gasket instead?
