silicone gaskets

[Bob Kneale]

Yes Jon and they work well on sumps.

I may have a declared interest, having written the original article, but having had to replace the silicone  sump gasket with a 'posh cardboard' version in an emergency, I have found the replacement item has resulted in leakage again. I will be replacing said gasket at the earliest opportunity.

Bob Culver's comment about hub gaskets is partly valid, but the gasket squishes down sufficientlly to take up the necessary clearance, and I've not had any problems with  material of that thickness.

It's a case of 'Horses for courses' and there are many situations (mainly high stress/temperature) where such materials would be obviously unsuitable - although I await with immense interest news of a silicone rubber head gasket

My source of supply of this material has seemingly disappeared of the radar (to my embarrassment) and I would appreciate any info on an alternative source.

I look forward to your comments - most of my posts seem to terminate subsequent threads. Please don't imagine me as some sort of guru

Used gaskets may need 'drying out' to regain their original dimensions, but this property seems to happen after about a week, and must be due due to solvent absortion or something!

Good luck with your endeavours

Bob

Hoping the appaling Cornish weather will end!
