What material is best to use for water tight gaskets

NOT head gasket, i need to make 2 gaskets up , 1 for water hopper inspection cover and one to join the hopper to the head block(NOT CYLINDER HEAD) what is best material to use, thanks

Ideally you need some descent gasket paper Ryan, brown paper is too thin for those applications. I get gasket material locally, I would THINK that bearing specialists, motor factors etc should stock it. Cereal packet would do at a push but I prefer the proper material. Hylomar is my favourite "goo" for sealing as it is easily removed should the need arise (and it usually does)!

Pete as said it all thats the right way to do it, the water jacket inspeaktion plate should be made of cork
Chris

but thanks for the info guys

Don't forget cork comes in different thickneses, so you'll have to see which you need.

a quick check to see what sort of thickness you need is to check the variations in level of the material you intend to seal, put a straight edge over the workpiece, and see how much distortion you have, and use thicker or thinner gasket paper accordingly.
