Today I went to my local hardware shop and searched for a good and hard rubber for the sealing face of my piston but there were only some black, quite soft rubber sealing gaskets and some paranite ones. The soft ones work for lower pressure, but how about paranite? It was quite hard...

best way to find out is to try it.


edit: quick Google search and it looks like its made from asbestos. i would suggest against it.

I dont know where you are from, but Lowes sells this stuff, its a reddish orange color, for a 8" x 8" piece its only like $1.59. Works quite well in my opinion, but does need to be replaced after time

Paronite seems to be made of compressed asbestos. Don't use it, unless you want lung cancer.

Thats bad. I can't really find anything as hard as paronite, but I have some kind of other sealing gasket at home so I'll check that. Anyway, a solution can be found!
Thanks for the info!

If what your using is paronite then better don't, as everybody else suggested.

What mattyzip77 is referring to is generic gasket material. It's as good as anything for a sealing face. If that isn't good enough, look into using a high-durometer thick o-ring.
