DIN Gasket material for sight glass?

Recommended Posts

After about 3000 distillations, the DN100 gasket on the sight glass of our still has developed a crack and needs to be replaced. The gasket sees a lot of contact with high-temp alcohol steam and also torque from removing the sight glass for cleaning. I would normally get EPDM but wanted to see if anyone had a different suggestion / experience?

Silicone is also great.  Just make sure that it is at 80 shore hardness.

We use the Buna Gaskets on ours.  It is Blue material and is great with high heat and alcohol. Try Brewers Hardware, they have a good selection.

richard are you talking about silicone in a tube 

No, you get a variety of available gasket materials be it for DIN unions, tri-clover etc.  Generally Silicone, Buna, EPDM are all available from process piping suppliers.
