Glass to Metal Seals

Another of the unique and highly specialised items we at Moores Glasswork produce and export are glass to metal seals. These are matched seals comprising kodial glass which is sealed directly onto an iron-nickel-cobalt alloy (Kovar) tube that has a near identical coefficient of expansion. A graded seal is thereafter fabricated to Pyrex glass. These Kovar-Pyrex type glass to metal seals can be manufactured in a range of sizes from 1/8″ to 6″.

We are also able to manufacture extended seals featuring a quartz termination as well as in non-standard diameters, which we produce by using sheet material to form the 'Kovar' sleeve. Moores Glasswork can also supply seals welded into vacuum flanges. If we haven't mentioned what you need, contact us to see if we can fabricate it.
