Graded Seals Exporter

Graded seals available for Export

Moores Glassworks are a world leader in the manufacturing of graded seals.

A graded seal is used to overcome the difference in coefficients of thermal expansion. This is done by using a series of intermediate sealing glasses between the two different glasses on each end. The linear coefficient of expansion must be close to avoid these seals from cracking.

Using special and unique techniques, Moores Glassworks manufacture over four thousand various grades per month at our production facility in England. Our experience in providing graded seals has enabled us to offer a wide range of products suited to applications in scientific, analytical and military industries. Moores Glass can rely on their highly skilled team of glassblowers as well as state of the art tools and machinery.
