Graded Seals and Preforms:

GRADED SEALS FROM TUBING: To achieve a successful hermetic seal of different materials together, the linear coefficient of expansion must be close and/or match to avoid the seals from cracking. Our experience in combining dissimilar materials has enabled us to offer a wide range products suited to most applications.

• GLASS TO GLASS
• GLASS TO METAL
• GLASS TO SAPPHIRE
• GRADED GLASS (QUARTZ TO PYREX)
• CUSTOMIZED GRADED GLASS

GLASS PREFORMS: Glass preforms are used in high volume production where  hermetic sealing is necessary.  Our precise tolerances guarantee the same volume each and every time.  We supply a complete line of glass and ceramic preform for single or multi-hole applications. We also offer low temperature solder glass preforms. These preforms are available for glass-to-glass and glass-to-metal. Our preforms range from .040 inches to several inches in diameter, and can be as thin as .010 inches in both the single and multi-bore specifications. A complete variety of glasses is available, ranging in expansion from 32 x 10^-7 to 100 x 10^-7 in crystallizing glasses, and from 41 x 10^-7 to 105 x 10^-7 in vitreous glasses.
