Glass to ISO-K Adapters – Precision Sealing Between Glass and Metal

Our Glass to ISO-K adapters are expertly engineered to connect vacuum glassware to ISO-K flange systems with precision and reliability. These adapters are compatible with commonly used glass types such as:

• 7052 glass
• 7740 Pyrex
• Quartz
• Soft glass

To ensure a secure and durable seal, we use high-quality metals including Kovar, Copper, and Stainless Steel 304. For certain glass-metal combinations, a graded seal transition is required — for example, Quartz to Stainless Steel 304 connections typically involve a Pyrex-to-Quartz transition to manage thermal expansion differences.

🔧 Available Configurations:

• Open-End Adapters – Ideal for direct connections
• Domed-End Adapters – Suitable for sealed or closed-end applications
