Closed Dome End 7740 Pryrex^® To Stainless Steel Metal Adapters

Domed, single flange glass adapters are constructed with 7740 Pyrex^® glass and stainless steel metal transitions. These closed adapters are ideally suited for high and ultrahigh vacuum applications where an optically clear chamber is required is required. Available in various glass tube diameters.

Features:
• 7740 Pyrex^®.
• Sttainless steels leeve.
• 304 stainless steel flanges as standard.
• Custom sizes and configurations available upon request.

PLEASE NOTE :
1 – Although a highly specialized technology, glass-to-metal sealing and fabrication is more of an art than a science. As such, glass dimensions are nominal and only provided for reference. Note that glass lengths, diameters, and/or wall thicknesses can vary significantly from part to part. For example, glass adapter lengths can vary by as much as +/- 3.3mm

2 – Glass-to-metal interface diameter is smaller than that of metal or glass tube IDs. Objects inserted through this region must not exceed “D” diameter.
