Double Ended 7740 Pyrex^® to Stainless Steel Metal Adapters

Dual flange glass adapters are constructed with 7740 Pyrex^® glass and stainless steel metal transitions. These flanged adapters are ideally suited for high and ultrahigh vacuum applications where where electrical break and/or isolation between components is required. Available in various glass tube diameters.

Features:
• 7740 Pyrex^®.
• Stainless steel sleeve.
• 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.
