2. One-time welding of the Flange integrated with groove and the chamber body,with welding deformation <0.2mm.

           3. Easy for Window disassembly & reassembly; Convenient for operation and maintenance. End users are able to take care of Window disassembly

           themselveswithout needs from professionals.   

           4. The Flange type O-ring is embedded in the sealing groove, a way of vacuum air-tight seal, without breakpoints and seams, with strong corrosion

           resistance and good sealing performance, which improves the overall glove box leakagerate to ＜0.0006vol%.

           5. Applicable for the sealing of vacuum equipment View Window and Sealing Door.

           2. Sealing method: The hollow O-Ring is placed between the glass and supporting surface.

           3. Hollow O-Ring: By the compression deformation of the hollow O-Ring, the unevenness of the support surface gets Compensated. The hollow diameter

           is around 2~4mm, some poor-quality O-ring is up to 10mm. And there are wrinkles after the O-Ring is pressed which leads to a high leakage rate and

           unreliable sealing.

           4. A kind of Simple mechanical sealing, not a Vacuum sealing.

           5. Applicable for sealing of Large thin-walled parts whose sealing surface cannot bemachined, or for simple sealing of non- vacuum equipment without

           quality requirements.
