OXI-GLASS HT-202-1 HERMETIC SEALS

OXI-Glass HT-202-1® was developed to reduce labor hours, processing steps and the cost of manufacturing quality kovar seals. Its unique ability to hermetically atttach itself to Kovar without per-odidation sets it apart from conventional sealing glass methods. OXI-Glass HT-202-1® is also available with MAG caps for meniscus control.
