These KF-16 to 1/2 inch tube Borosilicate glass adapters are used for sealing to Kovar metal or molybdenum and are commonly used in the following applications: for highly electrically insulation, transmitting tubes, image amplifier tubes, He-Ne-laser, clad tube for optical fibers, ozone generators, electroplated conductors entering glass envelopes, and other electronic parts, such as, vacuum tubes, valves, X-ray tubes and microwave tubes, and some lightbulbs. Kovar is a nickel–cobalt ferrous alloy compositionally, identical to Fernico 1, designed to have substantially the same thermal expansion characteristics as borosilicate glass (~5 × 10−6 /K between 30 and 200 °C, to ~10 × 10−6 /K at 800 °C) in order to allow a tight mechanical joint between the two materials over a range of temperatures.
