We can design and process various types of glass-stainless steel electric vacuum devices according to customers’ drawings or requirements.

    The shell is made of 304L, 316L and other materials, which are finished by machining. The pins are made of matched iron-nickel alloy materials, and the insulators are made of glass or ceramic. After chemical or electrolytic polishing, the stainless steel shell is passivated, nickel and gold plated on the pins.

    Because of its flexible installation and connection, it can withstand high pressure and temperature, 400℃ under normal pressure, dozens of MPa under normal temperature and its corrosion resistance is better than other materials, so it is widely used.
