Compressor Seals for Refrigeration / Air Con

Product Description

Glass-to-metal compressor seals are terminals applied to compressors for applications such as refrigerators and air-conditioning and are used by manufacturers worldwide. With the use of special glass materials, our glass-to-metal compressor seals can withstand high pressure and high electrical loads.

Each glass-to-metal compressor seal consists of a metal base, multiple lead-pins and glass tablets. The glass tablet is mainly made from customized soda barium glass, and has high electrical insulation properties. On request, we are able to offer welding services for the terminals on top of their lead-pins. Our glass-to-metal compressor seals can also be designed as free-directional: welding terminals with air and pressure tightness.


We provide glass-to-metal compressors with outstanding properties, including:
  • ability to withstand high pressure
  • special glass with high electrical strength


These hermetic compressor products are used in applications such as refrigerators and air conditioners.
