Capillary Tubes for Insulating Glass Units
Specialized capillary tubes for pressure equalization in Plateau glass at varying altitudes.




Pressure Equalization
Our capillary breather tubes ensure optimal performance of insulating glass units during altitude changes.
Altitude Adaptation
Install our capillary tubes to safely transport and install windows in high-altitude environments.


Capillary tubes for window glass on the plateau
The application of capillary tube in double glazed units
This is especially important when shipping, as air pressure decreases at higher altitudes. It is also crucial when transporting dual-pane units to high-altitude locations.

Product
Explore our innovative capillary tubes for insulating glass units.




A capillary tube (also known as a “breather tube”) is a narrow tube inserted into the spacer between the two panes of a dual-pane window. Its purpose is to equalize pressure between the inside and outside of the sealed unit.
