Capillary Breather Tubes equalize the pressure between the interior and the exterior of an insulating glass unit.
Pressure differences which normally occur between the sealed air space and the outside environment will be minimized, thus reducing the amount of stress placed on the glass because of severe barometric pressure changes and eliminates the risk of breakage when units are shipped from severe elevation changes.
Capillary Tubes may be inserted into an insulating glass unit at the corner of the spacer which does not contain desiccant. (Desiccant dust may clog the tube, eliminating its effect.)
The representations and recommendations regarding the products are based on tests which we believe to be reliable.
However, no guarantee of their accuracy can be made because of the great range of field conditions and variations
encountered in raw materials, manufacturing equipment and methods. Thus, the products are sold on the condition
that the purchaser will make their own tests to determine the suitability of the products for their particular
purpose. Under no circumstances will McKeegan Equipment & Supply be liable to anyone except for replacement
of the breather tube or refund of the purchase price of the tubes.
