- Prevent Damaged Units
- Flexible Yet Sturdy
- Equalizes Pressure
If your insulating glass units are transferred from low to high altitudes, or vice versa, install these CRL Breather Tubes into the spacer frame to equalize pressure. Upon arrival at the installation point, simply snip off the tube below sealant surface. Crimp the end, then seal.
The advantage of the aluminum breather tubes vs. stainless steel capillary tubes is that due to their larger diameter they equilibrate faster.
