Practical key with a square profile for easy bleeding of panel radiators such as R64, R35, and R91. Enables fast and clean air release from the heating system, improves heating efficiency, and prevents unwanted hissing.
The universal square key is an essential accessory for maintaining heating systems in homes and commercial buildings. It is designed primarily for bleeding panel radiators types R64, R35, R91, and other compatible models with a standard square valve.
Easy handling enables efficient removal of air pockets, thereby increasing heat output and reducing the risk of corrosion and noise. Thanks to its compact dimensions, the key can be stored conveniently near the radiator or in a toolbox.
