Suitable for all radiators Universally compatible with all standard radiators that use standard valves with the dimensions 5 x 5 mm.
Optimised heating performance without interference noise Our ventilation key for heaters effectively eliminates annoying noise and significantly increases heating performance. This not only saves energy costs, but also enjoy a trouble-free heat source.
Improved feel and functionality thanks to high-quality materials and new design made of first-class stainless steel, our key is characterised by exceptional robustness and durability, unlike plastic or inferior metal casting. In addition, it has a completely new, extended handle that allows even the bleeding of hard-to-reach radiators effortlessly.
Easy to use Once they feel cool, locate the vent valve at the top of the radiator. Insert the bleed key into the valve and turn it counterclockwise to release trapped air. The characteristic hiss signals the air deflation. When the hissing is silent and water leaks, the ventilation is complete. Finally, tighten the valve using the bleed key.
