01AUTOMOTIVE REPAIR & SPECIALITY TOOLS
Precision for your central heating system
When a radiator hums or fails to reach full temperature, the culprit is often invisible: air trapped within the metal casing. This small tool addresses that hidden variable directly.
The two-piece set allows you to access bleed valves across different heights and angles, restoring consistent heat flow throughout your home's heating system.
02DESIGN
Dual-key configuration for varied access
The set comprises two distinct keys, allowing you to reach valves in tight corners or high positions without contorting your arm. The 5.2mm dimension is specific to common valve heads, ensuring a snug fit that prevents slipping during rotation.
FUNCTION
Restoring thermal efficiency through bleeding
By turning the bleed valve open, the tool releases compressed air pockets that block water circulation. As the air escapes, water fills the void, allowing the radiator to heat evenly from top to bottom rather than remaining cool at the edges.
