## Long description

Perfexim metal radiator air vent key 20-402-0001-000 is a compact metal bleed valve key designed to operate standard radiator air vents. The tool enables controlled opening and closing of radiator bleed valves to release trapped air and restore correct circulation in heating systems. Its durable metal construction provides a stable grip and resistance to wear, making it suitable for routine household maintenance as well as professional service tasks.
Advantages
The metal construction ensures long service life and reliable performance when turning small radiator valves. Its compact size allows access to valves in tight spaces behind radiators or beneath radiators mounted close to walls. The key gives precise control for gradual air release, reducing the risk of spills and helping to maintain efficient heating system operation.
Suitable for
 Bleeding air from domestic radiator systems
 Routine maintenance by plumbers and heating engineers
 Use in apartments, houses and small commercial premises
 Accessing compact or recessed radiator valves
Key specifications
 Material: metal construction for durability
 Shape: small hand tool designed to fit standard radiator bleed valves
 Size: compact form factor for access in confined spaces
 Finish: corrosion-resistant surface treatment for extended use
How to use
Place the key onto the radiator bleed valve square or slot, then turn slowly counterclockwise to open the valve until air begins to escape. Once water appears steadily, turn the key clockwise to close the valve securely. Use a cloth or small container to catch any drips and avoid over-opening the valve. Perform bleeding with the heating system cooled or at low pressure if possible and follow any manufacturer guidance for your radiators or central heating system.
Usage recommendations
For safe and effective operation, use the key with appropriate personal protection such as gloves and eye protection when necessary. Inspect the key periodically for deformation or corrosion and replace if damaged. If heating system issues persist after bleeding, consult a qualified heating technician.
