2pcs Zinc Alloy Radiator Exhaust Valve Key 5×5mm Square Socket Radiator Accessory Heater Exhaust Key for Standard Heating Valves

2pcs Zinc alloy radiator valve keys. They are vent radiator maintenance and air release accessories. They are suitable for heating ventilation valves and serve as small wrenches for manual air release valves.
Tips：Because the exhaust valve key is small and easy to lose, it is recommended to buy a few more spares
Features:
*Clean the radiator: Older radiators tend to make unpleasant noises. Regular bleeding using the heating ventilation key protects your hearing and improves heating performance.
*For all standard heating valves: The heater exhaust key has a square socket of 5 mm. With this, you can quickly and easily drain almost any heater.
*Shatterproof material: Thanks to the special zinc alloy, the radiator ventilation key is the long, faithful companion of the toolbox. Our silver heater ventilation keys are anodized to make them corrosion resistant and extremely durable.
*It can also be used in closed conditions: this is not a problem if your heatsink is not well installed. Our heating keys are small and compact. This allows you to ventilate comfortably at any of the smallest angles.
*Easy to use: Simply place the sturdy exhaust key on the valve, gently rotate it and flip it over. (When venting the radiator, please pay more attention to safety and be careful of burns,)
