Radiator Bleed Key (Pack of 2) – Brass Clock-Type Keys for Radiator Valves, Air Vents & Towel Rails (UK)

This is the Evoges EVOBRK/2 Radiator Bleed Key (Pack of 2) – Brass Clock-Type Keys for Radiator Valves, Air Vents & Towel Rails (UK) available at SparksDirect.co.uk for the best price.

The Radiator Bleed Key (Pack of 2, Brass, Clock-Type) is a practical hand tool designed to release trapped air from central heating radiators, towel rails, and other heating fixtures that operate with bleed/air vent valves. Over time, air can build up in radiators, reducing heat output and causing cold spots. Using a radiator bleed key allows you to safely and efficiently “bleed” the system, improving circulation and restoring optimum performance without the need for specialist tools or services.

This clock-type radiator key features a classic brass construction, offering durability, corrosion resistance, and good mechanical strength. Supplied as a pack of two, it provides spares for multiple radiators or for keeping one in your toolkit while another remains at the heating system for convenience.

Who Can Use It

The radiator bleed key can be used by anyone comfortable with basic home maintenance — no specialist training is required. However, always turn off the heating and allow radiators to cool before bleeding to avoid scalding. If you are unsure, consult a qualified heating engineer or plumber.

Quick How-To (Safety Tip)

• Turn off the heating and allow radiators to cool slightly.
• Insert the key into the bleed valve (usually at the top corner).
• Turn slowly anti-clockwise until you hear air hiss out.
• Close the valve once water starts to escape.
• Check pressure on your boiler and top up if needed.
• This basic maintenance helps ensure efficient, warm heating and reduces noise from cold air trapped in the system.
