WZ Radiator Bleed Key Valve Clock for Bleeding and Air Vent Made of Solid Brass Pack 2

FITS MOST UK RADIATORS & TOWEL RAILS: Standard square opening fits the bleed valves on most UK radiators and heated towel rails, so you can release trapped air and get cold spots heating properly again. SOLID BRASS - WON'T BEND OR BREAK: Made from solid brass, not thin pressed metal, so it won't snap, bend or round off in a stiff valve. Brass also won't rust, so it's ready to use every winter. EASY-GRIP CLOCK STYLE HANDLE: The wide clock key shape gives you a firm grip and easy turning, even on stiff or awkward valves behind furniture. Comfortable to use for anyone. PACK OF 2 - ONE SPARE: Two radiator bleed keys, so you can keep one in the kitchen drawer and one by the boiler. Ideal for homeowners, renters, landlords and DIY plumbing kits. BLEED RADIATORS & SAVE ENERGY: Bleeding trapped air helps your central heating run efficiently. Hold a cloth under the valve, turn slowly until air hisses out, then close it when water appears. Backed by a 1-year warranty.
