Radiator flow valve cap key tap handle knob

Radiator valve cap

Radiator valves had become a bit tough to turn and the original plastic caps sheared.

This new tap/handle like design provides extra leverage (and is stronger than the original caps).

Can be used and stored both horizontally (like a tap) or vertically (more discrete).

Slot to fit the valve is 8.3mm x 4.8mm.
