Wal-Rich Radiator Bleeding Air Valve Key Chrome Plated Lot of 5

They werent casted out of pot metal

The bleeding value worked great!

happy with my purchase

The build it poor since if you use this on a one of the tight bolt, this will just get rounded out. Also, since the head is very tiny of this, your fingers will start to hurt after just few times of use. But the result after using this does help heating since it lets all the air out and the heater will be able to heat the entire heater.

They broke within the first turn. Then on the 2nd one. Cheap. Mayne if radiator isnt tight but who knows.

One reviewer complained that these keys broke. Yes they will. If the valve has been overtightened and is stuck, would you rather break the key or the valve? Thats a rhetorical question....youre better off breaking the key.

My radiators are older and unfortunately these were too big in size.

These split right away. Extremely cheap soft metal.

If you apply any kind of torque to these, the metal will snap off. The fitting of the key goes extremely close up to the edge which is where the metal split just from turning with my hand.

Worked well for bleeding my old hot water radiators. Seem to be a good quality product.
