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

I use these to bleed my radiators, They work well.

Exactly what I needed for my old school cast iron baseboards

Fits in my radiator they're really nice

I tried these on several radiators and had no issues bleeding the air out. They don't feel like solid metal but I was able to apply a fair amount of torque without any breaking/bending/cracking. Not a terrible deal, I paid about $11.50 for this pack of 5 since a lot of Amazon listings for these things are upwards of $10 each. You can find better bleed keys at the hardware store for cheaper but if you want to save yourself a trip to the hardware store with prime shipping these work fine.

As a hospital mechanic I need to occasionally bleed air out of the lines used to heat areas of the hospital. After I bought these, the other mechanics are asking to borrow them.

All good

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.

My batch is great. Sturdily made and fit my radiators. There is not a lot of play for leverage due to the size of the key, but if you don't force it and apply the torque closer to the center, then it won't break.
