What are the different types of radiator key?
You need to choose the right radiator key for the job you are doing.
A bleed key is for removing unwanted air from a radiator.
Four-way keys are used for turning some kinds of radiator drain cocks or valves (small, square headed taps) on and off when draining a radiator or the entire system.
Many can also be used on some types of outside tap and gas, water and electricity utility cabinets.
Three-legged keys also turn some kinds of drain valves and taps on and off.
Double-ended radiator keys are for fitting and removing radiator valve tails and square section blanking plugs and bleed plugs.
Hex or Allen key
Allen or hex keys are also used on radiator valve tails and plugs.
Radiator spanner and air release key
A radiator spanner and air release key is for fitting and removing valve tails and bleeding radiators.
Universal radiator keys are usually used on valve tails, blanking plugs and bleed plugs, but may have profiles (shapes) to fit other parts as well.
Combination radiator wrench/key
A combination radiator wrench/key is for fitting and removing valve tails, blanking plugs and bleed plugs.
Stepped ratchet key
A stepped ratchet radiator key is for fitting and removing valve tails.
Radiator tail socket
Radiator tail sockets are a quick way of fitting and removing valve tails.
Radiator valve spanner
A radiator valve spanner helps avoid bending pipework when the manual, thermostatic or lockshield radiator valve is tightened or removed.
No key will do every job
You can save money by buying a key that does several jobs, but none of them will do every job on radiator fittings.
A universal key, like this one, may do jobs on radiator valve tails and plugs, but it might not adjust bleed valves.
If you only want to do one job, say bleed a radiator, and leave more complicated jobs to others, just buy one dedicated key, in this case a bleed key.
See the description of each key to find out what they do.
