Rated 3 out of 5 by from Didn't really work for me These work as caps for the lockshield but on the wheelhead side they were a problem. They really are quite small and make it difficult to open and close the valve with bare hands. Make sure the valve is turning very freely before fitting. But once they're on they don't come off easily.

Rated 1 out of 5 by from not universal Don't buy this for old Altech valves - the largest hole is much too small; filing the spindle down by the required amount, as they suggest, would fatally compromise its performance. I'm very surprised and disappointed to find Screwfix selling such a poor product.

Rated 3 out of 5 by from better than reviews suggest Bought to tidy up a house-full of radiators with exposed lock shields, these look fine when installed. Reading the reviews prior to purchase helps as the instructions are pretty poor; make sure you fit the retaining ring as other reviewers have pointed out. The adaptor drive disks fitted my spindles fine without any need to fettle, but like any 'generic repair item', you may find the supplied disks do not fit your valve spindle well or at all, its a risk you take. I ignored the instructions for fitting, finding it easier to fully assemble the cap before fitting onto the spindle; aligning the drive disk slot to the spindle was not a problem and I found the caps fitted with just firm hand pressure. They smarten up the radiators nicely and add a bit of protection.

Rated 5 out of 5 by from Nicely Finished Product Item taskes a little effort to push on, but provides a smart, solid finish - works better than the screw-on originals.

Do radiator safety valve caps come in sizes other than 15 mm

Asked by: Bl68
Hi B168, These will fit over the spindle of any of the standard radiator and lock shield valves Screwfix sells. As far as we are aware, these do not come in other sizes. I hope this information is of help to you.
