Merriway BH05361 (2 Pcs) Radiator Valve White Push-Fit Cover Caps - Pack of 2 Pieces

Well made fit perfectly great price

I found, as others have done, that the hole in the internal rubber collar was too small to fit over the spigot projecting from the top of the valve on my radiator. This needed to be enlarged, which was not that easy as it is made of hard rubber. It is necessary first to remove this rubber collar from the plastic cap in order to gain full access to the collar. I tried, initially, to enlarge the hole with a small diameter circular section file. This was unsuccessful. I then used a small triangular section file and eventually I managed to enlarge the hole sufficiently. The collar could then be pushed over the spigot and the plastic cap could then be placed on top of the collar. It was then fine. In order for the cap and the collar to stay in place the hole in the collar needs to be only just large enough to ensure a tight fit.

I expected a universal fitting but my valves must be odd!

I live in a 70s house, which over the years has not had the radiators looked after. Due to this, the caps on the rads had mostly broken off leaving a brass pole sticking up.With a toddler this was dangerous, so we bought these and fitted them on all the radiators with exposed brass points. They push on and pull off (needs some force) and cover the fittings well. You can't turn the fittings to isolate the radiator with them, but if you have some pliers you can take them off and use the pliers.

I bought this as I had a missing cap from a radiator. The item arrived as scheduled and appeared fine. However, I removed one of the caps from the package and immediately thought "this isn't going to work". I tried it and it just flopped about. I got the second one and found that this one had the crucial black rubber washer inside. Popped the washer onto the radiator valve and put the cap on. Perfect. As it wasn't a lot of money and I only needed one, I'm not going to bother returning. Beware if you are thinking of buying this.

Radiator valve cover does exactly what it says

I mean, it's a white cap, which if your radiator doesn't have one is rather helpful.The included plastic washer is going to be pretty useless unless your valve is exactly the size it is. What I did, which seems to have worked quite well, is to use some milliput hardening putty squidged into the top of the valve to take a mold of the existing valve (which I covered lightly with tape). Has worked well - won't twist the cap, but means it sits very neatly on and improves the look of the radiator.

Does the job, however to make mine fit properly. (This may be because my radiators are over twenty years old, perhaps if you have more modern ones than you may not have the same issue. )I had to remove some of black rubber inside the cap. By just running a sharp knife against the inside of the top inner ring to increase the size of the hole slightly. It took me seconds to do and the caps now sit as they should.
