Rated 5 out of 5 by from convert imperial to metric rad These are ideal if fitting a metric radiator in the place of an existing imperial sized one. They have the older style large nuts which fit older valves, so just turn off both valves crack the nut on one side of the radiator, catch the water that comes out and swap the radiator without draining the system. I had one small leak because the new rad had a sllightly different angle and this stressed the joint.

Rated 5 out of 5 by from Leaky Valves These valves would work fine in a vented (Low pressure system) but there can be problems with an unvented combi system. I had fitted one about a year ago in a combi boiler system and all was fine until recently when the boiler started to over pressure and the tail started to leak. It looks like the seal on the sliding part of these valves is weaker than a conventional joint and the excessive pressure proved to be too much. It's not a fault with the valve but it is a pain when it happens and its worth taking into account when you fit these valves. The solution (as has been said in another review a while ago) is to seal the valve on the inside with a silicon sealer (fernox is a good make) before you fit it and then after you fit the tail leave the rad dry for a hour or so while the silicon goes off. This should give a good joint which will hold pressure. Its a bit more messing around but still nothing like as time consuming as changing the pipework to the radiator.

Rated 5 out of 5 by from Perfect little solution I used these to replace a heated towel rail radiator in my bathroom, we had left the old tails in the old radiator and disposed of it all down the tip. However to my delight and surprise I came across these fitting which meant that the Radiator would fit easily and more to the point perfectly even though it was just a little longer than my old radiator, it fitted because of the telescopic pipe fittings which will go inside the radiator until it fits perfectly,easily and totally watertight. I cannot understand the White & Chrome description though as they are all chrome which pleased me no end, perhaps they come in white also??

Rated 5 out of 5 by from Saves a lot of work I used these tails where the pipes had been fitted for an old imperial size radiator and could not be moved. Very easy to fit and a great neat finish.

The Tail has 2 flared ends so it seems you cannot change the length but reviews say it is easy to modify.
If I cut one end, which one, and will it affect the sealing ?
