No Nonsense External Leak Seal
2 Mar 2015
By onthelist
, London
" Great buy, almost half the price of other branded products. It worked really well when dealing with a radiator header tank. It was no where near as smelly as other brands and when working in a closed in roof space with no ventilation this proved a real bonus. It was also easier to apply and tool than other products. Will definitely buy and use again. Have give 3 start for reliability as I have only just put it on, otherwise a 5 star product. "

" I use this instead of/as well as PTFE tape and it does the job well. It is 60% of the price of the brand name product, but 100% the same. "

Forget the PTFE!
28 Jun 2013
By StevieB63
, Halifax, West Yorks
" I've been using the more expensive Fernox LS-X version of this product for a while now with excellent results and decided to buy a tube of the cheaper stuff to see if it was any different. I can confidently say that there isn't any difference apart from the price - a lot cheaper! Same performance, no problems apart from the tube drying up if you leave the top off for a while, same as the expensive stuff. "

No Nonsense External Leak Seal
23 May 2012
By SteelBlue117
, Bromley
" Works well and better value then other brands.
Only criticism is the cap, which is not really man enough for the job - has a tendency to split and allow the sealant to go off in the tube.

THIS IS A JOINT SEALER
24 Jan 2015
By jonc
, Cheshire
" 'External leak sealer' is misleading. This is a joint sealer, for compression or threaded fittings. I can see I would use this if I had a compression fitting which was weeping and I couldn't get it any tighter. In fact, the best name for this would be 'Small Tube of Clear Silicone Sealant' which is basically what it is.
I bought this for a temporary fix on a pin-hole radiator leak which it was totally unsuitable for. Isn't that an 'external leak'? I actually needed some Araldite. "

No Good Leak sealant
21 Nov 2014
By colliedug
, Motherwell
" No Nonsense External Leak Sealer did not seal the leak from the radiator valve connection. It did not adhere to a wet surface as claimed and was no better than ordinary silicone sealant, a large tube of which is much cheaper.
Managed to seal leak using self amalgamating tape.

Save your Money, Doesn't Work
19 Jan 2015
By Anonymous
, Chorley
" I bought this for a tiny leak on a radiator valve. The product looks and smells exactly like ordinary clear silicone sealant. The leak was from the 12mm micro-bore joint into the valve. I tried several attempts but it just kept leaking, only a tiny drop every five minutes but the sealant couldn't stop it. Looks like a full drain down and new valve/pipe is the only solution. Don't waste your money! "
