No Nonsense External Leak Sealer 50g
No Nonsense External Leak Seal
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.

THIS IS A JOINT SEALER
'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.

Save your Money, Doesn't Work
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!

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.
