Teeny weeny red O rings top fill tanks

[snow]

Does anyone know whether I can get hold of any of the teeny weeny red O rings that cover the fill holes in the Kanger top fill sub tanks?  I haven't lost one ..... yet.... in all the years I have been using my subtanks but fear its only a matter of time before I lose one of the piddly things. TBH I'm not really sure losing one would be that big a deal but don't want to lose one and find out that it means my tank turns into leaky the leakiest leaker this side of the Severn bridge! Just for peace of mind I wouldn't mind having a couple of spares tucked away "just in case".

had a look at fasttech and found this but can't really figure out, if the ones you want are included

Ooooo thats brilliant Clivia thank you! - Won't really know if any of them will fit but the smallest size kinda looks promising and at that price it's worth a go - I'm sure the other sizes will come in handy for something ... one day .... maybe..

They look about right - just measured one of mine and 4x1 seems right so I've ordered 20
