Cut in cv boot

[Bobton125]

I have a tiny cut in my cv boot (approx 2mm slit)

It’s only on my Kia daily so doesn’t seem worth it to replace the boot, can anyone recommend a glue or sealant I could use to stop it from leaking grease?

Would any superglue do?

Thanks!

I would expect the problem will be cleaning the edges of the cut well enough for the glue to stick. I don't know whether gluing something like a bike puncture repair patch over the slit might cause trouble on the MOT test.

Literally can’t even see the edges, it’s not even hole, basically a 2mm line

Clean with brake cleaner, than apply a drop of super glue or Tigerseal. Check after a few days, if it's flung any grease out, repeat the process.

Ive found a cotton bud dipped in something to clean , often will fit in the split, then as said tigerseal. Its more flexable than superglue.

Just clean it as best you can then use good quality silicon sealer.

Silicone won't work, use either PU (as in tigerseal or similar) or superglue.

Thanks all, will try tiger seal

neoprene repair glue is what you want. It's used to repair wet suits, which are made of a similar material to cv boots.

As others have said, clean it, maybe inject a bit of cv grease into the hole. then add the neoprene over the hole. Leave to set for a couple of hours.

Probably easier just to replace the gaiter rather than gluing it. Other options include buying a second hand driveshaft from a breakers, but will mean you likely have to do the job twice.

Is it an outer gaiter? I bought an air powered CV gaiter stretching tool which I used in the past to replace the gaiter without removing the driveshaft.

superglue is the stuff for this ...any old generic stuff will do if you can clean it up
