I've got a leak in the plastic hose. What's the best method to fix that will handle 6 bar?

Also, when I took it off the bike, I noticed that the bottle cap unscrews and fits a 2 litre bottle 😀 Has anyone tried a big bottle and up to what pressure.

could you sleeve the tube with a tight fitting, glued in place, larger sized tube?

The tube is fixed at both ends, so can't be disconnected to slide over a new tube.

Am contemplating splitting a tight fitting tube, plenty of glue and positioning over the hole with the split at the back.

And plenty of cable ties to hold it all together.

Any better ideas?

Can't think of a better fix I'm afraid.

I've been tempted by the air zound for ages. It's very embarrassing testing one in a nice quiet bike shop 😉

Seems to be holding and I just tested a 2ltr bottle up to 3 bar.

Well over a minute of horn time at full volume!!

Should I go to 6 bar?

only with ear defenders!
