Okay, anyone know what the deal is with the Silca nozzle thing that blows off the valve at about 80psi? This is the one that just presses on, not the one with the nifty little wire lever. Is it just a matter of screwing up the end cap tighter (but then you can't get the nozzle onto the valve anyway) or what? Ended up holding it on with a bit of string yesterday.

cheers,
Anthony
