Hello,

I just ordred the guitar bridge clamp at Cariko, but I wonder the size of the needed hose.
Is 6mm inner and 8 mm outer correct (1/4" & 5/16")?
Do I need an adapter or is it a bare hose ?

Thanks in advance for help,

Cheers,

Dany

Dany - it's a 1/4" OD bare hose that goes into a quick release fitting.

Thanks Tony, sure it helps.

6,35 mm ( 1/4") will be hard to find here, even on the web, but I'll try with a 6 mm OD and a little piece of tape to make the 1/64" difference.

Have a good day

6mm will work according to a Spanish luthier that has the bridge clamp.
