Hose that flash cuffs fit

[dazzle]

I have flash cuffs but they do not screw all the way onto my vac hose. Does anybody that uses flash cuff know which hose has a smooth bore that flash cuffs fit well?

just squirt some goop in the cuff to hold it in. It's a waste of money if you buy a hose for the cuff
