As far as I know, hose clamps have almost been completely phased out, especially in the automotive industry.
Hose clamps have basically one pressure point, they don't "slip" around pipe due to the thread cuts in the band part, on plastic male fittings with the hose over them they will crush or split the plastic. On pneumatic or hydraulic fittings, they'll loosen and leak.
I've changed over to crimpable bands, the ones commonly used in automotive and poly pipe situations. Kits with various sizes are available at Amazon and other sites.
