S/SThumb Screw Clamp w/ - 1/2" (8-12 mm) - Blue

Functions the same as a standard Hose Clamp, however rather than needing to find a screwdriver (or dime!) for every adjustment you can easily tighten by hand.

As an added bonus, this also has a significantly smoother inside to the clamp, which will not tear up your tubing nearly as much as a standard hose clamp! Ideal for situations where you need to remove tubing from fittings to sanitize.
Please note, as the reviews will also tell you, this is a clamp that will fit 1/2" OD tubing.
