About Measuring Hose and Tube Clamps
What's the best way to determine the clamp size you'll need? Simply measure the outside diameter of your hose with the fitting installed. Some clamps accommodate a range of sizes, so be sure the size you need falls in the middle of that range.

Extra-Strength Low-Profile Band Clamps for Firm Hose
The end of the band curls back into the buckle—this gives these clamps up to 25% more strength than other low-profile clamps. They are also known as JS-style clamps. Unlike worm-drive clamps and bolt clamps, these have a low profile with no protruding parts. A smooth interior prevents damage to the hose. Clamps are for firm plastic and rubber hose. They require an installation tool (sold separately).
201 stainless steel has good corrosion resistance.
Note: When choosing a clamp, measure the outside diameter of your hose with the fitting installed.
