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.

Tight-Seal High-Torque Bolt Clamps for Firm Hose
Clamps offer extra holding power in high-torque applications.
The bolt design provides good strength and creates a 360° seal to prevent leaks. Clamps have fair corrosion resistance. They are for firm plastic and rubber hose. They are not recommended for use with helix wire hose and hydraulic hose. Do not exceed the maximum torque or clamps may be damaged.
Double Bolt—The tightening force is equally distributed between both sides of the clamp. These clamps open completely for easy installation and have reinforced bolt lugs to prevent the clamp from bending out of alignment.
Double Bolt with Saddles—Same as the double-bolt clamps, except these have two saddles to maintain even pressure around large-diameter hose.
Note: When choosing a clamp, measure the outside diameter of your hose with the fitting installed.

Vibration-Resistant Worm-Drive Clamps for Firm Hose and Tube
Unlike vibration-resistant pinch clamps, these have a torque rating for extra holding power in high-vibration applications. They are also known as high-torque clamps.
Clamps are for firm plastic and rubber hose and tube. Do not exceed the maximum torque or clamps may be damaged.
410 stainless steel has good corrosion resistance.
304 stainless steel has very good corrosion resistance.
316 stainless steel has excellent corrosion resistance.
Note: When choosing a clamp, measure the outside diameter of your hose or tube with the fitting installed.
