Depending on whether you are connecting hoses to barbs or nipples, you will have to carefully match the hose clamps types to the intended application. As you investigate further, you will see that there are two main differences in hose clamps. First, you have screw tightened clamps and then there are tension, or spring clamps. When securing high pressure hoses, you will need to find high pressure hose clamps that can be solidly secured using screw drives or bolts to avoid the risk of leaks.
While you might not need large hose clamps, most components are for hoses that are greater than a half inch in diameter. By choosing the right size clamp, it will allow you to secure it properly, in a way that does not crimp or damage the hose. Generally with stainless hose clamps, they use a perforated steel strap that is made to be tightened with a screw drive. By test fitting the clamp on your hose, you should not have to tighten it as much with a wrench or screw driver. Alternatively, the screw driven clamps can easily be installed after the hose is already attached to the fitting.
When using spring clamps, there are a few variations that can are good for use in tight fitting spaces, especially when significant pressure is not a large concern. The spring clamps are positioned into place by squeezing the two flaps or wire flanges in order to spread the spring loaded clamp apart. The ends of the clamps have been folded or bent out to give you some leverage to pinch the ends apart to go around the hose. Their tensioned, spring shape is works to hold the clamp tight onto the hose, but the pieces will need to be threaded through the clamp jaws before you install it.
If you are using hose clamp in humid, damp or potentially corrosive environments, you may need to consider utilizing the stainless hose clamps. The stainless hose clamps are inherently resistant to both rust and corrosion, which can lower the risk of a loose connection. These can be used in marine and automotive applications, for example, among other settings. Regardless, you will want to try to match the clamp to the situation to minimize the risk of leak or rupture. More on this.
