Factors to Consider When Buying The Clamps for Radiator Hoses

rubber hose

If your car overheats, you can cause extreme damage to the engine. You might even be stranded on the side of a busy highway. But all of this could have been prevented with the right hose clamp.

To ensure you get everything you need from your hose clamps, we recommend that you take into account the following factors:

Size and Weight:

The size of the wire clamps you need is dependent on the internal diameter (ID) and outside diameter (OD) of your hoses or tubing. You can find these values on your hoses. Make sure you know your radiator hose diameter before purchasing any radiator hose clamps.

Check the clamp’s description to see what range of sizes it can work with. You want to make sure you get one that fits your hoses without too much of a problem. If you err on the side of caution, you should be fine.

The weight of the clamp is important to consider, as well. If you’re working in the garage, then the weight isn’t much of an issue. But if you’re working on the side of a highway or somewhere that is not accessible by your car, then you might want to opt for lighter clamps.

Number of Items:

You’re going to need just one hose clamp to keep your fuel hose in place, but you might want the option of buying a few more. Some clamps come with a number of items, such as six small clamps, two medium-sized clamps, and a few large ones. If you need to replace or fix several hoses at once, then going for the multi-pack is a good idea.


Most wire clamps are made out of stainless steel, which is great for resisting corrosion and rust. Look for the words “stainless steel” to know you’re getting an appropriate clamp. However, some brands make copper or plastic clamps.

These materials might be lighter, which can be beneficial if you’re working on the side of a highway. Just bear in mind that plastic isn’t as resilient as metal, so it’s not ideal for clamps that see heavy use. As for copper, it might corrode over time, but that doesn’t mean stainless steel is automatically better.


hose fittings

You can choose between three types of hose clamps: worm gear, spring clamps, and racing clamps.

Worm clamps require a screwdriver to tighten them up. They’re not easy to use, but they’re incredibly durable and strong.

Spring clamps are the simplest option. If you use the best spring clamps, you’ll get a tight seal with no hassle.

Racing clamps are a good choice for racing due to their tight clamping pressure. They have reverse screw heads that you can use to tighten them up when it’s time to go. And they’re much lighter than worm gear or spring clamps.


The best hose clamp is designed to prevent a leaking cooling system so no air can escape. Leakage is what causes your car to overheat, so you want to avoid any wire clamps that will allow air through.


With stainless steel being a common material for radiator hose clamps, it’s easy to assume they’re all resistant to rust. But some brands make their spring clamps out of other materials, such as copper or plastic.

If your hose clamp doesn’t say whether it’s rust-resistant or not, you can assume it isn’t if it’s made from a material other than stainless steel. In that case, put a coat of paint on the screw type hose clamps before using them to keep them safe.

Salt Resistant:

small hoses

If you live in a place that’s constantly snowy or near the beach, then salt might be an issue for your radiator hose clamps. They can corrode when exposed to salt water or road salt, so you’ll want a clamp that’s resistant to corrosion of all kinds.


If you plan on working on your car frequently or replacing your radiator hose more than once in the near future, then buying screw type hose clamps might be worth it.

For example, you can get a screw clamp. These screw clamps have a reverse screw head that allows you to secure them with a single turn of the screwdriver. And they’re faster to use than most other types of clamps.

Handy extras might include reusable handles or rubberized grips so you can easily tighten up the clamp without too much effort. And some band style clamps might come with extra features, such as adjustable necks to secure hoses of different sizes.

Versatile Use:

You might think that all radiator spring clamps are used for the same thing and serve the same purpose. But some clamps are designed with specific uses in mind. There are even some that are used to hold together two wires or two cords.

Some clamps might only work with certain types of hoses, such as rubber ones. So be sure to check what types of hoses you can use your clamp on before buying it.


It’s always best to go with a brand that’s known for creating quality products. Since radiator hose clamps see regular use, it makes sense to buy one that comes from a reputable company.

You’ll need to do some research into which brands have the best reviews or are most trustworthy before making your purchase. This way, you’re far less likely to be disappointed with your screw clamps.


You might not think it’s necessary to go for the cheapest clamp on the market. But bear in mind that the best radiator hose clamps are usually more expensive than others.

If you can afford a better radiator hose clamp, then it’s better to spend some extra money on a higher-quality brand. It will look and function better than cheaper options.

How to Tighten Radiator Hose Clamp?

After buying the right set of radiator hose clamps, you need to learn how to tighten them. Simply follow this step-by-step guide:

Step 01. Slide the clamp over the radiator hose and make sure it fits snuggly without falling off.

Step 02. Add one turn on the screw and check if it is secure enough.

Step 03. If it is, then tighten the screw even more for a better hold. If the clamp starts to move, undo the screw and try tightening one notch at a time until you have just enough force to keep the hose in place without slipping off.

So, now that you know how to replace radiator hose clamps with ease, it’s time to get down to business. But, don’t rush it. Remember, this might be your car’s life you’re playing around with.

Frequently Asked Questions

01. How to Remove a Constant Tension Hose Clamp?

Removing this stainless steel hose clamp is not difficult. Start by removing the hose. Next, get rid of the washer and spring from inside the clamp body. Once that’s done, insert a screwdriver in the hole on the top of the hose clamp and turn it. When you feel resistance, pull out the clamp entirely and remove any remaining pieces.

02. How Does a Hose Clamp Work?

prevent leaks

A stainless steel or silicone hose clamp is an adjustable piece of circular metal that tightens around an object to keep it from moving or leaking fluids. A standard hose clamp is composed of two pieces of metal, which are attached to one another in a circle.

These clamps work by clamping onto the outside diameter of the hose and using a spring or screw to keep tension on the hose. The center space inside the circles allows for objects to pass through, while the loops at the top and bottom allow for tightening around it. It ensures a tight seal and prevents leaks.

03. What Size Hose Clamp for 5/8″ Heater Hose?

A 5/8″ clamp is usually used for heater hoses. The more common clamps that will work are 16mm. The inner and outer diameter of the clamp needs to be 0.63 and 0.93 inches, respectively.

04. Can You Clamp a Radiator Hose?

Yes, you can clamp a radiator hose with the right tool. Many cars and trucks today require the use of screw clamps to maintain a tight seal between hoses and other objects.

05. What Size Hose Clamp do I Need?

The size of the clamp needed will be determined by where it’s going and what you’re trying to accomplish. The length of the hose, as well as the diameter, will determine which size clamp you need.

The size of the hose clamp depends on the internal diameter of the hose or tube being clamped, not its external diameter. Clamp size is specified by two numbers separated by a dash which correspond to the internal and external diameters respectively in millimeters. For example, a tubing with an outside diameter of 6mm and an inside diameter of 3mm will require a hose clamp specified as 6-3.


Radiator hose clamps are a very important part of the cooling system. When tightened properly, they help ensure that you will not lose coolant from a hose failure and prevent overheating of the engine’s coolant.

Cooling systems typically operate at temperatures below boiling point, but even this low temperature is hot enough to cause serious burns if exposed to exposed skin for more than a short time.

If coolant is lost and does not get replaced, the engine will overheat and be destroyed in a matter of minutes. Take care with the tightness of the best clamps for radiator hoses, or you may have to pay an expensive repair bill later on.
