Different Air Duct Clamp & Everything You Need To Know
One of the most important parts of your heating and cooling system is the duct clamps or ductwork that moves air from the supply unit to where it’s needed in your home or workplace. Keeping this ductwork in good shape with properly sized duct clamps will keep the air moving freely and help to keep your system running smoothly and efficiently.
If you’re unsure how to identify the type of clamp you need, check out this guide on everything you need to know about the different types of duct clamps so you can get your system up and running quickly and easily.
Band Clamps
A band clamp is a type of clamp that consists of a round, V or U structure band with a rubber strip on the inside. This strip is used for sealing ductwork and other pipes. The band clamp is made in several sizes and can be attached with a screwdriver or just by hand. The benefit to this type of clamp is its minimal impact on your ductwork system as it only takes up one inch, which makes it perfect for tight spaces.
They can be used in tight spaces because they have no protruding parts that would cause any damage if they get stuck. This makes them perfect for use in areas with little room. It also has excellent durability, which makes it last longer than some other types, making them worth the extra money spent.
Since they are relatively thin, wire clamps can be used on various types of pipes. In addition to this versatility, they also have rubber pad components on either side, making them easier to use when securing the clamp onto metal pipes. This feature makes them more efficient than other bands because they work better on pipes with sharp edges or curves where other clasps might not stay in place.
They can be used for horizontal and vertical pipes and provide a secure hold to your pipe, making it less likely to come loose during use. Wire clamps are also reusable, making them an economical choice.
Spring Duct Clamps
A spring ducting clamp has a fixed head and a movable, screw-operated collar that tightens and loosens the spring around a pipe. The spring is typically made from stainless steel or copper wire; – it is commonly coiled into a helix shape with an opening at one end.
The stainless steel or copper wire ducting clamp is tightened by turning the knob which compresses or stretches the spring against itself, thus squeezing the pipe between them. Spring clasps are often used in residential HVAC systems because they provide a stronger grip than regular band clamps and can be removed without tools (if needed).
These bands work with very small or thin material by tightening their bolts on either side. They are made up of two metal strips and two bolts with a lock at the end. One set will go around one pipe while another goes around the other pipe then they are tightened down by tightening each bolt separately.
V-Band Clamps
These clamps are either self-locking or non-locking quick fit ducting types and require fasteners like bolts or screws for installation purposes. They can be used on round surfaces and feature a rounded clamping surface, so they don’t damage the secured material. They come in different sizes and can either tighten or loosen by twisting or lifting the collar. It’s important to note that these are among the heaviest type of duct braces due to their size and weight.
Metal Duct Clamp - Another V Band Clamp
Ear Clamps
One of the most common types, ear bands, are typically made from metal. They come in a wide range of sizes, and you can buy them from plumbing supply stores. These galvanized stainless steel duct clamps are easy to use for smaller ducts and will work for many projects that don’t need anything more heavy-duty. This type is often used in residential construction as well. A good example would be at the end of kitchen venting systems when there isn’t enough space for any other kind of clamp.
Remember, there are two types: compression ear bands and screw ear bands. A compression ear clamp is popular for smaller projects because it is faster and easier to use than a screw ear clamp. It consists of a cylindrical shaped head that has small perforations. These perforations allow the tube clamped to move as necessary to make a tight seal. It also has 3 jaws aligned to compress over an opening on one side of the cylinder head and grip tightly on the other side, which results in a secure clamping action.
The screw ear ducting clamp consists of screw thread at one end side and a coil spring at the other. The screw threads can be tightened by rotating them clockwise or anti-clockwise depending on their orientation, resulting in gripping or releasing pressure, respectively.
Wide Coupling Duct Clamps
For larger ducts, you might need a wide coupling duct clamp. These clamps can be used in various applications and are designed for heavy-duty use. Sometimes these clamps are referred to as couplings because they usually have wide band.
A wide duct clamp is an excellent choice for a job that requires a lot of force or pressure, such as joining two pieces of pipe at an angle or welding pipes together. These large duct clamps are also good for connecting small sections of tubing.
Flat Cushion Clamps
These quick fit ducting braces come in many shapes and sizes and can be customized with threaded rods so you can tighten them as much as you want. You can also find these secure fit clasps with plastic sleeve components that make it easier to grip onto your pipe or cable when tightening or loosening.
They’re also ideal for quick fixes on smaller-sized pipes and cables because they don’t have any extra parts that need assembly before use. For example, if a connector breaks, all you need is a Flat Cushion Duct Clamp, which comes with components, such as an attached nut, washer, and bolt.
U-Bolt Clamps
These types can only be used with pipes of a similar size and material but provide an easy way to clamp down tightly on both pipes simultaneously, giving an even pressure all around, which prevents leaks. They work well for flat surfaces, like a metal duct, and are often easier to use when there is little space. Plus, these stainless steel duct fasteners can be tightened with a wrench or pliers, making them more reliable than clasps requiring two hands.
Oval Clamps
An oval duct clamp is designed to tighten around ductwork or any other round, cylindrical object or rolled edge. They work well for securing pipes, hoses (hose clamps), and cables.
The oval fasteners or hose clamps squeeze the inside walls of a hose as you twist it onto your tube. The force on these walls determines how tight the hose clamps grip your tube.
Double Bolt Slim Ring Clamps
Double bolt slim ring clamp ring is a type of clamp that is used to assemble suction pipes for wood chips and sawdust of dust collection industry. This type of clamp is made of galvanised steel or electrogalvanised sheet metal. They are available in a variety of sizes and styles to suit your needs. From 80mm to 850mm in diameters. It’s very popular on the market due to light weight and affordable cost.
Adjustable Bolt Pin Pull Rings
This clamp is typically made from carbon steel or stainless steel and can be bolted onto either side of a duct. The adjustable bolt clasps allow for easy installation and removal of the clamp. Another advantage is that this stainless steel or steel clamp can be adjusted up to wide degree to meet your specific needs.
It’s also easier to work with these clamps than with traditional worm clamps because there is less hassle when it comes to installation and removal. All you have to do is loosen the bolt of the band clamp using a wrench,adjusting the clamping range you want, slide them over your duct pipe or duct bends, tighten them back down again, and voila!
Snap Close Or Ratchet Duct Clamp
The Snap Close or Ratchet duct bands are designed on flat surfaces and are typically used in metal-to-metal applications. This type of clamp is ideal for clamping metal sheets together. The clamp consists of a bolt, two washers, and two nuts that screw onto the bolt.
(When tightening), you’ll want to tighten one nut first and alternate by tightening the other nut opposite it until it’s tight enough. Depending on your needs, the bolts can be placed anywhere along the length, so you’ll want to measure how far apart you want them before installing them. Then simply tighten, and you’re done!
Finally, this clamp style is easy to install, but if installed incorrectly, it can damage both surfaces due to improper alignment or over-tightening.
P Style Clamps
P-style clamps are an alternative type of duct clamp that can be used in conjunction with any other type in your ducting clamps tool station for easy connection. They are also called compression or wide-mouth braces. These fasteners work by pressing two flat surfaces together and squeezing them for a tight seal. The clamp is good for sealing larger ductwork in central heating systems, commercial boilers, and furnaces.
The P-style clamp is designed with a narrower front surface than other types and has a wider rear surface that allows it to compress more tightly on thin sections of pipe. This makes these clasps ideal for sealing larger diameters and stainless steel material or other materials with small holes or gaps between sections, making it difficult to install other types.
