J Clips

Jubilee Clips and Their Use in Ductwork

As a widely known brand in our niche, Jubilee® clips are a must-have item for installing ductwork. The clips are made in the UK and the company is well-known for its quality products. Jubilee® was established in 1921 and are manufacturing Jubilee® clips to this day.

The Jubilee® clips are duct clips used primarily to connect hoses to connection points. In ductwork, the jubilee clamps are used to connect flexible ducts to ducting accessories. The clips provide a tough grip on the duct, making it almost impossible to disconnect due to air pressure or by accidents, such as tripping over the ductwork while working in the attic. Another method for connecting elements in the ductwork is by using strong adhesive tape. But with time, the glue withers and loses its power so such connection could easily be broken. On the other hand, stainless steel Jubilee clips are highly durable and efficient, so they are a better long-term solution.

The Jubilee clips come in three different types of steels from which you can choose:

  • Mild
  • 304 Stainless
  • 316 Stainless (HNSS)

There are lots of sizes available, making it easy to find suitable Jubilee clips for the size of your duct. The most common steel belt used in ductwork is 0.60mm wide, but the length can differ according to the size of the duct.

The standard Jubilee clip sizes used in ductwork include:

  • 110mm
  • 135mm
  • 180mm
  • 215mm
  • 270mm
  • 325mm
  • 525mm
  • 660mm

Each Jubilee clip comes with a screw housing on it, which is what keeps the steel belt firmly in place. If you ever need a bigger size connector, you can always attach two Jubilee clips, which will double the diameter. You can also purchase a 30-meter roll and a box of screw housings. This way, you can cut custom-sized pieces from the roll and then add screw housings to create your own large Jubilee clips.

The screw housings of Jubilee clips have one more perk. By screwing them down, you tighten the grip of the clip around the hose or duct. This not only provides a strong connection, but it also makes it almost impossible for air to escape through the point of connection. Providing airtight seals by firmly fastening up the Jubilee clips makes the application of different sealants unnecessary.

However, careful installation is needed. Over-tightening the clip could break something, especially if you are using low-quality duct fittings and flex ducts. If you are concerned about tearing the flex ducting, you can always add a piece of gasket tape below the belt to protect the flex duct. Another protection method is to apply a line of silicone sealant on the inner side of the duct before putting it in place. After that, all you need is to fasten it up with a Jubilee clip. Just note that it will make the connection harder to uninstall if the need arises. It’s best to double-check your connections by pulling the loose end of the duct, as well as checking for air leaks once the system is under pressure.

How to Use Jubilee Clamps

Jubilee clamps have many different applications. Some of the uses include to secure hoses to different fittings in automobiles or to create a strong bond between two garden hoses. Whenever zip ties or tapes might not provide a strong enough connection, Jubilee clamps come to the rescue. In DIY projects you often have to come up with a simple solution to secure an item in place. This is the moment when Jubilee clamps shine brightest. All you need for the successful installation of a Jubilee clamp is a screwdriver. The screws’ head design is made to fit different types of screwdriver tips.

Usually, you will have to slide the Jubilee clamp over the connection point to secure it in place. Alternatively, you can turn the screw of the jubilee clamp counterclockwise until it releases both ends of the steel belt. Then wrap the belt over the connection point and slide the loose end back into the screw housing slot. By rotating the screw clockwise, you will tighten the Jubilee clamp in place. You can use this method for ductwork. If you want to secure your existing connections with duct clamps this method will save you a lot of time.

If you are not sure which size of ducting clamps you need for your ductwork, simply give our customer support a call at 01455 616 444. We can determine the correct size after a couple of questions. If you are still unsure, you can always get a roll of strangling band and some screw housings. You can also purchase larger sized ducting clamps for your project. You will need to cut off any excess material after tightening the clamp in place, to prevent it from getting in the way of other elements and to keep the installation nice and clean.
