  • Create an extra strong and tight duct connection
  • Directly connect Fan + Filter
  • Quick set up, easy to install & Maintain
  • Available in 100mm, 125mm & 150mm
  • Suitable for all brands


Make setting up extract systems super easy, removing the need for cutting down ducting, using rigid fast-clamps or using tape as an ad-hoc sealant.

Depending on the brand, the flanges on your fan and filter may be slightly different sizes, making the use of a fast clamp or metu-clamp impossible as they tighten around the flange at the same time, leaving a leaky, unprofessional connection. The rubber duct connector solves this issue as each side of the coupler tightens along with the jubilee clip, accounting for slight differences and giving a leak-free fitting each and every time.

Offering much more flexibility than directly attaching your fan to your filter, the rubber collar allows for a bit of movement, making installation of your extraction system really easy and simplifying any future maintenance (such as replacing your pre-filter or carbon filter).

An un-assuming and nifty piece of kit that offers a fantastic failsafe for exhaust systems.

With jubilee clips included, the rubber ducting collar is amazing value for money as it’s cheaper than buying ducting and jubilee clips separately and performs much better, with less drop in pressure.

Rubber Duct Couplers are available in the following sizes:

  • 100mm / 4 inch
  • 125mm / 5 inch
  • 150mm / 6 inch

We recommend using Fast Clamps or METU Clamps for larger filters and fans.

How to use:

Quick set up, easy to install

Attach coupling between fan and filter

Tighten the jubilee clips on each side until they grip the flange of your filter and fan

Install fan and filter as one unit, making sure to properly brace the carbon filter to the ceiling of your tent or room
