Joining this to 100mm rigid plastic ducting
I have to replace my cooker hood extraction. I will need to use rigid plastic for most of it and this aluminium hose from the hood to the plastic. The join between the hose and plastic is going to be fiddly and inaccesable so I want to make a solid join that I can fit and forget. Something better than gaffer tape is needed here, what do you suggest?
Question by Steve, 04-08-2015
Thank you for your question.
You will require a male connector to join the two pieces of ducting together. On the rigid side use duct tape to seal the joint and on the flexible side a quick release worm clip will be required. See below for the code numbers.

Rodent proof flexible ducting?
I am thinking about using thie semi-rigid aluminium hose to replace the plastic hose used for my bathroom ectracor fan. We have occasional problems with mice and they have eaten holes through it. Do you think this could help?
Question by Kath, 21-11-2015
Thank you for your question. I have spoken to the factory and we can not guarantee that the semi rigid hose would be rodent proof. A more robust product I.E. our galvanised spiral ducting maybe a better option. Product code GALSS-100
