does this product fit directly to a 150 to 125 adapter, or does it require additional fitments ???
Thank you for your question. You will require a male connector to join the 150mm end of the reducer to the pipe. The product code for the connector is QS284. Also quick release worm clips will be required to connect to the pipe and the connector and reducer the product code for these items are QS1376,QS1377. If I can help any further please do not hesitate to contact me.

Is the 127mm diameter the inside or outside of the pipe.
Hi I have a Neff cooker extractor fan with an outlet of 150mm. They also have included a reducer which fits the spigot of the outlet. I would like to use this. The outside diameter of the reducer is from 150mm to 118 mm would this product be suitable? I`m at a loss of how to connect some venting to this adaptor. Your answer would be appreciated asap
Can you make quite tight bends in it i.e. round a 90-degree corner, or does it need to be curved more gradually (resulting in bigger boxing-in)
Will the plastic 125mm duct retaining clip fit the semi-rigid aluminium hose, which has a slightly greater diameter (127mm), or is an alternative clip for this ducting available?
What is the internal diameter of this pipe when compressed. The largest it can be? I see previously stated the internal is 125mm, but i assume this is at full extension. I require it to fit over a pipe measuring 128.2mm
I'm using 125mm plastic 90 degree bend. Would 127mm or 125mm flexible hose be best?
Both ducts will have an internal diameter of 125mm, so either of them would fit the bend. They are just measured differently by their manufacturers. One measures I/D and the other measures O/D
