I think this would be a great product for air con pipework etc.Unfortunately, I was trying, as an experiment, to use it for something for which it was not designed, and it didn't work.This is NOT to detract from the product in any way, seems well made, relatively easy to cut to get the sections that you want etc, so I think it would be a quick and easy way to expand or contract air conditioning (etc) plastic pipework.Very fast delivery, very well packed.

Does what I need it to do. A bit on the expensive side for what it is, but hey..It works!

Product as described. I was expecting to have to, somehow, cut off the unwanted sections of larger & smaller diameters to ensure a good fit. Good job I tried it first as it was slightly larger at one end and the smaller diameter was perfect for the flexi duct.

I bought this to see if it might be adapted to a problem as the dryer hose and flexible hose wouldn't fit I needed to adapt a connector as a repair. Sadly the hose pipe is a very odd size that this item couldn't work. No fault with the item just not right for what we needed to do.

Easy to cut to size using side cutters, fits OK.

As described, this allows conversion of differing sized pipes, easy to cut (saw) to get to the correct width if necessary.Item arrived before scheduled date and in good condition.
