Good product and good value for money. Opted for this one as it was slightly longer so could secure ducting onto it nicely. Works well.

It does what it says on the tin. Good construction and fits as described.

Had to join 110mm hose to 100 mm found this part worked perfect

Verarbeitung ist in Ordnung, gute Passform und hat wunderbar als Verlängerung für meinem Kondensatablauf gepasst

Used these to join 100mm flexi pipe to a 110mm roof vent, just the job! For those who complain about them, research how to do the job properly before you start, this product is good!
