Is this the correct item to use to convert the Howdens extractor hood "outlet" (approx 5") to standard 4"flexible ducting ( as used on 4' wall fans ? Thanks richard
The 125mm/5" spigot on your cooker hood is likely to be male.
This item is a 125mm Female to 100mm Male (5" F to 4" M) reducer.
The 125mm female socket should fit over the 125mm male spigot of your cooker hood.
The 100mm male spigot will then fit inside the 102mm diameter flexible hose.You can secure the fixing using quick release worm clips or metal hose clips. For permanent fixings, seal joints with silicone sealant, or duct tape.
With kind regards,
i would like to buy some flat ducting for my elica cooker hood but the outlet pipe on the extractor measures 120mm you only seem to list 100mm or 125mm is there some kind of adapter i can get.
Building a pond - need to reducer 95mm to put into the tank and outlet need to be reduce to a 45mm fitting
