HI - I'm installing a cooker hood and intend to use this product to vent externally. I need around 4 meters of it so will have to join 2 pieces together. The pipework will be visible in the room so I hope to have as neat a join as possible. How should this be joined - with male/female connector and clip..... or otherwise? Thanks!
My suggestion would be to use a 'safe' male connector (GALNPU-150) - This will fit inside the semi-rigid hose and will form a tight seal without the need for any clips, tape, or any other effort on your part - and the connector will be almost invisible as the hoses will go over each end. The semi-rigid can be cut to the appropriate size and different lengths can be joined together using the connector.
With kind regards,
Hi I need to duct out a wall mounted cooker hood with 150mm ducting which will run 3m through a pre-existing box which has a steel in it which is fixed into the outside wall. Because of access issues and the fact that the run won't be dead straight, would it be possible to fit rigid plastic from the outside wall and then join it to this semi rigid aluminium on the inside and then join semi rigid onto top of cooker hood, or onto 90 degree rigid plastic bend to get to cooker hood? What would I need to order to do this? Thanks
Would it compress (squash without damage) to squeeze through a 100 ml gap in the roof truss
Q1-What is the external diameter? I have a 152mm Diamond Core Drill bit, so need the hose to fit a hole that size. Q2-I need the hose to vent from a kitchen extractor fan out thru the kitchen wall. Can this hose be bent into a right angle, and will it keep that shape with use?
I want to replace the existing polythene 150mm ducting from my cooker hood. It goes through the ceiling, the eaves in the attic and connects to 100mm plastic pipe that connects to a chimney vent. 3m hose will suffice. What else do I need? Thanks
Hi, my installation is in a difficult, almost inaccessible, part of the roof. To link the roof inlet to my cooker hood, I figure I will have to use "trial and error" to get the final run of the duct. Is it O.K. to fully extend it (from 0.8m to 3m, then bend it into shape and re-compress? In essence, my question is "how many times can I bend it without splitting the aluminium"? Thanks Roger Clark
Hi Roger. When using a Flexible duct for ventilation, it is always good practice to keep it as tort asThe answer to your last question is unknown, but bending it several times is likely to weaken the structure of the material.
What is the internal diameter? Does it change as the hose is extended?
