Sealing Ducting

[MortarThePoint]

What, if anything, is needed a ducting connections? For example where a 90 degree bend pushes into the end of a straight pipe.

 

Is any pressure testing required?

Depends on the material. I used a little acrylic sealant on the connections then taped over the join with aluminium tape.

If it the white plastic duct you are thinking about you can use plastic pipe solvent cement also.

It's Manrose PVC ducting, a mixture of 125mm circular and 204x60 rectangular.

 

I'm not wanting it all to be set solid and unmaintainable. Fear of commitment perhaps. Aluminium tape sounds good and I could use Everflex 195 which has been my go to for other sealing jobs. Its datasheet mentions PVCu, so hopefully OK.
