150-100mm duct reducers?

[GGP]

Hey does anyone know where I can find a 150mm to 100mm duct reducer in Perth? I want a clean connection so I won't just cut up the 150mm ducting and reduce the end with tape. Needs to be a proper, good quality duct reducer. Everywhere I've been to only has 200mm to 150mm and up.

If you are battling, try airconditioning places or maybe plumbing stores which sell stormwater/agriculture pipe. If you can't find one you can make em pretty easily. I have made two of my own, one using a really thin Aluminiumy type sheet of gear and gaffer tape(that can be cut with scissors) and one with sturdy cardboard. They both work just like a bought one and don't leak at all if you use enough tape. Just fold whatever you want to use into a cone-like shape to fit either ends of the ducting and tape it up.

Hey GGP, I'm a perthite too, and getting some items here can really be a bitch eh?

 

Skankmasters advice is pretty good, but you should be able to find something designed for that at a good hydro shop, neh? Ring round, the smaller ones may surprise ya.

 

Oh yeah, and why are you needing to reduce the size of the ducting, if I can be a nosey bastard.... may be you don't need to... course, you probably do, which is why you're posting this in the first place.... but you never know.

I've had the same problem - it's to get my 150 mm exhaust to go to a 100

mm pipe to vent outside. I just cut a short slit in the 150mm lengthways from the open end and curled it in on itself, a bit like when you make a cone out of paper. Wound it in till it was tight on the 100mm and taped it up.

try a 140mm standard nursery pot, ducting adapters are a scam.
