Dust Extraction Hose

[Munroast]

We are finding quite a lot of our 100mm flexible ducting is starting to split where it bends, the stuff is bloody expensive, anyone know of any good quality hose that lasts ?

Have found cling-film, is a good fix, but we are going to need to buy more of the stuff and would like it to last more than a couple of years,

(and there is no sunlight in the workshop, so that is not the problem.

Does it have to be flexible ? Rigid 100mm plastic drain pipe may be the solution, It has a smooth internal surface which means it has a higher flow rate than corrugated flexible ducting.

I use drain type pipe where I can, and the flow rate through that is nearly lossless through that, but flexible is also necissary wher the ducting goes into machines, and some machines like the planer/thicknesser are a pain in having to move and reattach the hose between operations.

It sounds as though you need a heavier dust hose. What are you using at the moment? A lot of DIY hoses are PVC and simply won't stand up to intensive use. Trade shops generally go for polyurethane with copper-coated wire re-inforcing, the smaller the pitch of the re-inforcing the smoother the internal bore and the longer the hose life. Try Ductstore for your needs and look at something like their PU hose. A word of warning - this stuff doesn't come cheap and I've always hated paying for it!

Is the stuff being sanded abrasive? I ask because I worked for a mate with a Festool 125 rotex. I asked him why the external dust port fitting had two slots in it. He replied that the slots were the result of sanding back nail heads.
