Old vent hose knackered, bought a new one. So far, so good.
On the back of the dryer there's a plastic outlet port, 100mm diameter, with an internally threaded connector of about 2 turns. Its quite clearly a left-hand thread. The hose, however, has a steel coil running through it with a right-hand thread to it. So won't just screw in. They just dont seem compatible with each other. Its the same at both ends too, just to mess with my head. What am I doing wrong here? Can you get hoses with left or right thread?
Yes, I've even thought about turning the hose inside out, but that's a silly idea and defo ain't gonna work.
(I do vaguely remember having the same problem a few years ago when I last attempted this exercise, and ended up just boshing it in and hoping for the best. I'd rather do a better job this time)
Help please, oh clever Trevors...
Just stuff it in and add lots of tape. Job jobbed.
Is it a duct? Use duct tape. If you only have duck tape you’re ducked🤷♂️
I just squeeze them in. It feels like they should thread but I'm pretty sure they don't

Must be what duct tape is intended for, I agree. It still feels like a bodge though
Usually there’s a spigot that attaches to the dryer by thread or bayonet and then the hose goes on the outside secured with a jubilee clip. Make sure that there aren’t too many crevices where fluff can build up as even with the best filters some does escape.

Maybe there was, once upon a time, but I've searched the 'Kitchen drawer of miscellania' and it's long gone, if it ever existed.
There's certainly a female thread on the inside of the vent pipe, along with a small bayonet, as per picture below. Whether those are for securing the flexible hose, or to fix another (now missing) part of the machine, isn't clear.
Ah well, thanks all. I guess it's just going to be a case of 'stuff some in and duct tape' then hope for the best again.
That smells an awful lot like you need Official Hose™ costing six times the price rather than a generic part.
How was the old one connected?
Not sure if I'm understanding this properly but what if you take out that threaded collar and then put the hose through from the other side will the threads match up?
Indesit tumble dryer by chance?
If so they have a reverse thread. Bloody annoying.
@Cougar - no idea about the original one now, bought it prob 15 years ago, and it was then re-fitted in situ for us by the builder when we had the garage converted to utility 11 years ago. More recently, maybe 5/6 years back, I replaced the vent hose, but had the same dilemma I'm in now.
@avdave2 Nice idea, but it'd be a right bugger to remove that - it's got 4 or 5 clips holding it into the steel frame, which would be hard to access and clearly aren't intended to be got at. The thread is only 2 turns deep anyway, doesn't go right the way through the collar.
@jeffl - nah, Zanussi!
Anyway, as of 30 mins ago, it's now unceremoniously stuffed and duct taped in and theres a load of washing being done which will test it shortly. We shall see; I'll check how the tape has withstood the heat after it's completed the drying.

Aluminium duct tape?, it’s designed for such things
Not alu duct tape, no. Just the bog standard silvery cloth stuff at the moment. It seems to have survived drying the first load of washing today at least. Perhaps I need a trip to Screwfix to see what they've got.
Jubilee clips etc wouldn't work unfortunately - the vent pipe goes inside that plastic collar, it's not big enough to fit outside it. The zip ties that came with it have ended up in the toolbox spares.
I'm guessing that the reason for the LH thread in the machine is that there's some kind of adapter collar that you put between hose and machine, and as you turn it anticlockwise to screw into the LH thread in front of it, the other side, because it's facing the other way, is pulling in the RH thread of the duct wire. So you don't have to rotate the duct (as that would be annoying if the other end was already fixed to the outlet in the wall). Google suggests that adapters exist but I can't see the LH thread on any, might just be the photos.
I think that just to make life complicated the ducting comes in two different diameters hence my suggestion for a spigot. Shoving it inside could cause creases and voids where the fluff can build up. May I suggest that you check it regularly for restrictions?

Ah ok, it’ll work fine but keep an eye on the connection between tape/outlet as the heat from the dryer may cause the tape to swell/stretch and become unstuck.
Think I saw some rolls of aluminum tape in Lidl yesterday for about £1.50

I don't think you understand how threads work

No, I was thinking in my mind it makes no difference which way round a nut faces but maybe there is something odd about the collar that would allow for it to fit the other way as it seemed illogical to have a reverse thread.
Not sure if it's just the way the light is falling on that image, but it doesn't look like a left-hand thread to me, it looks standard RHT
Yeah, sorry, you're right now I think about it again, the collar there is right-threaded. But by contrast the vent hose thing is effectively left-threaded, so whatever way they are, they're not compatible with each other. Hence the end result has been 'cram a couple of inches of hose inside, and bosh some tape on it'.
Seems to have done the job so far, and theres noticeably less whiff of damp warm air in the room than there was last week from the old, possibly split, hose. Result, I think.
