This is the attachment hose assembly for the Dyson DC14 upright, Dyson OEM part number 908474-37. It is the stretch hose that runs from the U-bend at the base of the machine up to the wand, and it is the part that carries suction to every tool you clip on. Split hoses are one of the most common DC14 faults, and a hose with a crack anywhere along its length will cost the machine most of its cleaning power at the floor head as well.
Built for
- DC14 owners whose attachments have lost suction while the floor head still seems to work.
- Anyone hearing a whistle or hiss from the hose during use -- the classic sign of a split.
- Repair shops and handypeople servicing older Dyson uprights.
- Households keeping a well-built older machine running rather than replacing it.
How to tell the hose is the problem
Cracks and pinholes in a DC14 hose let air leak in along the way, so the machine pulls air through the split instead of through the tool. Suction loss shows up most obviously on attachments, but a leaking hose robs the floor head too. Owners on repair forums consistently report the same diagnostic sequence: filters clean, bin empty, no visible blockage, still weak -- then stretch the hose out in good light and the split appears. Tape is a common first attempt and a common second failure; the pressure differential works it loose within a few uses.

Fits
Dyson DC14, DC14 All Floors, DC14 Allergy and DC14 Animal. Confirm fitment against your machine's model number before ordering.
Fitting it
Depress the release catch at each end of the hose. The lower end frees from the U-bend at the bottom of the machine and the upper end pulls free of the wand. Experienced repairers give one piece of advice above all others: leave the clip and bracket assembly intact rather than separating them mid-job, because that is where most reassembly trouble starts. Kept together, the assembly snaps back into place cleanly.

Frequently asked questions
How do I know it is the hose and not the motor?
Check the filters and empty the bin first, then look for a blockage. If the machine is still weak with clean filters and a clear airway, stretch the hose out under good light and look for cracks or pinholes -- a leaking hose is far more common on a DC14 than a failed motor.
Can I just tape over the split?
Tape is a short-term patch at best. The pressure differential inside a vacuum hose works adhesive loose within a few uses, and a partial seal still leaks. Replacing the assembly is the fix.
Is this a genuine Dyson part?
Yes -- this is the Dyson OEM assembly, part number 908474-37, supplied complete with cuffs fitted.
Why is my replacement gray when the old hose was yellow?
Dyson now supplies this part in steel gray only. It is the same part; the color change does not affect fit, quality or performance.
Do I need tools to fit it?
No. There is a release catch at each end. Depress the lower catch to free the hose from the U-bend and the upper catch to release it from the wand, then fit the new hose the same way.
