Hoses do simple work in obvious places, but the way they fail is anything but obvious. A hose can look fine and still be leaking at a fitting, collapsing under vacuum, or cracked on the side you can't see. And once the flow's compromised, everything downstream of that hose gets worse.
This is the genuine Nilfisk Advance OEM 1 HOSE 1/4 ID X 18 IN LONG BLK, part number 7-33-02642, brand new in the box. Hoses are cheap; the trouble they save you when they're fresh is not. If yours is more than a few years old on a heavy-use machine, replace it during your next service — don't wait for it to fail on shift.
Genuine OEM hose has the right burst rating, the right compression rating, and the right connector geometry. Aftermarket hose that's a little off leaks at the clamps.
