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 TUBE ASM DRIP 20, part number 11175A, 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.
