A machine that's supposed to move air and water is only as good as its seals. Gaskets keep the vacuum path airtight, seals keep the fluid path leak-tight, and O-rings do both jobs in a hundred small connections. When any one of them gives up, performance drops without any warning light or error code — just a machine that's not quite doing its job.
This is the genuine Nilfisk Advance OEM INJECTOR NOZZLE W/O-RING, part number 6180916, brand new in the box. Replace gaskets any time you disassemble around them. They're the definition of "while you're in there" work — cheap now, expensive to redo.
