Tornado Nozzle Hose Adapter Tube 19197

The adapter tube is the transition between the vacuum nozzle and the recovery hose. Everything the machine picks up passes through it, and because it is a change of section it is the place where a blockage forms first. Part number 19197 is the genuine OEM nozzle hose adapter tube for the MWH-800, Marathon 800 and Marathon 1200 machines.

Compatible Models for the Nozzle Hose Adapter Tube

This part fits the following Tornado machines:

• Tornado 98164 MWH-800 8-Gallon Self-Contained Carpet Extractor
• Tornado 98166 20″ Marathon 800 Carpet Extractor (8 Gallon, 115V)
• Tornado 98167 20″ Marathon 800 Carpet Extractor (8 Gallon, 230V)
• Tornado 98168 12 Gallon Self Contained Carpet Extractor
• Tornado 98168 20″ Marathon 1200 Carpet Extractor (12 Gallon, 115V) — all series
• Tornado 98169 20″ Marathon 1200 Carpet Extractor (12 Gallon, 115V)

Start by ruling out a blockage rather than a fault. Disconnect both ends, hold the tube up and look through it. Carpet fibre, hair and the corner of a plastic bag lodge exactly here and build a plug that partially clears each time the machine runs, which is why the fault comes and goes. If you cannot see daylight end to end, the tube is not broken, it is blocked.

When it has genuinely failed, the usual cause is a crack at the cuff where the hose clamps on. That is the point that gets worked every time the machine is moved, and a crack there bleeds air into the vacuum path. The result is suction that has dropped across the whole machine with no water leaking anywhere — which is why people chase this fault through the tank lid gasket and the filter first.

Test for the air leak directly. With the machine running, run a hand around the tube and its joints and feel for draw. It is easier to find than to see, because a hairline crack under a clamp is invisible until the clamp comes off.

Wear is the third mode. Grit passing through at speed abrades the inside of the tube, and a wall thinned enough will eventually split. If you have a machine that works in sandy or industrial environments, this is a part to inspect rather than wait for.

Fit the replacement with the machine unplugged. Note the orientation before the old one comes off — fitted the wrong way round the tube still connects but the internal section steps the wrong way and collects debris far faster. Seat both cuffs fully, land the clamps on the cuff rather than on bare hose, and check for draw at the joints with the machine running before it goes back to work.

Frequently Asked Questions

What Tornado machines does the nozzle hose adapter tube 19197 fit?

It is used on the Tornado 98164 MWH-800 8-gallon self-contained extractor, the 98166 and 98167 20″ Marathon 800, the 98168 12 Gallon Self Contained extractor, the 98168 20″ Marathon 1200 in all series and the 98169 20″ Marathon 1200. Call 763-535-0770 if your machine is not on that list.

My suction is intermittent — is the adapter tube the cause?

Check for a blockage first. Disconnect both ends and look through the tube: fibre, hair and plastic lodge at this change of section and build a plug that partially clears each run, which is exactly what makes the fault come and go. If you cannot see daylight end to end, it is blocked rather than broken.

Could a cracked adapter tube cost suction without leaking water?

Yes. A crack at the cuff where the hose clamps on bleeds air into the vacuum path, which drops suction across the whole machine with nothing wet to show for it. Run a hand around the tube and its joints with the machine running and feel for draw — a hairline under a clamp is easier to feel than to see.
