Recovery Dome Gasket X9124

The Recovery Dome Gasket (part# X9124) is a genuine OEM replacement part fitted across both the Tornado and the Powr-Flite self-contained extractor ranges — 2 model records in the manufacturer’s own parts data. It seals the large recovery dome cover against the recovery tank housing, so the vacuum motor pulls air through the hose and the tool instead of leaking it past the lid.

Also known as the Gasket, Large Dome C-Shape SCE.

Compatible Models for the Recovery Dome Gasket

• Tornado Marathon SE 900 self-contained carpet extractor — Model 98170
• Powr-Flite Prowler PFX900S / PFX 900S-T — the same machine under the Powr-Flite name

Symptoms that point at this part

The classic sign is lost suction with no blockage anywhere: the hose is clear, the screens are clean, the motor sounds normal, and the tool still will not lift water. A perished, flattened or torn dome gasket lets the machine draw air straight past the dome, and the recovery tank never develops the vacuum it needs. Look for a gasket that has gone hard and shiny, that has taken a permanent set where the dome clamps down, or that has split at a corner. A dome that rattles or sits unevenly when latched is the same symptom seen from the other side.

Fitting notes

Fit it dry and seated fully into its groove before the dome goes back on. Do not stretch it to length; a stretched gasket pulls thin at the corners and fails there first.
