The Gasket (part# X9740) is a genuine Tacony OEM replacement part from the recovery and solution tank assembly of the Tornado Marathon SE 900 self-contained carpet extractor. It is a sealing gasket in the tank assembly’s vacuum and solution path.
What the Gasket does
This gasket seals a mating joint in the tank assembly, keeping the vacuum circuit airtight and stopping solution from weeping at the seam. Because the extractor develops all its lift through sealed joints, any gasket that stops sealing turns directly into lost suction at the wand rather than an obvious leak.
When to replace the Gasket (X9740)
Replace it when the rubber has hardened, flattened, cracked, or holds a permanent impression of the joint. If it does not spring back when pressed with a fingernail, it has finished its service life. Damp streaks along a seam after a shift are the visible confirmation.
Gasket X9740 — fitment and installation notes
Clean both faces back to bare material before fitting. A single grain of grit under a new gasket holds the joint fractionally open and reproduces exactly the leak you set out to cure. Tacony builds the Tornado Marathon SE 900 and the Powr-Flite Prowler PFX900S on a single machine platform, so this component carries across both brands rather than belonging to either one. It is a shared Tacony component and may fit additional models beyond those listed — call us and we will confirm against your serial number.
