Gasket X9084

The Gasket (part# X9084) 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 the compressible gasket that seals a mating joint in the tank assembly.

What the Gasket does

This gasket has to seal two things at once on an extractor, liquid on one side of the joint and vacuum on the other. Vacuum leaks are the quieter failure of the two, because the machine keeps running and simply picks up less water per pass, and the operator blames the wand or the motor long before anyone looks at a flat gasket.

When to replace the Gasket (X9084)

Replace it when it has taken a permanent set and no longer springs back, when it is torn or nicked at the edge, or when the joint weeps after being tightened correctly. Chemical hardening leaves it glassy and cracked, which is easy to spot once the joint is opened.

Gasket X9084 — fitment and installation notes

Fit the gasket dry unless the service instruction says otherwise, and never build a seal out of sealant on top of a tired gasket. Clean both faces down to bare material, and tighten the fasteners evenly around the joint rather than fully seating one before starting the next. 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.
