Rubber Washer 72667A

The Rubber Washer (part# 72667A) is a genuine Tacony OEM replacement part from the chassis assembly of the Tornado Marathon SE 900 self-contained carpet extractor. It is the compressible rubber washer that seals a fastened or threaded joint against liquid.

What the Rubber Washer does

Rubber seals by being squeezed into every irregularity in the two faces it sits between, which is why it works on moulded and stamped surfaces that are never truly flat. That only holds while the rubber can still spring back, and springback is what age, heat and cleaning chemistry take away first, long before the washer looks obviously bad.

When to replace the Rubber Washer (72667A)

Replace it when it has flattened and stays flat, when the surface has gone hard, glazed or cracked, or when it has swollen out of shape. A joint that seals only when it is over tightened is telling you the washer has already lost its compression set.

Rubber Washer 72667A — fitment and installation notes

Compress it only until the joint is sealed and then stop, because squeezing rubber flat extrudes it and destroys the seal. Fit it on the same side of the joint the original occupied, check the mating faces for burrs and old debris, and do not add sealant on top of a rubber washer to cure a leak. 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.
