Tornado 98168 Marathon 1200 Gasket 2.63″ O.D. x 1.94″ I.D. 06825

The Tornado Gasket 2.63″ O.D. x 1.94″ I.D. (part# 06825) is a genuine OEM sealing ring, an eighth of an inch thick in 405-duro material. Those three numbers are the part: outside diameter, inside diameter and durometer. Durometer is the one people ignore and the one that matters most — a gasket of the right size in the wrong hardness either will not seal at the clamping force the machine applies, or will not recover after it has been compressed once.

A caution worth reading before you order. The parts book also lists gasket 5781 at 2.6″ O.D. by 1.875″ I.D. — close enough to 06825 that the two are easy to confuse in a parts drawer, and different enough that the wrong one will not seal properly. The inside diameter is the tell: 1.94 inches for this part, 1.875 for 5781. If you have loose gaskets on the bench and no packaging, measure before fitting.

Replace a gasket on sight rather than on schedule. The signs are a permanent flat spot where it has been clamped, a surface that has gone hard and glazed instead of matte and slightly tacky, or any split or nick around the circumference. A gasket that has been in place long enough to take a set will not seal again once it has been disturbed, so if you have separated the joint for any other reason, fit a new one rather than reusing the old.

Clean both mating faces completely before fitting. Old gasket residue is the most common reason a new gasket weeps, because it holds the new one off the face unevenly. Fit dry unless the manufacturer specifies otherwise, and tighten evenly rather than one fastener at a time.

Frequently Asked Questions

What does the Gasket 2.63″ O.D. x 1.94″ I.D. (part# 06825) do?

It is a sealing ring, 1/8 inch thick in 405-duro material. The durometer matters as much as the diameters — the wrong hardness will not seal at the clamping force the machine applies.

Why does this gasket fit only one machine when most parts fit many?

It is genuinely the exception. Most parts on these extractors are shared across the Marathon and MWH families, but this gasket is specific to the Tornado 98168 Marathon 1200. If your machine is a different model, call 763-535-0770 with the serial number before ordering — the near-identical gasket 5781 is the one that fits several other machines.

How do I tell gasket 06825 from gasket 5781?

By the inside diameter. This part is 2.63″ O.D. x 1.94″ I.D.; part 5781 is 2.6″ O.D. x 1.875″ I.D. They look alike loose on a bench and the wrong one will not seal properly — measure before fitting, or call 763-535-0770 with your serial number.
