Stihl MS 362 C-M
US model family MS 362 / MS 362 R / MS 362 C-M / MS 362 R C-
Stihl MS 311 / MS 391 — STIHL US catalog lists only 16/18/20" bars (60/66/72 DL) for 3/8" .050"; no 25"/84 DL option. (source)

Stihl MS 461 with its factory .063" bar — UK manual lists 63 cm bars with 1.6 mm (.063") chains only. (source)

What this is
Two replacement chains in the size of Stihl’s 33 RS 84 loop, part number 3623 005 0084: 25”, 3/8” pitch, .050” gauge, 84 drive links. Stihl’s current US catalog lists a 25” bar with this chain size (now sold as 33 RS3 84) for the MS 362 family and the MS 661 family. This pack is the same size.
Check the gauge on your bar first
Big Stihl saws are sold with both .050” and .063” bars, and the two are not interchangeable. Stihl’s own documents disagree on which the MS 362 and MS 661 use: the US catalog lists .050” 25” bars for them, while Stihl’s UK manuals for the MS 362 C-M, MS 441, MS 461 and MS 661 C-M list only .063” (1.6 mm) chains. The gauge is stamped on the tail of the bar. Stihl gives gauge in millimetres too: 1.3 mm is .050”, 1.6 mm is .063”. If yours is .063”, this chain is too thin for the groove.
Oregon calls it 24 inches
Oregon sells its 3/8” .050” 84-link chain, 72LGX084G, as a “24” chain, while Stihl calls the same length 25”. Chainsaw bar lengths are nominal; what has to match is the pitch, gauge and drive-link count.
Fitting it
Stihl’s RAPID Super is a full-chisel professional chain, and Stihl recommends a low-kickback chain wherever one will do the job. Use the bar and chain combinations your saw’s manual or Stihl’s catalog lists.
Frequently asked questions
Will it fit my MS 441 or MS 461?
Only if your bar is .050". Stihl's manuals for those saws list 25" (63 cm) bars with .063" chain only, and a .050" chain is loose in a .063" groove. Check the gauge stamped on the tail of your bar.
Does it fit the MS 311 or MS 391?
No. Stihl's US catalog lists bars only up to 20" for those saws, so there is no 25" setup for this chain.
The listing says 623-005-0084. Is that the Stihl number?
It's missing a digit. Stihl's part for the 33 RS 84 loop is 3623 005 0084. The last two digits are the drive-link count.
Oregon calls its 84-link chain a 24-inch chain. Is it the same?
Same length. Oregon sells its 3/8" .050" 84-link chain, 72LGX084G, as a "24" chain; Stihl calls the same 84-link bar 25". Go by the drive-link count.
