5x pack of Husqvarna O-Ring # 740422100 -  Fits models 61, 66, 162, 266, 268, & 272. This set also fits the Jonsered 625, 630, and 670.

The O-rings go on each side of the crank seal holders. Later saws will only use one of the O-rings as they did not have a flywheel side holder like the earlier saws did.

These are all Buna-N products and are very high quality. I personally have used these on my saws for years with great success. I also have O-Rings for Husqvarna 181, 281, & 288. As well as the 262 and other saws. See my other listings.

I also sell the x-rings in packs of five by themselves as they fit many Husqvarna models.

I also sell these with the X-Ring and O-Ring as a kit so you get both the oiler output x-Ring and the crank seal O-Rings
