    is an 0-ring an O-ring is an O-ring (within a Volvo 280 outdrive)?

    I'm replacing some O-rings in my Volvo AQ280 outdrive as I'm replacing exhaust and u-joint bellows. If I happen to have some O-rings from a typical set bought from a hardware store that measure exactly what I'm replacing, would there be any issue in using them? Mainly, I'm speaking of the dipstick and the oil drain plug at the bottom, although I'll be replacing the O-ring at the top of the oil tube between upper (transmission) and intermediate housing as well as the large one between the two as well.

    There are O-rings that are tolerant of petroleum. You don't want your outdrive to get preggers, so rubber is not just rubber when it comes to oils.

      The common o-ring is Buna which is probably what you have and is what is normally used all around. The other most common is viton however these are easily distinguished by their brown color. Both have no problems with petroleum products.

        In my 24 or 25 years working on the AQ series drives, I have found only a few hardwear store O-rings that will replace the OEM Volvo Penta.
        Its not just being petroleum product friendly........, it also has to do with the hardness and the precise thickness of the O-ring.

          I hate paying a brand name premium, but unless you can find another oring with matching specifications, size and material, I’d pony up the bucks. That said, I’m good with brands like Sierra.

            Pete, I agree!
            I’ve had good luck with the Siera brand O-rings!

            The dip stick, drain plug and oil drain back tube O-rings just happen to be among the hardware store O-rings that I have found to work!

            The O-ring that seals around the lower driven gear bearing is not one that I have found.
            I have always used OEM or Siera for these.
