Hog 2nd oring question

[rsingler]

TBD after I meet folks at DEMA.
I suspect that 2x1 was the design spec, and performance didn't measure up. They changed the oring as an easier solution than redesigning the poppet and balance chamber and only got around to changing the schematic later. Schematics are a low priority for many overseas OEMs.
When I was working with Deep6 on the re-release of their Excursion, we never did get some discrepancies cleared up, and I just overprinted the correct information on the graphics in the manual.

@rsingler is an oracle

But a good oracle

Thank you he who is unable to bring other than goodness to all the people around all the world all of the time

The 2mmx1 orings are defiantly too big.

They are small. I've never seen any fail. I have no idea what their size is, but I bet @rsingler or @cerich does.

hehe. Of course this thread brought me down a rabbit hole. I have almost every single o-ring size I need but this one escapes me. :-( They occasionally fail. Granted this was from a very abused reg.

Does anyone have a good source for these (besides the obvious solution of buying a service kit) in the US?

I’m in on a group buy.

Maybe @LandonL or @cerich can tell us that size?

 

[Candiru]

2.42 x 0.82 mm oring. D6 doesn’t have bulk orings. They come prepackaged in the rebuild kits.

Do you have a source for those O-rings?

The o-ring size was already mentioned above in post #3 by @rsingler so that's not any issue anymore. I was just commenting that do indeed occasionally fail based on your original post. I thought I was going to get away with re-using them but oh well.

Yes or no. On the Classic, a 2.0 x 1.0 is specified on the schematic. That's odd, because on the D2 at least, it's an impossible to find 2.42 x 0.82 mm oring, and the poppets measure out the same to me. Not only that, the D1, Classic and D2 all have the same poppet and balance chamber part numbers.
I found a Precision Associates o-ring that has about the same performance characteristics as the 2.42 x 0.82, but the size escapes me. If you really want to try it, DM me and I'll search for the tests I made.

The size is critical to maintain both a seal and adequately...

It's ultimately a non-issue in the grand scheme of things since they can be purchased as part of a service kit but I like to bulk source my o-rings and since this is a pretty unicorn size o-ring that I can't seem buy in bulk.

I just figured I would post here again in case someone found a common size that does work or if they knew of a reliable place to buy these in bulk.

Unfortunately

unfortunately not
