Suunto QD oring sizes

[Couv]

See if this Leaky Suunto Cobra Quick Disconnect thread has any useful information.

BTW is the part you're looking for on page 66 of this manual?

Hi Couv,

in this thread I found confirmation of the partnumber that I found elsewhere, and it was confirmed again in the parts list on Frogkick. What a fantastic help is that site for schematics.

But as I mentioned before I am starting to doubt the sizes got the oring that was mentioned on the thread. I do not think Suunto uses a size oring that is so hard to obtain.

I keep looking.

I do not think Suunto uses a size oring that is so hard to obtain.

I agree.

Have a look at this old post for ideas on how to determine the correct size.

I have been mucking about with an oring calculator https://oringcalculator.eriksgroup.com/# .
What I seem to be needing is orings of the 1.5mmx4.0mm.

I measured the size of the male end, which is 4.04mm, and the size of the female end is 3.97mm. I cannot measure the groove depth nor width as the space is too limited. I will assume that the cross section mentioned here Leaky Suunto Cobra Quick Disconnect is correct.

So I will order a pack of rings and see where I get.

It will take some time before they get to me in Mexico though, so I will let you know how it goes at some point, just not soon.

At Couv, the size oring for the K5168 is the odd size.

I found a manual for the Suunto quick release in which the sizes are mentioned.

The sizes for the respective rings and partnumbers are:
k5096 1.42mm x 1.52 mm is 003 standard size
k1042 9.25mm x 1.78 mm is 012 standard size
k5168 is 3.8mm x 1.5mm is not any standard size.

I found the manual with the sizes here: http://www.online-divestore.de/shop/Anleitung/schnellkupplung.pdf

When I put the measurements in the oring calculator for the oddball it is hard to get a correct size oring though, it is much easier with a 4mm ID oring.

So I am still going to order the 4mm and try.

I'm looking forward to your findings. Just in case it's a better fit, consider ordering a 3.5 at the same time as the 4.0 to save on the shipping and time.

I will get the 3.5mm as well, but I am fairly sure they will be too small.

I have this description for the O-R in question from a Suunto Manual. But I do not speak fluent O-R. Hope this helps.
Internal o-ring for QR male part (3.80x1.50 90shA) K5168
Myself I would like to know the same location O-R used in the Sherwood/Oceanic HPQD. Anyone?

Hello to all who were awaiting my experiences on this one, here we go.

I ordered both the 3.5x1.5mm and the 4.0x1.5mm. I decided to use the 4.0x1.5mm first, and it works. It was a bit of a nightmare to get the oring in, but after 15 times it went in and it works fine now.

Maybe a next time I will try the 3.5x1.5mm, to see if that is easier to get in and then if it will work as well.
