CEJN fitting strip-down

Thank you for your reply.
I suspect it to be the right one.
Primus will send me a couple of spindle o-rings replacements that I will immediately try to mesure.
I am based in France where I could find the ones with the mesures mentioned up here for 1 euro (for a set of two). NBR good quality ones.
No more repair kits for me. Enough spares for all the other parts.

 

Once I was touring in Morocco, I already bought a dozen of them in a very simple hardware shop for almost nothing. I brought an original one, put it on the table and compared. One size matched. I used them for years and never had an issue. They worked perfectly and lasted much longer than the original ones. As well, no idea if they were NBR or not.

 

I just received 2 orings from Primus and ordered others from Amazon with the references mentioned on this thread.
Clearly the same ones.
By the way, Primus didn't share any measurements even though I asked for.
If it can help.

With all the different profiles, it does confirm they match.

 

Same

Measurements might be, but, color indicates different material.

Just saying

 

Yes, obviously different colour but if you read the amazon description link, it fulfills all the requirements. It's NBR 70.
On the Primus page, they simply mention NBR. In terms of safety, it's the most important.
The original blue ones failed much faster than very very cheap ones I bought in Morocco. (Black ones too)
I am using this stove intensively.
