Dive Soft Solo ProFlow Limiter hose connector o-ring size, material and durometer

[rvojr]

Does anyone know the specs of the analyzer hose connector o-ring that goes into the flow limiter? Thank you. Mine wore after a while and is now leaking. I'm hoping it isn't an obscure metric o-ring. I looked on Divesoft's website and only found the rebuild o-ring kit.

Divesoft got back to me quickly.:

The size you need is 4mm inside diameter by 1mm cross section. A 70 shore oring works better than a 90. A sheen of PTFE lubricant (krytox, christolube, tribolube, etc) before installing the oring will protect it and make it last longer. Mcmaster Carr does carry them as well.​

I would hit my local Ace hardware. They have a rather amazing amount of this stuff.
After instant gratification fails, order McMaster.

Thanks for posting this (and the response from Divesoft. I also lost one of those little o-rings and nothing I had would fit.

I guess I'll order a lifetime supply of these.

I have a pack of 50 sitting on my counter and I'll let you know that they work and the McMaster number if it's easier.

I may have specified it wrong using their info. The top one is the original on the hose connector. The newer ones are larger but after trying still work. I splurged and got viton ones.
