Question What is the life expectancy of a ECCR?

There are plenty of places that make custom o-rings for cheap, so that will never be an issue.

Yeah good luck with that in a CCR. Once even the simplest Oring isnt supported anymore the rest of the unit also needs significant work/refurbishment too

Depends on where the O-ring is at. Something like a DSV, just swap the DSV for a different make.

It all gets down to the details. And at that point, it isn't even an eCCR issue anymore. It is just a CCR in general issue. Or even any other mechanical thing that needs a special service part. And can part of it be adapted to something else? Look at Cuba. American cars from the 50s, staying on the road using 80's Russian tractor parts.

Nice, good to know

No worries. In fact, its a good idea when removing the head and checking the o-rings, to remove them, check for damage and lubricate lightly, then replace with the "corners" offset a bit (an inch or so) which will help prevent those "square" parts from becoming excessively worn. Not a big problem if you don't but that's where they tend to start getting fine cracks after a couple of years. Also, they are 2 different sizes so make sure you put 'em back where you found 'em.

Why wouldn’t a custom o-ring work?
