Trim o-rings?

[mercrazy]

Is there anything special about these? I hate paying $50+ for 5 o-rings and a $2 seal.
fyi- there’s a cap on eBay for $30 with a much better seal design. I’ve about had it with merc.

I personally dont belive there is anything special
You might be talking about the 3 ram rim since those parts is on ebay,
A lot of metric sizes on the 3 rams
Makes sure you measure the o-rings well as most are JIC sizes as best I could measure
