Sorry to resurrect such an old thread but I've referenced it a few times and I have a question.
I want to put together a rebuild kit for my S5. I was looking to get the o-rings from markerkits.com.
There are a few 90 durometer rings in the kits but I only see 70 at markerkits.com. Could I use the 70's or is there a place I can get everything I need for my S5?
