I had to do some work on my Honda that required me to remove the steering pump. Any time you do that, you should replace the top o-ring. This o-ring was an exact match to the original and fit just fine. I popped it in and torqued it down to spec. It's holding a great seal and I've seen no problems with it. Good replacement in that it functions just like it should!
