I finally took the time to pull apart my old hose reel to see if I could fix the swivel hub leak. It ended up being a lot easier than I expected and it is nice to have the leak fixed so the air compressor doesn't keep kicking on. I go over the process step by step as well as the tools and parts needed. One thing to note is my o-ring sets have their own numbering system. The actual number of the o-ring is 112.
