I wouldn't trust anything that sells for $12 at Home Depot. Just because your piping is 200' apart doesn't mean it should leak. I have a remote tank over 200' away from my compressor that I leave on all the time. I have a total of about 12 hose reels. I have a ball valve at each hose reel. I have 2 10HP compressors that run alternately and I never hear them running unless air is being used.
