20-Pack Orbit 58087N Zinc Shut-Off Coupling

I use these on the front and rear hose bibs of my house and pretty much leave them there all summer. They come in real handy during my annual power washing of my siding project. Power washing uses a lot of water. I want to turn the water off and on frequently so I can reposition my equipment and not waste so much. They're five stars for that reason. This year I had a couple of these couplings from last year that failed. It looks like I left them outside too late in the season last year and they got water inside that froze and ruined them. Keep in mind that you might want to take these out of service in early fall and make sure they get a chance to dry out thoroughly before frost threatens.
