"these are the best thing that speed fit ever invented. you can you them time and time again, just remember to cut the pipe with a clean edge so you dont damage the rubber seal.very handy to keep in your pocket as you can instantly stop or prevent a water leak. i use them for pressure testing a system up to 6 bar!"
