    I now carry the full set in my truck at all times. It came in a hard case that protects and organizes the Flagelocks so I don't have to hunt for them in a bag of tools. They are definitely worth every penny.

    "We have two or three sets of Flangelock. Our mechanics use them all the time in the shop and the field. They are very convenient to use on any hydraulic lines and especially minimize the amount of clean up needed compared to the old way we used to do things. I highly recommend them anytime I get an opportunity."
  • Ken (TX)
    "Goodbye dirty rags! We have always just stuffed a rag in the open flange and dealt with any mess after we were done with the job. Flangelock ended that. This product has almost eliminated cleanup for us. Love it!"

    "FlangeLock tools have been a solution to the challenge of dealing with hydraulic connections. They minimize the chance of costly spills and contamination to hydraulic systems. I STRONGLY RECOMMEND FLANGELOCK TOOLS"
