Eady to use
Worked well. If you never used a compression fitting go online for instructions. Easy to do but get the sleves in the correct direction.

Great product, saved me tons of time and effort on a hard hydraulic line.
Perfect solution, had a pressure line coming from the hydraulic pump on a 1982 Kubota L245DT that was impossible to remove with the loader and other stuff installed. This coupling system allowed me to cleaning cut it in two, take the part that was leaking (the fitting end) and braze the leak and then used this coupling to join the two sides together since getting around the line would have been impossible to braze back together. Saved me a few hundred bucks and/or major time unbolting the loader and undoing lines to remove the loader and other parts of the tractors to remove the hard line I used this to repair.

Great for transmission lines.
These work perfectly to fix a 3/8" transmission cooler line. The lines needed to be replaced on an old Silverado, as they were leaking from the crimp joint to the rubber hose. The new lines came in and when I got under the truck I realized that I was not going to be able to replace them without dropping the exhaust system and the transmission crossmember. The good news was there was no corrosion on the existing lines from the front of the engine rearward. I was able to cut the old lines in front of the vibration damper and use these compression fittings to match the new lines cut in the same place. Saved hours of work and sealed perfectly. Also priced very reasonably.
