Packaging is a problem for a good product
These are a quality fitting, however when they package them they put the ferrules inside the fittings and then screw them down. This puts small nicks in the edges of the ferrules making some of them hard to slide over the tube. They should be packaged separately inside the bag to avails this. Otherwise they work great and are a good deal

Perfect for 3/8" Oil Fuel Line
Just what was needed to connect one way check valve into my existing oil fuel line. One on each side and the check valve in the middle. No leaks works well.

As described , but 10mm wrench needed to tighten
They fit and with teflon tape on the pipe thread dide the sealed well. The wrench size id 10 mm not 7/16" like most USA one. I need something to atach a oil pressurs gage to mr 8N tractor that was not 1/8" size. With one of these and a double femail pipe fitting I made it work. The price was cheaper ans anything on Ebay ans they worked

Fit as expected.
Fittings work well with matching tubing. Redid the top end of my air compressor again and got it all hooked up.
