Seems like high quality. Only problem was ordering the 38mm length was a boneheaded move on my part. Don’t know if or when I’ll ever have a use for it. I like it better than the one that came with my Galfer brake lines. If it wasn’t too long, I’d definitely use it instead.

Buy an extra one and send it back after you take out ONE of the copper crush washers because you NEED THREE… IT SAYS IT COMES WITH 3 But you ONLY GET 2 !!! Lost 2 Stars because of the extra un needed BS! These have hollowed/lightened bolt heads which are “cupped” on top not flat… Otherwise adequate

Connected two brake lines to a KLR 650 rear master cylinder for a sidecar project.

used it to bypass the antilock on my hardley. Seems that when a hardley antilock system fails you will no longer have any brakes at all. That is some effed up engineering from hardley.

I bought used SS brake lines but they didn’t come with the right banjo bolt. I ordered this one and it fit my 09 Yamaha r6 perfectly.

It’s a fine piece of hardware the only caveat is it is about 2mm too long for me and I can’t return it. Brand new, in original packaging never installed… Can’t return. Badaboom.
