Shame I will be cutting them apart, on one end. 
They don't look it in the photos, but the bend is 90 degrees. Should be about 45, as close as I can tell. I have a welder lined up to TIG them back together after I cut them apart. 
Could someone please confirm exact angle of the end piece? I have nothing here to go from, apart from a couple of well aged rubber hoses which I wouldn't trust to be accurate.
