We bought some from McMaster back in 2008....

Each one comes in a pair (red and black) which is nice if you do dual acting cylinders. We had to run two sets of them back in 2008 to operate two different cylinders. The only draw back was how stiff there are to work with (but what do you expect if it self coils). They come with ends that we just cutoff.
