Minimum order length of any one color is 10 feet.  They provided me with samples of most of their colors so I could illustrate the function of the various vacuum hoses and also so you could see the colors available.  The color in this photo is a bit off; the orange is very bright fluorescent orange.  The green is also a bright fluorescent.  The rest of the colors are pretty true.  Available also in black and silver.  It's very high quality, thick-wall tubing that should last a lifetime.
