Was about to order direct from Amazon but was given the option of getting it direct from Duda Energy for $2 less and free shipping, which I accepted. Arrived on the second day during lunch. Exactly what I expected, except that the OD is slightly larger than 1/2 inch. The Amazon description is 19/32", which I have no reason to doubt. The product is perfect, except for a strong odor of unreacted long-chain alcohol from the plasticizer. This is not an issue since I am using it to replace an AC condensate line not in the living space of the home. The tubing is labeled not for food contact. I expect the odor to dissipate with time. My first condensate line, clear unreinforced vinyl, lasted 19 years until it got so disreputable-looking that I replaced it. When I yanked that old line out today it was still sound, although opaque and tacky. I expect this new line to outlast me.
