Fits Perfect! I bought this to replace a hose my husband accidentally melted. I was hoping it would fit our 5 gallon Vacmaster VOC507PF - and it does! Aha! Fits right, sucks well, length is as described. The material of the hose does not appear brittle or too hard. This is exactly what I was looking for in a hose and it is actually slightly longer than the one that came with the original unit making cleaning my car a breeze, GOOD!
