Abstract:
A rubber vacuum hose, including a rubber middle section that includes an inner layer and an outer layer, but that lacks a support wire. The rubber middle section preferably is able to withstand temperatures of at least two hundred degrees Fahrenheit. The hose also includes two ends attached to either side of the middle section. At least one of the two ends is capable of adapting removably to a vacuum cleaning tool. Preferably, the rubber middle section is flexible enough to be tied into a knot without damage. In a preferred embodiment, the middle section is composed of ethylene propylene, ethylene propylene diene methylene terpolymer, or a mixture thereof suitable to withstand high negative pressure.
