Abstract
Abstract The present invention relates to a plastic abrasion resistant protective sleeve for covering a radiator hose. The sleeve of the invention has a corrugated external surface comprising a plurality of projections and troughs formed in said sleeve. The projections are substantially evenly distributed and have a substantially uniform size. The sleeve has a slit along its longitudinal axis which provides for easy application to or removal from the hose, and is made of plastic that is substantially unaffected by high temperatures. A method of using said protective sleeve for protecting a radiator hose from abrasion also is provided.
