The present invention is directed towards an improved flexible hose (). The hose () is comprised of at least a flexible material () and a reinforcing rod () positioned externally of the flexible material (). Terminal ends () define both the flexible material () and the reinforcing rod (). At least one terminal end () of the reinforcing rod () is located short of the terminal ends () of the flexible material (), so that the non-reinforced end of the flexible material () forms a soft cuff () adapted to be received by a hose fitting. Also disclosed is an improved method of manufacturing the flexible hose ().

Cuffed hose and method of manufacture

The present invention relates to a hose construction containing a ternary blend. The hose comprises (a) an inner core comprising a ternary blend of (1) from 60 to 85 parts by weight of a low density polyethylene; (2) from 10 to 20 parts by weight of chlorinated polyethylene, chlorosulfonated polyethylene and mixtures thereof; and (3) from 2 to 25 parts by weight of EPDM; (b) a layer of tensioned reinforcement; and (c) an elastomeric cover.
