Abstract
A reformable, shape retentive hose having a precured tube located in a hose sidewall, and a reformable rod inserted in the precured tube.

Claims13
In a method for making elastomeric hose by the steps of forming a curable hose subassembly with a tube having a bore, reinforcement and cover that together characterize a sidewall of the hose;
- placing the hose subassembly in a mold;
- pressurizing the bore and expanding the hose subassembly against the mold and forming the hose subassembly to a desired exterior shape;
- and curing the so formed hose subassembly into a cured hose;
- the improvement comprising the steps of:
- placing at least one precured tube in the side wall during the step of forming the hose subassembly so that the tube is longitudinally oriented with the hose subassembly;
- curing the hose subassembly and embedding the precured tube in the hose sidewall;
- and
- inserting a reformable rod in at least one precured tube and defining a formable hose with curved shape retentive characteristics.
