Abstract

A flexible corrugated hose coupling apparatus is provided for coupling a corrugated hose to a cylindrical neck or sleeve. A resilient hollow cylindrical coupling member has two ends and a generally smooth interior and exterior cylindrical surface and has an annular coaxial bore extending into one end thereof and shaped for threadedly receiving a corrugated hose of a predetermined size to allow the flexible coupling member to be threaded onto the end of a flexible corrugated hose. A clamp can be extended around the resilient hollow cylindrical coupling member for clamping the coupling member and the hose threaded thereinto a coupling neck, such as the neck from a vehicle radiator, so that a flexible corrugated hose can be cut to any length and attach to a smooth or rigid neck with a clamp to achieve a fluid type seal between the corrugated hose and neck.

Claims

1. A flexible corrugated hose coupling for coupling a hose to a cylindrical neck comprising:

a resilient hollow cylindrical coupling member having two ends and a center bore therethrough and having an annular coaxial bore extending into one end thereof and shaped for threadedly receiving a corrugated hose of a predetermined size, said resilient hollow cylindrical coupling member annular coaxial bore extending into one end thereof and having internal and external threads therein matching the internal and external corrugations of a flexible corrugated hose coupling whereby said flexible coupling member can be threaded onto said flexible corrugated hose;

means to allow said resilient hollow cylindrical coupling member to have different size center bores for one corrugated hose of predetermined size whereby one size corrugated hose can be fitted to different size cylindrical necks; and

clamping means extending around said resilient hollow cylindrical coupling member for clamping said coupling member and hose threaded thereinto onto a coupling neck whereby flexible corrugated hose can be cut to any length and attached to a smooth or ridged neck with a clamp to achieve a fluid tight seal between the corrugated hose and neck.

2. A flexible corrugated hose coupling in accordance with claim 1 in which said resilient hollow cylindrical coupling member is made of a resilient rubber compound.

3. A flexible corrugated hose coupling in accordance with claim 1 in which said clamp is a steel band clamp.

4. A flexible corrugated hose coupling in accordance with claim 1 in which said flexible corrugated hose coupling bore has spiraling ridges on both cylindrical surfaces thereof.
