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.
