Hose end fitting assembly

An end fitting (10) for connecting a hose to an external device, said end fitting (10) comprising:

• a stem (11) adapted to be inserted into an inner channel of a hose and defining a longitudinal axis, said stem comprising an axial bore (13) adapted to convey a fluid therethrough;
• said stem (11) having a plurality of circumferential barbs (12) extending radially outwardly from said stem (11), each of said barbs (12) having a plurality of lands (12a, 12b) at an outer surface thereof, one of said lands (12a) being disposed at an acute angle with respect to the axis of the bore (13) of said stem (11), and a second one of said lands (12b) being adjacent to said first land (12a) and being disposed at a smaller acute angle with respect to the axis of the bore (13) of said stem (11);
• said stem (11) including at least one additional barb (15, 15') having rotating resisting means provided therein to resist rotational movement between said stem (11) and a hose into which said stem (11) is disposed, said first land (12a) of said barb (12) is disposed at an angle of about 2 degrees with respect to the axis of said bore of said stem (11), and wherein said second land (12b) of said barb (12) is disposed at an angle of about 5 degrees with respect to the axis of said bore of said stem (11).

A method of connecting an end fitting of an external device to a hose, said method including the steps of:

• disposing an open end of a hose over an end fitting, the end fitting including a plurality of circumferential barbs (12) extending radially outwardly from the stem (11), each of the barbs (12) having a plurality of lands (12a, 12b) at an outer surface thereof, one of the lands (12a) being disposed at an acute angle with respect to the axis of the bore (13) of the stem (11), and a second one of the lands (12b) being adjacent to the first land (12a) and being disposed at a smaller acute angle with respect to the axis of the bore (13) of the stem (11), the stem (11) including at least one additional barb (15, 15') having rotating resisting means provided therein to resist rotational movement between the stem (11) and a hose into which the stem (11) is disposed and retaining the hose on the end fitting without the barbs cutting the hose;
• and retaining the hose on the end fitting without the barbs cutting the hose.
