ABSTRACT:
The fitting terminates an end of a high-pressure hose and comprises a coupling having a portion thereof inserted in the hose end, and a sleeve, enveloping both the hose end and the coupling inserted portion, crimped onto the hose end. A void obtains within the sleeve at the end of the hose, and a capillary hole formed in the sleeve (and in a circumferential wall of the coupling) communicates the void with the external surface of the sleeve. The hole, a weep hole, safely relieves fluid leakage or seepage from the void.
