摘要： A hose fatigue indicator including a hose fitting defining an opening. A fracturable diaphragm is positioned adjacent the opening. The diaphragm is in communication with fluid flowing through the fitting. The diaphragm fractures upon exceeding a predetermined fatigue limit due to exposure to the fluid flowing through the fitting. Indicator means provides an indication that the diaphragm has fractured.
