The tubing on the cuff occasionally comes loose from the palm-type gauge. What can I do to make it more secure?

ADC's 804 series gauge uses a quick release luer slip connector designed to allow rapid selection of the appropriate cuff. To attach, push and twist the tube connector into the gauge air inlet. When properly attached, less than 1/16" of the connector should show and the tubing should remain secure even under the harshest conditions. Do not force as it may be difficult to separate the connector from the port.
