Abstract: An anti-debris device releasably engages and covers an unconnected end of a fluid-conveying quick disconnect connector to prevent debris intrusion. The device comprises a boot defining a cavity shaped to receive the connector, a connector-receiving access opening to the cavity, and a closure member such as flexible sheet slit to form resilient fingers movable between an opening-covering position preventing intrusion of foreign matter when the boot is not being used, but that flex to a connector-receiving position when an unconnected portion of a connector is biased against the closure member. The fingers assist in retaining the device on the connector. Various embodiments allow retaining the anti-debris device to a particular connector when the device is not in use, and/or for storing/protecting multiple connectors. Related methods are also disclosed and discussed.

Abstract: A shutoff valve for the downspouts of fuel trucks or tankers, the shutoff valve being installed at the inlet of a downspout and serving to seal off the inlet of the downspout until such time as overflow fuel or other liquids can be safely drained off from an overflow liquid well provided at the top of the tank. The valve includes manually actuatable means for opening the valve and also includes means for automatically closing the valve in the event of a fire.
