Quick Couplings
{"Image DocumentName": "Quick Couplings", "Image ImageDescription": "Quick couplings are used for convenience because they can installed and removed by hand and in situations where there will be repeated connecting and disconnecting of lines. There are three kinds of couplings: single shutoff, double shutoff, and straight through. Single shutoffs are used with compressed air. Double shutoffs are used with liquids, and straight through are used where flow must be unrestricted.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
