Straight Connector for hoses

3/16 inch diameter barbed plastic plastic hose connector

Oxygen hoses have a female end on both ends, so need a connector / adaptor to connect to other hoses, the cannulas, etc.
Usually this is done with a fixed adaptor like this one

Or you can use a swivel connector because it helps prevent the hose from tangling, so we offer it as an optional upgrade.
