If you want to connect two hoses with each other you may require the Air Line Connector. This adaptor has two female hand-tight connections on the both sides.
This hose serves primarily to convey air from one cylinder to another. As the name suggest, it is equipped with a bleed valve to get rid of unwanted air which accumulates inside the hose.
PTFE sealing tape eliminates the need for lubricants and vacuum greases on ground-glass joints, desiccators, and bell jars. It provides a vacuum-tight seal, yet will release readily even after long periods of time.
