Why do you want a short path vessel -> get rid of surface area traps. Short path vessel that holds no water maximizing your consumption per session with your device. this is the new model that is compatible with the mooselabs mini filter, and my whip connect kit Never pull or push on the tip/neck bend of the attachment to insert it in, or take it out of the device or risk breaking the tip of the attachment Do not try to put the whip on while the attachment is inserted into your device. Before putting either the latex or silicone whip back onto the tip of the glass attachment, be sure to wet the glass tip and tube first, as to minimize resistance. Do not try to force the whip on dry. although it is a firm fit, you will be able to twist either whip onto the tip once it is wetted Wiggle the attachment in or out of the device grabbing onto the bump near the bottom of the attachment-> your hand underneath the neck of the tip vs over (as to ensure you don’t accidentally press down on the tip) * or risk breaking the tip of the attachment *
