A spare or replacement glass hydrotube for the G Pen Roam portable vaporizer.
This spare glass hydrotube is the beating heart inside the G Pen Roam and facilitates water-cooled filtration to deliver smooth clean vapour through the mouthpiece. The tough glass tube is made from high-quality borosilicate glass. The G Pen Roam offers all the flavours of concentrate dabbing in a hand-held portable vaporizer – without the need for a torch and nail set up.
This replacement glass hydrotube is compatible with the G Pen Roam only and does NOT include the silicone mouthpiece.
