Thermal Bangers, also called quartz double-wall bangers, provide maximum heat retention and of course a great flavor profile. The double-walled thermal bangers also assist in achieving low-temp dabs done well. The double-walled design allows heat retention to drastically increase and these are more thermally efficient. The hefty sized available bucket allows you to dab large amounts of wax in a single session without losing any. This 18mm male quartz e-banger fits 18mm female joints on your bubbler pipe or dab rig. Get the most from your wax by pairing this quartz nail with a bubble carb cap to cool the vapor and let you savor the tasty terpenes. You will need a torch!
