Glass Bong Adapters are an ideal way to protect and extend the life of your glass bong or dab rig. The purpose of a glass drop down is to absorb the repeated heatings on your glass joints from butane torches or lighters, helping to prevent cracks or breaks on your piece. If you would like to use your dab rig with an electronic concentrate nail or E-nail setup, a drop-down adapter will conveniently place the nail farther away from your face during use. Glass adapters also allow you to switch between various sized pieces and smoking accessories, providing you with the option to use different joint sized pieces collectively. Available in all standard bong and dab rig joint sizes, glass adapters can also easily convert your current water bong into a dab rig.
