This Pulsar Glass Cartridge Adapter is available with multiple different joint sizes so you can adapt almost any water pipe to work with your vaporizer cartridge. This rig joint functions best with pipes that have a 90° angle joint. Simply slip the mouthpiece of your vaporizer cartridge into the open joint of this adapter and use the metal joint clamp to secure it in place (some vaporizers may be heavier than clamp can support).
