Now you can run your NOVA through water with class and dignity! Made from wood and glass, the LiNK reroutes the vapor into your favorite water piece for an even better experience! It cools the vapor and brings out the terpenes. The V1 is desiged for use with most water pieces, whether you have a center mounted stem like Sneaky Pete's globe, or an angled mount like most classic water pieces. Each LiNK V1 comes with a 14mm male stem and 2 high temp silicone O-rings.
