Glass Adapters are optional attachents for smoking pipes and water pipes. Glass smoking pipes have three standard joint sizes: 10mm, 14mm and 18mm. Joints also come in different "genders" male or female. Female pieces fit with male pieces and vice versa. Glass Adapters convert one size to a different size, one gender to the other gender, or a combination of size and gender changes. If you find yourself with a bowl or nail that doesn't fit your water pipe, just add one of our glass adapters to make it fit!
