14mm male domeless ceramic nail 

Despersion: This 14mm Male Ceramic Domeless Nail is designed to convert all of our 14mm and 18mm "dry", female water pipes into Dab Rigs. It features a ribbed design between the cup and the joint which allows heat to dissipate before reaching your glass piece or dab rig. The standard cup size allows this nail to be paired perfectly with our Carb Caps, creating a snug fit to help insulate heat.

Specification: Ceramic as a material is much more ideal than glass when used as a dab nail as it can withstand much more rapid heating and cooling and is comparable to quartz in that regard. The main difference between the two is that ceramic has less thermal conductivity, meaning that it will take more time to heat up but will retain that heat for much longer. Ceramic also requires that you heat the nail evenly in order to prevent cracks
