This titanium nail is made for use with a 20mm eNail heating coil but can also be used with just a regular torch. Simply unscrewing and flipping the bottom portion of the nail as demonstrated in the photos allows this nail to fit almost all 10, 14, and 18mm male and female joints so it can be used with almost any pipe you already have. Cleaning is a breeze, just unscrew all the sections and soak them in your favorite cleaner to be back up and running in no time! It is recommended that you season a titanium nail before you first use it and after cleaning.
