The Nitrous Express 1/16 NPT tap is a purpose-made tap for installing 1/16 NPT threads needed for nitrous nozzle installs. It provides the basic thread-cutting capability required to prepare intake or nozzle bungs for compatible 1/16 NPT nozzle fittings and is intended for use where a dedicated nitrous nozzle thread is required.
