RBS keeps a full stock of Waterman drop in nozzle jet port nozzle bodies. It is a billet alum. fuel injection port nozzle body that has a very short extension from the end of the threads allowing the end of the nozzle body not to protrude into the airflow in the intake manifold.
These are designed to be used with Waterman or Crawford drop in nozzle jets. The threads are the industry standard 1/8" pipe and they accept -3 hose ends. Can be used with alch. or nitro engines.
Nozzle bodies are measured from tip to first thread for different applications. Racer can choose nozzle body length from drop down menu.
