The Moroso -12AN female non weld-on valve cover fitting with baffle is supplied as a single fitting to add a female -12AN port to valve covers without welding. The baffle reduces oil migration while allowing AN-style hose attachment for ventilation or catch-can plumbing, useful in custom engine breathing setups where a threaded interface is required.
