This Radium press-in fitting is made for the Nissan RB25DET valve cover and fits either the intake or exhaust side, presenting a swiveling 10AN male connection for hose attachment. The design lets you route a 10AN hose directly from the valve cover where needed, offering a compact, serviceable connection point without altering the cover’s basic form.
