Product Description

The Radium Engineering 20-0812 is a 10AN banjo press-in swivel fitting designed as a direct replacement for the exhaust side crankcase vent barb on the S14 and S15 Nissan Silvia SR20DET valve cover. It converts the factory exhaust side press-in port to a 10AN male swivel connection for large-diameter breather lines used in catch can and air/oil separator setups. No drilling or permanent modification is required - the fitting simply presses into the existing valve cover port.

The 360° swivel allows the hose outlet to be oriented in any direction after installation for clean, routed catch can plumbing. FKM Viton O-rings ensure long-term chemical resistance to oil vapors. Builders should note this fitting is exclusive to the S14/S15 exhaust side port - the S13 SR20DET uses a different exhaust side fitting (Radium 20-0811), and the S14/S15 intake PCV port requires Radium 20-0808.
