Description
The Radium Engineering 20-0813 10AN Male Press-In Valve Cover Fitting is a direct OEM replacement for the crankcase fittings found on the top of Nissan RB25DET valve covers — compatible with both non-VVT-i and VVT-i variants. These low-profile 10AN swivel fittings simply press in with no drilling or welding required, making them the ideal solution for routing crankcase ventilation hoses to an oil catch can or AOS on RB25DET builds.
Important: There is one fitting on the intake valve cover and one on the exhaust valve cover. If replacing both OEM fittings, quantity 2 must be purchased. To replace the PCV valve fitting on the side of the RB25DET intake valve cover, use Radium 20-0808 instead.

- Compatible with all RB25DET valve covers — both non-VVT-i and VVT-i variants

- 360° swivel action — Viton O-rings allow free rotation for easy hose alignment

- Anodised and laser engraved — premium finish with permanent part identification
