Radium 20-0809 12AN Press-In Valve Cover Fitting Nissan RB26DETT Intake Exhaust

Vehicle Fitment

• Nissan Skyline GT-R R32 (RB26DETT, 2.6L Twin-Turbo I6, AWD - 1989-1994)
• Nissan Skyline GT-R R33 (RB26DETT, 2.6L Twin-Turbo I6, AWD - 1995-1998)
• Nissan Skyline GT-R R34 (RB26DETT, 2.6L Twin-Turbo I6, AWD - 1999-2002)

Fitment Notes

• Fits both the intake and exhaust side valve covers on the RB26DETT - one fitting per cover; purchase quantity 2 to replace both
• This is a direct replacement for the OEM valve cover fittings on the RB26DETT only - not compatible with RB25DET or RB20DET valve cover ports
• For the RB25DET intake side PCV valve port, use Radium 20-0808
• For the RB25DET / RB20DET crankcase vent fittings on top of the valve covers, use Radium 20-0813
• For a double-ended SAE quick connect replacement on the RB26DETT, see Radium 20-0739
• When installed in place of a PCV valve, a new PCV valve must be installed inline or on the catch can to maintain intake manifold connection

Features

• Direct press-fit replacement for both OEM RB26DETT valve cover fittings - no drilling or welding required
• Converts the OEM valve cover port to a 12AN male swivel connection for large-diameter breather lines
• High-flow 12AN sizing suits the increased crankcase ventilation demands of the twin-turbo RB26DETT
• Low-profile design minimizes installed height in the tight GT-R engine bay
• 360° swivel action with FKM O-rings for flexible hose routing even after installation
• Stainless steel and anodized aluminum construction with laser-engraved Radium branding

Product Description

The Radium Engineering 20-0809 is a 12AN low-profile press-in swivel fitting designed as a direct replacement for the OEM valve cover fittings on the Nissan RB26DETT engine, as found in the R32, R33, and R34 Skyline GT-R. It fits both the intake and exhaust side valve covers, converting the factory press-in port to a 12AN male swivel connection for use with large-diameter breather lines in competition catch can and air/oil separator builds. Installation requires no drilling or permanent modification - the fitting simply presses into the existing valve cover port.

The larger 12AN sizing provides greater flow capacity suited to the twin-turbo RB26DETT's increased crankcase pressure output. The 360° swivel design allows the hose to be oriented in any direction after installation for clean, kink-free routing. FKM Viton O-rings ensure oil and chemical resistance for long service life. Both valve cover ports use the same fitting - quantity 2 required to replace both intake and exhaust side fittings.
