Radium Engineering 16mm SAE Male Double Banjo Press-Fit Fitting for Nissan RB26DETT

The Nissan RB26DETT is one of the most iconic performance engines ever built, powering the legendary Skyline GT-R. As capable as it is, owners looking to optimize performance often seek improvements in crankcase ventilation and breather systems. That’s where Radium Engineering’s 16mm SAE Male Double Banjo Press-Fit fitting comes in—a precision-machined solution designed to upgrade the OEM valve cover fittings with stronger, more efficient components.

Designed for Intake and Exhaust Valve Covers

This fitting is engineered specifically for the RB26DETT, replacing the factory press-in fittings on both the intake and exhaust valve covers. Each piece features dual 16mm SAE male ports, providing secure and reliable connections for breather hoses or crankcase ventilation lines. Whether you’re refreshing a stock engine or building a high-boost setup, these fittings make it easy to maintain proper crankcase pressure management with confidence.

Press-Fit Installation with OEM-Level Fitment

One of the standout features of Radium’s design is its press-fit installation. This ensures a leak-free seal without the need for modifications, welding, or complicated adapters. The result is an upgrade that installs with the same simplicity as OEM parts, while delivering the durability and performance expected from Radium Engineering. For RB26 owners, that means you get both improved function and the ease of serviceability.

Built for High-Performance Applications

The RB26DETT is often found in high-horsepower, boosted applications where blow-by management becomes increasingly important. The Radium 16mm double banjo fittings provide increased flow capacity for crankcase ventilation, reducing the chance of excessive pressure buildup and oil leakage. Constructed from high-quality materials and precision-machined for exact tolerances, these fittings are designed to withstand the extreme temperatures, vibrations, and pressures of motorsport-level use.

A Clean, Durable Upgrade for RB26 Builds

For enthusiasts who want to keep their RB26DETT running clean and strong, upgrading to Radium’s press-fit fittings is a simple but highly effective modification. They deliver a balance of OEM fitment, leak-free reliability, and improved airflow that benefits both lightly modified street builds and aggressive track cars. Pair these with other Radium Engineering RB26 performance components for a complete, worry-free crankcase ventilation solution.
