Compact, Clean, and Built to Perform

In modern performance builds, space is always at a premium. Whether you’re working in a cramped engine bay, plumbing a catch can system, or re-routing fuel and oil lines, the way you manage fittings makes all the difference between a professional-grade setup and a messy, leak-prone nightmare.

That’s where Radium Engineering’s 10AN Male Swivel Banjo – 11.8mm Press Fit Fitting comes in. This component may look small, but it solves big problems for tuners and fabricators by providing a low-profile, high-strength, and fully swiveling connection point. Designed for tight clearances and harsh conditions, it’s an elegant solution for clean, reliable fluid routing in high-performance applications.

The Press-Fit Advantage

Traditional fittings often require welding, drilling, or bulky adapters that can be tough to fit in tight spaces. The Radium 11.8mm press-fit body provides a secure connection without the need for permanent modifications.

Why Press-Fit Works

• Quick Installation: No welding or fabrication needed.

• OEM-Like Fitment: Designed to lock into place with a precision interference fit.

• Serviceable: Can be installed cleanly and removed without permanent changes.

• Leak-Free Seal: Engineered tolerances ensure no gaps under pressure.

For builders who want a balance of convenience and reliability, press-fit fittings are a go-to option.

10AN Male Connection: The Standard for High-Performance Plumbing

The fitting integrates a 10AN male connection, the standard size used across motorsports for oil, fuel, and coolant lines. Why does that matter?

• Universal Compatibility: Works with countless AN hoses, fittings, and adapters.

• High Flow: Large diameter supports heavy fluid flow required by high-horsepower setups.

• Ethanol and Oil Safe: With the right hoses, it’s ready for any fluid type.

• Durability: AN fittings are far more reliable than barbed or push-lock solutions in race environments.

For anyone building or modifying a high-performance system, AN lines are the standard—and this Radium fitting integrates seamlessly.

The Swivel Banjo Design

What sets this component apart is the swiveling banjo fitting. The anodized aluminum 10AN male head rotates a full 360 degrees after installation.

Benefits of the Swivel Banjo:

• Reduced Hose Stress: Allows hoses to naturally align with routing, preventing kinks.

• Easy Adjustments: Re-angle hoses during service without removing the fitting.

• Compact Profile: Banjo design keeps height low, perfect for engine bays with tight clearances.

• Professional Look: Clean, tucked lines with less clutter.

This is especially valuable in engine bays where multiple systems—fuel, oil, crankcase ventilation—need to coexist without interference.

Materials That Withstand Abuse

Like all Radium Engineering products, the materials are chosen with performance in mind:

• Stainless Steel Press-In Body: Corrosion-resistant, heat-resistant, and capable of withstanding high pressures.

• Anodized Aluminum Swivel Head: Lightweight, durable, and resistant to fuel and oil exposure.

• High-Precision Machining: Tight tolerances ensure no leaks and long service life.

This mix of stainless steel and aluminum gives strength where it’s needed most, while keeping weight low and flexibility high.

Applications: Where This Fitting Shines

The Radium 10AN Male Swivel Banjo Press Fit Fitting can be used in a variety of high-performance setups:

• Valve Covers: Perfect for adding or upgrading breather and catch can connections.

• Crankcase Ventilation: Provides a high-flow, low-profile outlet for -10AN lines.

• Fuel Systems: Ideal for compact fuel line routing in custom builds.

• Oil and Coolant Lines: Works in auxiliary systems where space constraints exist.

• Custom Fabrication Projects: Gives fabricators a versatile solution without resorting to welding.

Whether you’re upgrading an RB, JZ, LS, or any other platform, this part adds professional-grade plumbing in places where other fittings won’t fit.

Why This Matters for Tuners and Fabricators

It’s easy to underestimate fittings until they fail. A cheap hose barb might save money up front, but it won’t survive long in a 600hp drift car or a time-attack machine running E85.

This Radium fitting offers:

• Reliability: High-pressure capable and leak-proof.

• Flexibility: Swivel and press-fit design simplify routing and future changes.

• Space Efficiency: Compact banjo design is made for modern, crowded engine bays.

• Professional Finish: Your build looks as good as it performs.

For tuners, it means fewer headaches and more time focused on tuning instead of chasing leaks. For fabricators, it means easier installs and cleaner customer builds.

Radium Engineering: Why Trust Them

Radium has carved out a niche as one of the most trusted names in high-performance fueling and plumbing systems. Their strengths include:

• Platform-Specific Parts: Many of their fittings and kits are designed for exact applications.

• Precision Manufacturing: Every part is CNC-machined to tight tolerances.

• Motorsport Testing: Parts are track-tested in drift, time attack, and endurance racing.

• Integration: Radium fittings often work as part of a complete ecosystem, from rails to regulators to catch cans.

When you choose Radium, you’re not improvising—you’re using components designed for performance and reliability from the ground up.

Alternatives: Press-In vs Weld-On vs Barb

To highlight why this fitting is so valuable, here’s how it compares to other common solutions:

The Radium press-in with swivel banjo hits the sweet spot: stronger than barbs, easier than weld-ons, and cleaner than bulky adapters.

Who Should Use This Fitting?

• Street Builds: Clean catch can routing without hacking valve covers.

• Track Cars: Reliable under heat and sustained high RPM.

• Drift Cars: With constant throttle modulation, crankcase ventilation needs to be strong and flexible.

• Fabricators: Building customer cars with professional-grade plumbing.

• DIY Tuners: Want OEM-like fitment with aftermarket functionality.

If your build involves tight spaces and serious power, this part belongs in your plumbing arsenal.

Final Thoughts

The Radium Engineering 10AN Male Swivel Banjo – 11.8mm Press Fit Fitting might not grab headlines like a turbo upgrade, but it’s the kind of detail that separates reliable, professional builds from thrown-together projects.

By combining a secure press-fit design with a swiveling 10AN connection, it provides a compact, leak-free, and flexible solution for crankcase ventilation, catch cans, or fuel/oil routing. Built from stainless steel and anodized aluminum, it’s engineered for the abuse of real motorsport while looking clean enough for any show bay.

For tuners, fabricators, and enthusiasts, it’s one of those small upgrades that makes a big difference in the long-term performance and serviceability of your build.
