Radium Engineering 10AN ORB Swivel Banjo to 6.5mm Barb Fitting

Route Your Crankcase Vent Anywhere: A 360-Degree Swivel Banjo Fitting Built for Tight Spaces and Clean Builds

The Radium Engineering RAD20-1000-1065 is a 10AN ORB swivel banjo fitting that transitions from a standard 10AN O-ring boss port to a 6.5mm hose barb, all while delivering 360-degree swivel capability after installation. Machined from stainless steel and aluminum, this fitting is rated to 150 PSI and is safe for all fluids including fuel, oil, and coolant. At an installed height of just 0.797 inches, this fitting is ideal for crankcase ventilation routing, catch can circuits, or any plumbing application where tight clearances demand a compact, high-quality fitting with adjustable outlet direction.

Frequently Asked Questions

This fitting threads into a standard 10AN ORB (O-ring Boss) port. The 10AN ORB uses 7/8-14 thread pitch and seals against a machined boss face with an O-ring, rather than relying on thread interference like NPT. Always confirm your port is a true ORB port before installing.

The barb is sized for 6.5mm inside diameter hose. This is a common size for compact crankcase vent circuits, breather lines, and coolant bleed plumbing in performance builds. Confirm your hose ID before purchasing to ensure a proper seal on the barb.

After threading the fitting into the AN ORB port and torquing it to spec, the barb outlet section can be rotated a full 360 degrees to point in any direction. This eliminates the need to compromise on hose routing or add additional elbow fittings just to clear obstacles in the engine bay.

The installed height is 0.797 inches (20.2mm). This compact profile makes it well suited for applications where valve cover clearance, intake manifold positioning, or firewall proximity would cause problems with a taller fitting.

Yes. The fitting is rated safe for all fluids, including gasoline, diesel, ethanol blends, oil, and coolant. It is compatible with crankcase ventilation circuits that carry oil vapor and fuel mist as well as systems that see positive pressure from forced induction setups.

Yes. With a 150 PSI pressure rating, this fitting can handle the positive crankcase pressures associated with turbocharged and supercharged engines. It is suitable for catch can inlet and outlet lines on forced induction builds.

No. The 10AN ORB design seals via an O-ring against a machined flat face. Thread sealant or tape is not needed and should not be used, as it can interfere with the O-ring seating and cause leaks. The pre-installed O-ring handles all sealing when the fitting is torqued correctly.

NPT (National Pipe Thread) fittings rely on thread engagement and sealant or tape to prevent leaks. AN ORB fittings use a precision-machined boss face and O-ring, providing a more reliable, reusable, and leak-resistant connection especially in vibration-prone, high-pressure, or fluid-immersed environments like engine bays.

Yes. Because the AN ORB design seals with an O-ring rather than by deforming thread surfaces, this fitting can be removed and reinstalled multiple times as long as the O-ring is inspected and replaced if any signs of compression set or damage are present.

Installation Instructions

1. Confirm the target port is a 10AN ORB (7/8-14 thread, machined boss face) before beginning.
2. Inspect the pre-installed O-ring on the fitting. Replace it if it shows cuts, flat spots, or any deformity.
3. Apply a light coat of clean engine oil or O-ring-compatible assembly lube to the O-ring.
4. Thread the fitting into the port by hand until the O-ring contacts the boss face. Do not cross-thread.
5. Torque the fitting to the appropriate specification for a 10AN ORB fitting, typically 20 to 25 ft-lb. Do not overtighten.
6. Rotate the swivel barb outlet to the desired hose routing direction.
7. Slide the 6.5mm inside diameter hose onto the barb and secure with an appropriate clamp.
8. Start the engine and inspect the fitting for leaks before returning to regular use.
