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
What port size does the RAD20-1000-1065 thread into?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.
What hose size fits the 6.5mm barb outlet?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.
How does the swivel function work on this banjo fitting?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.
What is the installed height of this fitting?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.
Is this fitting safe for use with fuel and fuel vapors?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.
Can this fitting handle boost pressure?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.
Does this fitting need thread sealant or Teflon tape?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.
What is the difference between this fitting and an NPT barb fitting?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.
Is this fitting reusable if I need to change my hose routing?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
- Confirm the target port is a 10AN ORB (7/8-14 thread, machined boss face) before beginning.
- Inspect the pre-installed O-ring on the fitting. Replace it if it shows cuts, flat spots, or any deformity.
- Apply a light coat of clean engine oil or O-ring-compatible assembly lube to the O-ring.
- Thread the fitting into the port by hand until the O-ring contacts the boss face. Do not cross-thread.
- Torque the fitting to the appropriate specification for a 10AN ORB fitting, typically 20 to 25 ft-lb. Do not overtighten.
- Rotate the swivel barb outlet to the desired hose routing direction.
- Slide the 6.5mm inside diameter hose onto the barb and secure with an appropriate clamp.
- Start the engine and inspect the fitting for leaks before returning to regular use.

Fabrication
Fabrication parts and materials provide the raw components needed to build, repair, and modify custom exhaust systems, turbocharger plumbing, intercooler piping, fuel system lines, oil routing, and engine bay heat management on performance and competition vehicles. Stainless steel tubing, titanium tubing, aluminum charge piping, mandrel bends, pie cuts, flanges, merge collectors, V-band clamps, O2 sensor bungs, AN fittings, PTFE hose kits, braided fuel and oil lines, heat shields, and welding supplies are the backbone of any serious custom fabrication project. Professional fabricators, race team mechanics, and advanced DIY builders who want full control over exhaust routing, charge pipe layout, or fuel system plumbing choose raw fabrication materials rather than pre-bent kits because custom fabrication allows fitment solutions that no universal kit can accommodate. Brands including Vibrant Performance, Ticon Industries, Stainless Bros, Radium Engineering, Fragola, and DEI provide th...

Fittings
Automotive fluid system fittings are the hardware that connects hoses, hard lines, and components within fuel, oil, cooling, brake, power steering, and intercooler circuits, and the quality and correct sizing of these fittings directly determines whether a high-performance fluid system remains leak-free under the pressure, temperature, and vibration conditions that race and street performance environments produce. The AN fitting standard, derived from military Aircraft-Navy specifications, provides a consistent thread and flare geometry across fuel, oil, and hydraulic applications that allows interchangeability between brands and simplifies system design by providing a known thread engagement and sealing approach for every connection. Swivel fittings, bulkhead adapters, 45-degree and 90-degree elbow fittings, tee and union adapters, and reducer fittings allow performance builders to route lines through tight spaces and around obstacles while maintaining correct flow area without res...
