EVIL ENERGY 6AN Flare to 8AN ORB 90° Swivel Adapter — Matte Black, 6061-T6 Aluminum, O-ring Seal

Compact 90° swivel adapter that converts a 6AN 37° flare connection to an 8AN ORB male with O-ring sealing for leak-resistant fluid routing in tight spaces.

This machined aluminum adapter from EVIL ENERGY lets you join a 6AN flare hose to an 8AN ORB port while rotating the fitting for easier hose alignment. Constructed from 6061-T6 aluminum and finished in matte black, the piece combines lightweight strength with corrosion resistance. The 6AN side seals on a 37° flare angle, while the ORB male end uses an NBR O-ring to form a pressure-tight seal. Designed for oil, fuel, water, coolant, and air applications, the swivel function reduces hose stress and simplifies installation where clearance is limited.

How does this adapter create a secure seal between flare and ORB fittings?

The adapter uses two proven sealing methods: the flare side seats on a 37° cone to compress metal-to-metal, and the ORB male end compresses an NBR O-ring in its bore for a resilient seal. Together they offer reliable sealing across a range of fluids without extra washers.

• 6AN flare side: 37° seating angle for metal-to-metal seal
• ORB side: NBR O-ring provides elastomeric sealing
• Thread standard: 6AN flare thread is 9/16-18 UNF
• Swivel function: allows rotation for hose alignment without twisting

What materials and finishes are used, and why do they matter?

The adapter is CNC-machined from 6061-T6 aluminum, chosen for its strength-to-weight ratio and corrosion resistance. A black surface finish adds protection and a professional look while helping resist oxidation in typical engine-bay environments.

• Body: 6061-T6 aluminum for durability and light weight
• O-ring: NBR (nitrile) for broad compatibility with oil and fuel
• Finish: black coating improves longevity and aesthetics
• Manufacturing: precision machining ensures accurate thread fit

When should I choose a 90° swivel adapter instead of a straight fitting?

Pick this 90° swivel adapter when space constraints or hose routing require a sharp directional change and you want to avoid kinking or twisting the hose. The swivel action lets you orient the hose after tightening, simplifying installations where access is limited.

• Ideal for tight engine bays and compact assemblies
• Prevents hose stress by allowing post-tightening rotation
• Saves time when aligning hoses to ports at awkward angles
• Useful in retrofit work where flange orientation differs

Is this adapter compatible with my system fluids and pressures?

Designed for general automotive and industrial fluids, the adapter suits oil, fuel, coolant, water, and compressed air systems. The NBR O-ring and aluminum construction are compatible with most non-corrosive media, but check fluid and temperature limits for your application before use.

• Compatible fluids: oil, fuel, coolant, water, air
• Not recommended for strong oxidizers or incompatible chemicals
• Confirm temperature and pressure requirements against NBR limits
• Use appropriate sealing lubricant when installing the O-ring if needed

Who this is for: This EVIL ENERGY 6AN to 8AN ORB 90° swivel adapter is aimed at car builders, motorsport tuners, DIY mechanics, and equipment technicians who need a compact, high-quality transition fitting to route hoses in tight spaces. It suits anyone converting between flare and ORB connections, performing retrofits, or seeking a rotatable, leak-resistant solution for oil, fuel, coolant, or air lines.
