EVIL ENERGY AN10 Female-to-Female Swivel Coupler — Black 2-Pack, 360° Swivel, 1500 PSI

EVIL ENERGY's AN10 female-to-female swivel coupler is a durable, reusable aluminum adapter that joins two 10AN hoses with a 360° swivel for leak-resistant, easy-to-install connections.

This compact union fitting converts two 10AN female ends into a straight, sealed connection using a 37° flare seat and 7/8-14 UNF thread. Machined from 6061-T6 aluminum and finished with a black anodized coating, the coupler is built to handle pressures up to 1,500 PSI and temperatures from -40°F to 250°F. Sold as a pair, the adapters suit performance plumbing where reliable sealing, corrosion resistance, and serviceability matter.

How does this swivel coupler prevent leaks under high pressure?

The adapter uses a 37-degree flare sealing surface that mates tightly with AN10 fittings to form a metal-to-metal seal, reducing leak paths without relying on soft washers. Precision machining and the UNF threaded connection ensure consistent clamping force, and the black anodize adds corrosion resistance to preserve sealing surfaces over time.

• 37° flare sealing for metal-to-metal leak resistance
• 7/8-14 UNF thread for reliable torque and clamp
• Rated up to 1,500 PSI for high-pressure systems
• Black anodized finish protects mating surfaces and reduces galling

Can I rotate hoses after installation without twisting lines?

Yes — the coupler features a 360° swivel joint that lets either side rotate independently after assembly, preventing hose twist and simplifying alignment. That makes routing easier in tight engine bays or custom plumbing runs, and reduces stress on hose ends during operation or maintenance.

• 360° swivel allows hose rotation without disconnecting
• Helps prevent hose kinking and torsion-related wear
• Speeds up installation and realignment in confined spaces
• Reusable design facilitates service and repositioning

What materials and temperature range does the adapter support?

The body is precision-machined from 6061-T6 aluminum, chosen for strength-to-weight performance and machinability. A black anodized surface improves corrosion resistance and wear characteristics, while the construction tolerates typical automotive and racing fluids across a wide temperature span.

• 6061-T6 aluminum for strength and lightweight durability
• Black anodized finish for corrosion and wear protection
• Operating temperatures from -40°F to 250°F
• Suitable for fuel, oil, coolant, and many hydraulic applications (check fluid compatibility)

How do I match this coupler to my existing AN plumbing?

This part is specifically a female AN10 to female AN10 straight union; confirm your hoses or fittings use AN10 flare ends and 7/8-14 UNF threads. Installation requires proper torque and thread engagement; since it seals on a 37° flare, do not use soft sealing materials that might interfere with metal-to-metal contact.

• Intended for AN10 / 10AN flare connections
• Thread specification: 7/8-14 UNF to match AN10 fittings
• Use proper torque and inspect flares for clean, undamaged sealing faces
• Reusable — disassemble, inspect, and reassemble as needed

Who is this for? EVIL ENERGY's AN10 swivel coupler is aimed at automotive enthusiasts, race teams, fabricators, and mechanics who need a compact, high-pressure inline union that simplifies hose routing and maintenance. If you work on performance fuel systems, oil coolers, or custom hydraulic plumbing and require a robust, reusable AN10 connection with rotation capability, this two-piece aluminum set provides a practical, corrosion-resistant solution.
