10AN Female to 5/16 Barb 90 Degree Hose Fitting Adapter

caqeg's AN10 female to 5/16" barb 90° swivel adapter is a lightweight, corrosion-resistant aluminum fitting that converts an AN10 (7/8-14 UNF) female port to a 5/16" hose barb at a right angle for fuel, oil, and coolant lines.

This swivel adapter pairs AN-style threaded plumbing with standard 5/16" flexible hose, giving you a compact 90° routing option that reduces stress on lines and creates a cleaner, more accessible installation in tight engine bays or machine compartments. Manufactured from 6061-T6 billet aluminum and anodized for extra wear and corrosion resistance, this two-pack is built for repeated use with gasoline and alcohol-based fuels as well as oil and water applications.

How does this adapter simplify tight routing in engine bays?

The 90° elbow shape re-directs hose runs without sharp kinks, letting you route hoses around obstruction points and back along chassis lines. The female AN10 inlet accepts standard AN male fittings while the 5/16" barb secures flexible hose with a clamp.

• Compact 90° profile reduces required clearance behind fittings
• Swivel body eases alignment during installation
• Barb accepts common 5/16" fuel/hose diameters with clamp retention
• Anodized surface protects threads and external surfaces

What materials and protections does it use for durability?

These adapters are machined from 6061-T6 billet aluminum, a balance of light weight and mechanical strength commonly used in automotive fittings. An anodized finish adds corrosion resistance and surface hardness to withstand vibration and exposure to fuels and fluids.

• 6061-T6 billet aluminum construction for strength and low weight
• Anodized surface resists corrosion and abrasion
• Compatible with gasoline and alcohol-based fuels, oil, and water
• Precision threads to maintain leak-free connections when used with proper sealants or blankets

Will this fitting work with my existing AN hardware and hoses?

The adapter accepts AN10 (7/8-14 UNF) male threads on the female end and terminates into a 5/16" (7.9 mm) hose barb. It is intended for use where an AN-style port must be converted to a flexible hose connection, not as a permanent pressurized flare replacement.

• Female AN10 (7/8-14 UNF) inlet for standard AN male fittings
• 5/16" barb outlet fits common fuel and vacuum hoses
• Best used with hose clamps or crimp-style fittings for secure hose retention
• Not a direct replacement for brazed or welded metal hardlines under extreme pressure

How should I install and maintain these swivel adapters?

Thread the AN end into a compatible male fitting using proper thread sealant or PTFE tape rated for fuel systems if required, then push hose fully onto the barb and secure with a clamp. Periodically inspect clamps and the anodized finish for signs of wear or leakage.

• Use thread sealant compatible with fuel systems when needed
• Ensure hose is seated fully over the barb and clamp is tightened correctly
• Check regularly for leaks, especially after initial run-in
• Replace if anodizing is worn through or if threads are damaged

Who is this for? This two-pack of caqeg AN10 female to 5/16" barb 90° swivel adapters is ideal for motorsport builders, custom fabricators, and hobbyists who need a compact, serviceable way to convert AN10 ports to flexible hose lines. It suits applications in automotive fuel systems, oil feed/return lines, coolant bypasses, and anywhere a durable right-angle hose transition is required. If you need a lightweight, corrosion-resistant adapter that stays compatible with gasoline and alcohol-based fuels and simplifies hose routing in confined spaces, this product is a practical choice.
