10AN Female to 3/8 Barb Hose Fitting Adapter Straight

A pair of caqeg AN10 (7/8-14UNF) female to 3/8" (9.5mm) hose barb straight swivel adapters made from 6061-T6 billet aluminum with anodized finish for durable, corrosion-resistant hose connections.

These straight swivel adapters convert AN10 female threaded ports to 3/8" hose barb fittings for use with fuel, oil, coolant, and other automotive fluid lines. Machined from lightweight 6061-T6 aluminum and anodized for added toughness, the fittings are built to withstand vibration and exposure to gasoline and alcohol-based fuels. Each pack includes two identical adapters, ready to install in custom plumbing, repair, or retrofit projects where a reliable barb-to-AN connection is needed.

How do these adapters make custom fuel or oil lines easier to build?

They let you join 3/8" flexible hose directly to an AN10 female port without cutting or special tools beyond hose clamps. The straight swivel design simplifies alignment and helps prevent hose twisting during installation.

• AN10 female thread (7/8-14UNF) mates with standard AN fittings.
• 3/8" (9.5mm) barb accepts common fuel and oil hoses.
• Straight swivel body eases hose orientation and tightening.
• Sold as a pair for dual-line or spare use.

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

The adapters are CNC-machined from 6061-T6 billet aluminum, chosen for its strength-to-weight ratio and machinability. Anodized surface treatment increases abrasion resistance, improves corrosion protection, and gives a uniform black appearance that resists chipping.

• 6061-T6 aluminum for a balance of durability and light weight.
• Anodized finish adds corrosion and wear resistance.
• Precision threads and barbs for leak-minimizing fit.
• Compatible with gasoline and alcohol-based fuels.

Will these fittings work with my vehicle’s fuel system or coolant setup?

They are designed for a wide range of automotive fluid systems including fuel, oil, and water lines, but compatibility depends on thread size and hose inner diameter. Confirm that your female port is AN10 (7/8-14UNF) and your hose is 3/8" (9.5mm) I.D. before installing.

• Use with hoses rated for targeted fluid and pressure.
• Clamp hose securely over the barb to prevent leaks.
• Avoid use where extreme pressure or high-temperature seals are required without additional fittings.
• Works with gasoline and alcohol-based fuels as specified.

How should I install and maintain these adapters for reliable service?

Installation is straightforward: hand-thread into the AN10 female port, tighten to proper torque, slide hose over the 3/8" barb, and secure with a hose clamp. Regular visual checks and retightening of clamps will keep connections secure and leak-free under normal automotive conditions.

• Lubricate threads lightly for smooth engagement and torque control.
• Use a quality hose clamp sized for 3/8" I.D. hose.
• Inspect periodically for abrasion, leaks, or corrosion signs.
• Replace if threads, barbs, or anodizing show significant wear.

Who is this for: These caqeg AN10-to-3/8" barb adapters are ideal for automotive enthusiasts, DIY mechanics, custom fabricators, and race teams who need dependable, lightweight fittings for fuel, oil, or coolant plumbing. Choose this pack if you require a straight, swivel-capable adapter in a compact, corrosion-resistant aluminum form for retrofits, repairs, or one-off builds.
