8AN Female to 3/8 Barb 90 Degree Hose Fitting Adapter

caqeg's AN8 female to 3/8" barb 90° swivel fittings are lightweight, anodized aluminum adapters engineered to connect AN8 (3/4-16UNF) lines to 3/8" hose runs at a compact right angle.

When routing fuel, oil, or coolant lines in tight spaces, a reliable low-profile adapter can make installation neat and leak-free. These swivel 90° fittings are machined from 6061-T6 billet aluminum and anodized to resist corrosion, while the barbed outlet accepts standard 3/8" (9.5mm) hose for common automotive and motorsport uses. Sold as a pair, they offer a cost-effective way to adapt AN8 female fittings to hose systems without bulky unions or hard pipe bending.

How does this 90° adapter help with tight routing in engine bays?

The compact elbow redirects flow at a right angle so hoses can clear brackets, turbochargers, or manifold surfaces. The swivel feature lets you orient the barb after the fitting is tightened, reducing hose twist and stress.

• Right-angle profile minimizes hose interference in cramped areas.
• Swivel female AN8 connection enables final positioning without loosening the mating end.
• Barbed 3/8" outlet secures standard fuel or oil hose with clamps.

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

These adapters are milled from 6061-T6 billet aluminum, a common choice for strength and light weight in automotive fittings. An anodized surface finish improves wear resistance and helps prevent corrosion when exposed to fuels and road contaminants.

• 6061-T6 billet aluminum for high strength-to-weight ratio.
• Anodized coating for enhanced durability and corrosion protection.
• Compatible with gasoline and alcohol-based fuels without degradation.

Which applications are these fittings suited for?

They are intended for fuel, oil, and water lines where an AN8 female connection must transition to a 3/8" hose. Typical uses include aftermarket fuel systems, oil coolers, remote filters, and custom plumbing on performance vehicles.

• Fuel-feed and return lines on modified engines.
• Oil cooler plumbing and remote filter hoses.
• Water or coolant bypass lines where AN8 fittings are present.

How do I install and secure the barb to prevent leaks?

Slide an appropriate 3/8" hose over the barb end fully, then use a quality hose clamp or crimp ferrule depending on hose type. Tighten the AN8 female mating end to the male fitting, then swivel the adapter into the final orientation before final clamp torque.

• Use fuel- or oil-rated hose sized to 3/8" (9.5mm) ID.
• Secure with a worm-drive clamp for street use or a crimp ferrule for performance reliability.
• Position swivel after hand-tightening the AN connection, then torque to spec.

Who is this for? These caqeg AN8-to-3/8" 90° swivel barb adapters suit automotive DIYers, fabricators, and motorsport technicians who need a compact, corrosion-resistant transition from AN8 threaded plumbing to standard hose. If you work on aftermarket fuel systems, oil cooler lines, or custom coolant routing and require a durable, lightweight elbow that can be precisely oriented, this Pack of 2 provides two reliable adapters to simplify installation and keep hoses clear of obstructions.
