caqeg 6AN Female to 3/8" Push-Lock Hose Adapter — Straight & 90° Pack, Anodized 6061-T6, 1500 PSI

caqeg’s 6AN female straight and 6AN 90° to 3/8" push-lock barb fitting is a two-stage anodized aluminum adapter engineered to join 6AN-threaded components with 3/8" rubber fuel hose securely and without leaks.

This compact adapter combines a deep-threaded 6AN female port with a precision-machined barb to accept 3/8" rubber fuel line. Machined from 6061-T6 aluminum and finished with anodizing, it provides corrosion resistance and consistent dimensions for repeatable, tight assemblies in automotive fuel, oil, and performance plumbing projects. The package contains both a straight and a 90° variant so you can choose the routing that best fits your installation space.

How does this adapter create a leak-resistant connection?

The adapter relies on two complementary features to resist leaks: a full-depth 6AN female thread with a 37° internal chamfer and a barbed hose tail that grips rubber fuel line. Together they minimize gaps where fluid or dust could escape and make the joint robust against vibration.

• Deep, full-depth 9/16-18 UNF 6AN female threads for excellent mechanical engagement.
• 37° internal chamfer to ensure metal-to-metal seal where applicable and reduce visible gaps.
• Multi-ridge barb profile that holds rubber hose firmly when used with hose clamps.
• Anodized aluminum surface reduces corrosion that can compromise seals.

What materials and temperature/pressure limits should I expect?

The body is forged from 6061-T6 aluminum and anodized for colorfastness and surface protection. The adapter is rated for up to 1500 PSI and operates across a wide temperature range, making it suitable for typical automotive and marine fuel line conditions.

• 6061-T6 aluminum construction for strength with reduced weight.
• Anodized finish for wear and corrosion resistance.
• Working pressure: up to 1500 PSI; temperature range: -40°F to 248°F (-40°C to 120°C).
• Intended specifically for rubber fuel hoses (use clamps for best sealing).

Which fittings are included and how do I choose between straight and 90°?

This product includes two configurations: a straight 6AN female to 3/8" barb and a 90° 6AN female to 3/8" barb. Choose the straight piece when line runs are unobstructed and the 90° when you need to route hose around tight corners or avoid interference with other components.

• Straight adapter — ideal for inline connections and runs with room for hose routing.
• 90° adapter — reduces hose bending stress and clears nearby fittings or brackets.
• Hex-shaped outer profile accepts standard wrenches for tightening without marring the finish.
• Recommended to pair with quality stainless-steel clamps for long-term sealing.

How simple is installation and what tools or accessories are recommended?

Installation is straightforward for anyone familiar with AN fittings and rubber hoses. Thread the 6AN female end into the corresponding male 6AN component, then push the 3/8" rubber hose onto the barb and secure it with a clamp—no special crimp tools required for the barb end.

• Use a wrench on the hex flats to tighten the 6AN female end to spec; avoid over-torquing.
• Push the hose fully onto the barb until the last ridge is covered for best hold.
• Install a quality clamp (ear clamp, worm-drive, or crimp) over the barb for leakproof service.
• Inspect seals after first run and periodically for vibration-prone systems.

Who is this for: This caqeg adapter is aimed at mechanics, fabricators, hobbyists, and performance vehicle owners who need compact, reliable transitions between 6AN-threaded hardware and 3/8" rubber fuel hose. It suits retrofit jobs, custom fuel lines, turbine and pump hookups, and any application where a durable, anodized aluminum 6AN-to-barb transition will simplify hose routing and improve leak resistance.
