## Description

This straight swivel hose adapter converts an AN6 female fitting to a 3/8 inch barb for 9.5 mm hose, offering a compact link between threaded fuel lines and flexible tubing. It is intended for automotive fluid systems and helps route fuel, oil, or water lines where a secure barb connection is required.

## Key Points

The adapter comes as a pack of two, which is useful when you need matching fittings for both ends of a run or for parallel lines. The straight swivel design allows the threaded side to be tightened independently of the hose barb, reducing stress on the hose during installation and alignment. According to the manufacturer, these fittings are compatible with gasoline and alcohol-based fuels, so they can be used in many performance and maintenance applications. ⚙️

Corrosion resistance is a priority for exposed fittings, and the anodized surface improves durability in workshop conditions. The lightweight billet construction helps minimize added weight compared with heavier brass alternatives. Keep in mind that these fittings are intended for typical automotive fuel and coolant circuits and may not be rated for very high pressure or extreme temperature systems.

## Technical Specifications

- Name: **caqeg 6AN Female to 3/8 Barb Hose Fitting Adapter Straight Swivel, Pack of 2**
- Material: 6061-T6 aluminum
- Hose inner diameter: 9.5 mm (3/8 inch)
- Thread: AN6 female (9/16-18 UNF)
- Finish: anodized, black

## Usage Recommendations

Use a compatible nylon or reinforced rubber hose sized to the specified 9.5 mm inner diameter to achieve a reliable seal on the barb. For best results, slide the hose fully over the barb and secure it with a proper clamp sized for automotive fuel lines. When tightening the AN6 female thread, hold the swivel stationary to avoid twisting the hose. For alcohol-blended fuels, inspect seals and hose materials periodically for signs of degradation according to usage intervals you normally follow. 🛠️

Consider that push-on or soft hoses can slip if not clamped correctly, so verify clamp placement after initial runs. Also, while anodizing increases corrosion resistance, check fittings periodically in harsh environments and replace if you detect pitting or wear. 🚗
