AN Male to Male Flare Coupler 8AN to 6AN Straight Aluminum EVIL ENERGY

Description

Product Overview

The EVIL ENERGY AN male‑to‑male flare coupler is engineered for professional and enthusiast automotive applications where a secure, high‑performance fuel line connection is essential. Constructed from aerospace‑grade 6061‑T6 aluminum alloy, the coupler offers a lightweight yet exceptionally durable solution that resists corrosion, fatigue, and the harsh chemicals found in gasoline and diesel environments. The straight‑through design provides a direct flow path, minimizing pressure drop and ensuring consistent fuel delivery. Thread specifications are 9/16‑18 UNF for the 6AN side and 3/4‑16 UNF for the 8AN side, delivering a precise, leak‑free seal when paired with compatible flare fittings. The coupler is rated for a maximum working pressure of 1,500 psi and can operate safely across a temperature range of –40°F to 250°F, making it suitable for a wide variety of climates and performance demands.

Usage

This flare coupler excels in fuel system installations where reliability and ease of service are paramount. Typical use cases include extending fuel hoses, connecting fuel lines to filters, fuel pumps, and cooler systems, as well as retrofitting older vehicles with upgraded components. The straight configuration is ideal for applications that require a direct line without the added complexity of angled bends, reducing the risk of turbulence and wear. Installers appreciate the intuitive UNF threading, which aligns perfectly with standard AN fittings, allowing for quick assembly with common hand tools. Whether you are building a high‑performance race car, restoring a classic vehicle, or performing routine maintenance on a daily driver, this coupler delivers the confidence of a leak‑free connection.

FAQ

What types of fuel systems can I use this coupler with?

The coupler is compatible with gasoline, diesel, and ethanol‑blended fuel systems. It is commonly used to connect fuel hoses, filters, pumps, and cooler lines in both performance and street‑driven vehicles.

Do I need any special tools to install the coupler?

No special tools are required. A standard flare nut wrench or a set of open‑ended wrenches that fit the UNF thread sizes will allow you to tighten the coupler securely. Always follow torque specifications provided in your vehicle’s service manual.

Can I use this coupler in high‑performance racing applications?

Yes. The aluminum alloy’s high strength‑to‑weight ratio, combined with its 1,500 psi pressure rating, makes it well‑suited for racing environments where weight savings and reliability are critical.

Is the coupler compatible with angled fittings?

The standard model is a straight‑through design, but EVIL ENERGY offers angled versions (45° and 90°) in the same material and pressure specifications for applications that require directional changes.
