What is 6061 aluminum alloy?

6061 aluminum alloy is a common, well-built material known for its good strength, corrosion resistance, and weldability. It's a popular choice for many automotive and aerospace applications where a balance of performance and weight is needed.

What does '-3AN' refer to?

The '-3AN' designation refers to the size of the fitting. AN (Army-Navy) fittings are standardized for fluid transfer systems, and the number indicates the nominal tube outer diameter in sixteenths of an inch. So, -3AN corresponds to a 3/16-inch outer diameter.

What is the purpose of anodizing?

Anodizing is an electrochemical process that converts the metal surface into a durable, corrosion-resistant oxide finish. For these caps, the black anodized finish helps protect the aluminum from environmental factors and gives it a clean, finished look.

About this part

Product Details

Made from 6061 aluminum alloy, these -3AN flare caps from Vibrant are a solid choice for sealing off exposed ports on your fuel or oil lines. This material is chosen for its good strength-to-weight ratio, making it a practical option for fabrication work where every bit of weight can matter.

These caps are designed to thread directly onto your -3AN fittings, effectively blocking off any openings. This is crucial for preventing dirt, debris, or moisture from getting into your fluid systems, which could cause blockages or damage down the line. The black anodized finish not only looks sharp but also adds a layer of corrosion resistance.

If you're working on a custom fuel system, oil cooler setup, or any other fluid line application, having a few of these on hand is always a good idea for plugging off unused ports during assembly or testing.
