Vibrant Female AN Plastic Plug AN -3

This is a Vibrant Performance Female AN Plastic Plug, specifically for AN -3 size fittings. It's a simple but important part for anyone working with AN lines, whether you're building a custom fuel system, a brake line setup, or any other fluid transfer application. Its main job is to keep dirt, dust, and other contaminants from getting into your hoses and fittings when they're not connected or when the system is temporarily out of service.

Made from durable red plastic, this plug is designed to fit securely into any 37-degree AN flare fitting or straight-cut AN port of the corresponding size. It's a well-built little piece that makes a big difference in keeping your fluid systems clean and preventing potential issues down the road. Think of it like putting a cap on a bottle – it just keeps things tidy and protected.

You get a pack of five of these plugs, which is handy because you'll likely need them for multiple lines or have spares on hand. They're a straightforward, effective way to protect your investment in custom plumbing.
