HPS Performance Products AN818-12 Aluminum Tube Nut for AN-12 Hard Line

The HPS Performance Products AN818-12 is a precision-engineered aluminum tube nut designed for AN-12 hard line applications. This essential fitting component allows you to build custom hard line plumbing systems as a durable alternative to flexible braided hoses in high-performance automotive, racing, and motorsports applications.

Key Features:

• Constructed from high-quality 6061-T6 aluminum alloy for excellent strength-to-weight ratio
• Type II black anodized finish provides superior corrosion resistance and professional appearance
• AN-12 size compatible with standard AN-12 hard line tubing
• Suitable for use with fuel, oil, coolant, alcohol, nitrous oxide, and hydraulic fluid systems
• Must be used with corresponding AN819-12 tube sleeve (sold separately)
• Meets AN (Army-Navy) military specifications for precision and reliability

This tube nut threads onto AN-12 hard line tubing and compresses the tube sleeve to create a secure, leak-free connection. The lightweight aluminum construction and corrosion-resistant anodizing make it ideal for professional race vehicles, street performance builds, and custom plumbing installations. Note that tubing and tube sleeve are not included and must be purchased separately.
