Product Details

The NOS 17551NOS is a precision-engineered tube nut designed for secure connections in nitrous oxide plumbing systems. This component features a red anodized aluminum finish that provides both corrosion resistance and a distinctive appearance under the hood.

Key Features:

  • -3AN male flare connection for compatibility with AN fittings
  • Fits 3/16" O.D. hardline tubing
  • Lightweight anodized aluminum construction
  • Red anodized finish for corrosion protection and custom appearance
  • 37° AN flare sealing surface for leak-free performance
  • Designed for use with matching tube sleeve (sold separately)

This tube nut is an essential component for building professional-grade nitrous oxide systems, fuel lines, and other high-performance plumbing applications. The -3AN thread size is a common standard in performance automotive applications, ensuring compatibility with a wide range of hoses, fittings, and components. NOS uses proper 37° AN fittings throughout their product line to ensure reliable, leak-free connections when properly installed with the correct tube sleeve.

Note: This product is intended for racing use only vehicles that are used exclusively for competition and are not registered for street use.
