Russell Performance 767103 AN Tube Sleeves for Hard Line AN Fittings

Russell Performance tube sleeves are precision-engineered components designed to simplify the connection of aftermarket steel or aluminum hard line to factory hard lines using AN-style fittings. Whether you are building a custom fuel system, brake line, or oil line, Russell tube sleeves provide a secure, leak-free interface between your hard line and standard 37-degree AN fittings.

Key Features:

• Engineered to work with Russell tube nuts for a complete hard line AN connection
• Manufactured from aerospace-grade aluminum for strength and corrosion resistance
• Available with protective anodized or Endura finish for long-lasting durability
• Designed to seat and flare the hard line end securely against AN fitting threads
• Compatible with steel and aluminum hard lines
• Sold individually or as a pair depending on configuration

Russell tube sleeves must be used in conjunction with the corresponding Russell tube nut. Simply slide the tube nut onto the hard line first, followed by the tube sleeve, then thread the assembly onto any standard male AN fitting. The sleeve locks the hard line in place and prevents pull-out under pressure, making these an essential component for any serious performance plumbing build.
