Russell Performance 767123 AN Hard-Line Tube Sleeves

Russell Performance tube sleeves are precision-engineered AN hard-line fittings designed to securely attach steel or aluminum tubing to 37-degree AN fittings. Whether you're building a custom brake line, fuel line, or oil system, these tube sleeves deliver a leak-free, positive seal in demanding performance applications.

Key Features:

• Precision-machined aerospace aluminum construction for lightweight strength
• 37-degree AN sealing angle provides a reliable, positive seal
• Compatible with both steel and aluminum hard-line tubing
• Available in protective anodized blue, black anodized, or Endura finish (simulates stainless steel appearance)
• Must be used in conjunction with the corresponding Russell AN tube nut
• Universal fitment — ideal for race, street, and off-road plumbing applications

Russell tube sleeves are the go-to choice when a flexible hose assembly isn't practical or permitted by sanctioning body rules. Simply slip the tube nut onto the hard line first, followed by the tube sleeve, then thread onto the male AN fitting for a secure, professional connection.
