Russell Performance 767033 AN Hard-Line Tube Sleeve Fitting

The Russell Performance 767033 is an AN hard-line tube sleeve designed to connect steel or aluminum hard lines to 37-degree AN fittings. Russell Tube Sleeves are an essential component when a flexible hose assembly is not practical or when rules require hard-line plumbing — providing a clean, secure, and leak-free connection to AN adapters and fittings.

Key Features:

• Precision machined from aerospace-grade aluminum for lightweight, high-strength performance
• 37-degree AN sealing angle guarantees a positive, leak-free seal at maximum operating pressures
• Designed for use with steel or aluminum hard line tubing
• Must be used in conjunction with the matching Russell AN tube nut for proper installation
• Reusable design for long service life
• Compatible with fuel, oil, brake, and other fluid systems

Installation is straightforward: slip the tube nut onto the hard line first, then slide on the tube sleeve, and use a 37-degree flaring tool to flare the end of the tubing. When the tube nut is threaded onto a male AN fitting, the sleeve protects and supports the end of the hard line for a secure, professional connection.

Russell Performance has been a trusted name in advanced fluid transfer systems for over 30 years, manufacturing a complete line of hoses, fittings, and hard-line components for automotive, racing, and performance applications.
