Russell Performance 660683 AN Tube Sleeve Aluminum Hard Line Fitting

The Russell Performance 660683 is an AN tube sleeve fitting designed to connect steel or aluminum hard lines to standard 37-degree AN fittings. Russell tube sleeves are a core component of any hard line plumbing build, allowing fabricators to terminate rigid tubing directly to AN adapters, bulkheads, and system components without the need for a flexible hose assembly.

Key Features:

• Precision-machined aerospace-grade aluminum construction for strength and light weight
• 37-degree AN sealing angle for a leak-free, positive seal
• Compatible with standard steel or aluminum hard line tubing
• Available in anodized blue or Russell's Endura finish, which simulates the appearance of polished stainless steel
• Reusable design for long-term reliability
• Precision thread engagement for accurate, rattle-free installation

Russell tube sleeves are the ideal solution when a flexible hose assembly is impractical or prohibited by rulebook regulations. Engineered to meet the demands of performance, racing, and restoration applications, these fittings integrate seamlessly with the full Russell AN hard line system including tube nuts and adapter fittings.
