Russell Performance 767083 AN Tube Sleeve Fitting

The Russell Performance 767083 is an AN tube sleeve designed to connect aftermarket or factory steel and aluminum hard lines to standard AN-style fittings. Tube sleeves are an essential component in any hardline plumbing installation, working in conjunction with a matching tube nut to create a secure, leak-free connection at the flared end of rigid tubing.

Key Features:

• Manufactured from lightweight aerospace-grade aluminum for strength and corrosion resistance
• Compatible with 37-degree AN flare fittings — the industry standard for performance plumbing
• Slip onto the hard line before flaring, then tighten with a matching tube nut for a positive seal
• Anodized finish provides protection against corrosion and a clean appearance
• Universal application — suitable for fuel, oil, brake, and other fluid systems
• Designed for use with Russell tube nuts for a complete, matched hardline connection

Russell Performance tube sleeves are trusted by racers and performance builders for their precision machining and consistent fit. When a flexible hose assembly is not practical or permitted, pairing a Russell tube sleeve with a tube nut and a 37° flaring tool delivers a professional-grade hardline connection.
