Russell Performance 766043 -4 AN Black Anodized Aluminum Tube Sleeves 6-Pack

Russell Performance tube sleeves are precision-engineered components designed to connect aftermarket steel or aluminum hard line to AN-style fittings with ease and reliability. Part 766043 is a -4 AN tube sleeve sized for 1/4 in. O.D. hard line tubing and features a protective black anodized finish. Sold in a convenient 6-pack, these sleeves are an essential component for any hard line plumbing installation.

Key Features:

• AN Size: -4 AN (fits 1/4 in. O.D. tube)
• Finish: Black anodized aluminum for corrosion resistance and clean appearance
• Material: Lightweight aerospace-grade aluminum construction
• Quantity: 6 sleeves per package
• Style: Straight, reusable design
• Fitment: Universal application

Russell tube sleeves must be used in conjunction with a compatible tube nut. Slip the tube nut onto the hard line first, followed by the tube sleeve, then thread the tube nut onto the male AN fitting — the sleeve compresses to securely seal the end of the hard line. Ideal for fuel, oil, brake, and power steering plumbing applications where a rigid hard line connection is required.
