The ALLSTAR PERFORMANCE Tube Sleeves Aluminum 4AN 2-pack (SKU ALL 50331) provides reliable AN fitting protection for 1/4-inch tubing in high-performance fuel, coolant, and hydraulic applications. These black anodized aluminum sleeves are engineered to secure and protect tube connections in racing engines, custom automotive builds, and industrial systems where precision plumbing meets demanding operating conditions.
Each 4AN tube sleeve in this two-pack is sized for 1/4-inch tubing and manufactured from anodized aluminum, delivering corrosion resistance and durability in engine bays exposed to heat cycles, fuel exposure, and vibration. The black anodized finish provides both aesthetic consistency with other fuel system components and a protective barrier against oxidation. The pair format makes it cost-effective to outfit multiple connection points or maintain spares in your racing or shop inventory.
These sleeves are essential for builders assembling custom fuel systems, cooling circuits, and hydraulic setups using AN-standard fittings. Whether you're configuring a street rod fuel delivery system, a circle-track racing engine, or a high-performance marine cooling application, proper tube sleeves prevent leaks, reduce fitting stress, and ensure long-term system reliability. ALLSTAR PERFORMANCE tube sleeves are trusted components in the hot rod, racing, and custom automotive communities where system integrity cannot be compromised.
