They are an essential component for achieving leak-free connections in custom or factory-installed fuel, oil, or coolant lines. The 5/8 inch size makes them compatible with a wide range of aluminum hardline tubing systems, providing versatility and ease of installation. Each pack contains two inserts, offering a cost-effective solution for maintenance or build projects. Proper installation of these inserts helps prevent leaks, ensuring the integrity of your fluid transfer system and maintaining optimal performance of your vehicle.
