What to consider before buying

When choosing a replacement connector hose, consider the material (brass vs. plastic), compatibility with your vehicle's cooling system, and the type of connection (straight, elbow, etc.). Brass connectors offer durability while plastic is more affordable. Always verify fitment with your vehicle's make and model.
