The Replacement O-Ring for Water Neck by ALLSTAR PERFORMANCE is an essential component for any engine cooling system overhaul or maintenance routine. This o-ring is designed to fit water neck fittings, which are critical junction points where the upper radiator hose connects to the engine block, preventing coolant leakage that can lead to overheating and engine damage.
Crafted from a durable elastomer compound, this o-ring is formulated to withstand exposure to hot coolant while maintaining sealing integrity across a wide temperature range. Its compact design—measuring 2 x 0.3 x 4 inches and weighing just 0.02 lbs—ensures a precise fit with OEM water neck assemblies, eliminating the risk of leaks that can occur with generic substitutes.
Ideal for mechanics and automotive enthusiasts, this replacement o-ring is perfect for those rebuilding cooling systems or performing routine maintenance. Its compatibility with ethylene glycol and extended-life coolants makes it a reliable choice for various applications, ensuring a leak-free seal at one of the most vulnerable points in your cooling circuit.
