1.5in Water Neck - Low Profile 360 Deg. Swivel

The 1.5in Water Neck - Low Profile 360 Deg. Swivel by MEZIERE is a precision cooling system component engineered for high-performance engine builds where space and flexibility are critical. Whether you're running a custom carburetor setup, a fuel-injected stroker, or a radical street machine, this water neck adapter bridges the gap between your engine block's coolant port and your hose routing with minimal intrusion into the engine bay. Designed for builders and mechanics who demand compact, adaptable solutions, this swivel-style fitting eliminates hard-piping constraints and reduces the risk of coolant hose kinking in tight installations.

The 360-degree swivel design is the key to this fitting's versatility—it allows you to route your coolant hose in virtually any direction without compromising flow or requiring custom fabrication work. The low-profile casting minimizes overall height, critical when you're working with low-hood muscle cars, vintage hot rods, or modern performance vehicles where header clearance and intake manifold placement are tight. MEZIERE's precision machining ensures a leak-free seal at the 1.5-inch connection point, while the durable aluminum or ductile-iron construction handles both street-driven and track-use temperatures and pressures without degradation.

This water neck excels in engine conversions, custom cooling loop layouts, and builds where stock or traditional water necks won't fit. It's equally valuable for vintage engine swaps into modern chassis and modern engine installations into classic bodies, where plumbing geometry rarely aligns without creative solutions. Mechanics and enthusiasts benefit from faster assembly times and fewer custom hose orders; you can adjust hose run direction on the fly without removing fittings. The 0.86 lb weight adds negligible mass while delivering the flexibility that separates a professional, reliable build from one plagued by hose rerouting headaches and potential coolant leaks down the road.
