What size hose does this waterneck fit?

This Edelbrock waterneck is designed to fit any 1-1/2 inch diameter outlet hose. This is a common size for many V8 and V6 engine applications.

Why is the two-piece design with an O-ring seal beneficial?

The two-piece design with an O-ring seal creates a reliable seal against the intake manifold. It also allows you to remove the waterneck for maintenance or service without needing to replace the gasket, saving you time and hassle.

Can I rotate the hose outlet on this waterneck?

Yes, this waterneck features a 90-degree adjustable swivel outlet. This allows you to position the hose outlet in the direction that best suits your plumbing setup, which is particularly helpful in custom engine builds or tight engine compartments.
