20an Water Neck Adapter Fitting Female 90-Degree

The 20AN Water Neck Adapter Fitting Female 90-Degree is a crucial component for custom coolant routing in high-performance and modified engines. This fitting is ideal for builders working on street rods, race engines, or late-model platforms, allowing for efficient coolant flow redirection at a 90-degree angle to navigate around engine bay obstacles.

Manufactured to OEM-grade standards, this adapter is designed for compatibility with industry-standard braided stainless steel hoses and fittings. The 90-degree elbow geometry minimizes sharp bends in cooling hoses, which helps reduce turbulence and pressure drop while maintaining hose integrity during thermal cycling and vibration. Constructed from high-quality aluminum, it ensures durability and reliability in demanding automotive environments.

Engine builders and mechanics will find this adapter beneficial for designing custom water pump inlet/outlet configurations, block-mounted thermostat housings, or radiator hose runs on modified powerplants. Its compact footprint allows it to fit snugly in tight engine compartments, making it a versatile choice for various cooling system applications, including carbureted classics and EFI conversions.
