Water Jacket Adapter Fit ting for Garret BB Turbo

The Water Jacket Adapter Fitting for Garrett BB Turbo is a precision engineered cooling system component designed for high-performance turbocharger installations. This adapter serves as the critical bridge between your turbocharger's water jacket and your vehicle's cooling circuit, ensuring proper coolant flow and thermal management under boost. Built by VIBRANT PERFORMANCE, this fitting is engineered for reliability in demanding applications where turbo heat rejection directly impacts engine longevity and performance consistency.

This water jacket adapter features a straight-flow design with 6 AN male port connections and an 18 mm x 1.50 male thread interface, allowing seamless integration with both hose barbed fittings and threaded coolant lines. Constructed from aerospace-grade aluminum and finished in durable black anodized coating, the adapter resists corrosion while maintaining lightweight properties critical for engine bay applications. The anodized surface provides both aesthetic integration and superior protection against coolant-induced oxidation, extending service life in high-heat turbo environments where standard finishes fail prematurely.

Turbocharger enthusiasts and performance builders rely on this adapter to establish redundant coolant pathways, preventing hot spots that lead to bearing wear and premature turbo failure. Installation pairs perfectly with custom coolant line routing systems and aftermarket turbo manifold combinations where OEM fittings prove incompatible. The compact 3.35 x 1.05 x 3.55 inch profile fits tight engine bays, while the 6 AN porting accommodates standard braided stainless hose assemblies found in most performance cooling upgrades.
