BBC Water Pump Port Adapters - Black (2pk)

The MEZIERE BBC Water Pump Port Adapters in black anodized aluminum deliver a reliable solution for converting standard water pump ports to remote-mounted configurations on big block Chevy engines. This 2-pack of adapters features 3/4-inch NPT female ports with O-ring seals, ensuring leak-free connections for custom cooling system layouts. Built from aluminum and finished in black anodized coating, these adapters provide the corrosion resistance and durability required for high-performance engine builds.

Each adapter in this water pump adapter pair maintains the 3/4-inch NPT female port standard, allowing direct compatibility with common hose fittings and remote water pump setups. The O-ring seal design eliminates the need for thread sealant tape, reducing installation time while preventing coolant weeping at connection points—a critical advantage in tight engine bays where access for maintenance is limited. The aluminum construction keeps weight minimal compared to brass alternatives, while black anodized finishing resists oxidation in both street and race environments.

These adapters serve builders transitioning from factory-mounted water pumps to remote mounting systems, whether for engine bay thermal management, electric cooling fan integration, or race-oriented plumbing configurations. The two-piece set accommodates dual inlet and outlet connections or provides a spare adapter for redundancy. MEZIERE's adapter solution is engineered for BBC engine swaps and vintage performance builds where custom cooling layouts require standardized port conversion. Weighing just 0.49 lbs for the pair, installation is straightforward with standard NPT wrenches.
