Front Plate Gasket WP150/WP155/WP350/WP355

The Front Plate Gasket WP150/WP155/WP350/WP355 is an essential component for serious engine builders and performance enthusiasts running Meziere water pump systems. Whether you're upgrading a street rod, rebuilding a classic, or fine-tuning a high-output engine, this gasket seals the critical interface between your pump's front cover plate and the engine block. Proper sealing at this junction prevents coolant weeping, maintains system pressure integrity, and ensures your cooling system operates at peak efficiency under demanding conditions.

Engineered by Meziere to OEM specifications, this gasket is manufactured from durable material designed to withstand thermal cycling and maintain a reliable seal across repeated heat-soak cycles. The gasket's compact profile—measuring 8 inches in length with a nominal thickness of 0.1 inches—allows for precise fitment without binding or interference with adjacent engine components. Its lightweight construction (0.01 lbs) means zero parasitic load while delivering the compression strength needed to prevent coolant bypass at the pump mounting surface, a common failure point in aggressive builds where standard gaskets fail under sustained pressure.

This gasket is compatible with Meziere WP150, WP155, WP350, and WP355 pump models, making it ideal for both small-block and big-block platforms across Chevrolet, Ford, Mopar, and universal applications. Mechanics and engine builders trust this OEM-equivalent component as a wear item during pump installation or rebuilds. Installation is straightforward: apply a light coat of gasket sealer to both sides, position the gasket carefully to avoid wrinkles, and torque fasteners in a star pattern to manufacturer specifications for a leak-free seal that lasts.
