Overview
This D-shape retaining washer is engineered for high-integrity sealing in demanding flange connections. Its robust carbon steel construction provides a durable metal-to-metal seal capable of withstanding extreme pressures and temperatures common in critical industrial piping systems. The unique design incorporates both inner and outer reinforcing rings, which work in tandem to contain the sealing element, prevent buckling, and ensure precise, reliable alignment during installation. Each package contains 20 units, offering convenient inventory management for maintenance and project work.
Key Features
