Overview
This D-ring metallic wound gasket is engineered for creating high-integrity, leak-tight seals in standard flanged piping connections. It is constructed with a resilient graphite filler wound between concentric layers of stainless steel, reinforced with solid inner and outer retaining rings. This design provides exceptional sealing force distribution and compensates for flange face irregularities, making it suitable for a wide range of demanding industrial services involving elevated pressures, temperatures, and aggressive media. The gasket conforms to recognized industry dimensional and material specifications, ensuring reliable interchangeability and performance in critical applications.
Key Features
