Metal Gasket H15
)
The H15 is available in various high-performance metallic materials, including chrome-molybdenum steels, austenitic stainless steels, and nickel-based alloys—offering excellent resistance to aggressive media. A version made from pure nickel is also available, providing a softer sealing material that can compensate for less-than-ideal flange surfaces and further reduce required bolt load.
A key feature of the H15A variant is its loose centering ring. In the rare event of a vibration-induced failure, especially in gas-tight systems, the centering ring is designed to fracture in a controlled manner and remain within the bolt circle—enhancing operational safety.
Furthermore, the contact diameter of the gasket can be flexibly adjusted, helping to avoid dead spaces and ensuring process cleanliness. While the H15 has no formal certifications or publicly available data sheet at present, sealing performance data according to EN 13555 is available.
