Metal Bonded Rubber Seal Manufacturer | RUBBER-STEEL FLANGE GASKETS

Premium Rubber-Steel Gaskets (G-ST)

Our rubber-steel gasket consists of a rigid steel ring in the core, ensuring optimal surface pressure absorption and supporting the safe centering of the gasket within the flange. Manufactured to strictly comply with DIN EN 1514-1 (PN6-40), the steel support ring actively prevents gasket blow-out and increases overall stability. Meanwhile, the specialized rubber sealing material perfectly adapts to sealing surfaces to create a secure, leak-proof connection.

✔ Anti-Blowout Steel Core

✔ DIN EN 1514-1 (PN6-40)

✔ High Surface Pressure Absorption

✔ Superior Centering & Stability

Wide Range of Applications

Rubber-steel gaskets have a wide range of applications in advanced sealing technology, including:

• Drinking water supply & Wastewater systems

• Pipeline construction with vacuum-operated pipelines

• Chemical industries (aggressive media, acids, and alkalis)

• Pipeline systems with all-rubber flange sealing surfaces

• Gas, flue gas cleaning systems & power plant cooling circuits

Comprehensive International Certifications

The true strength of Haiyixin Rubber seals lies in the numerous rigorous certifications we have been awarded. Our materials are fully validated for safety and performance in both potable water and demanding gas applications.
