Euroseal® 2303 AOS Packing – Reliable Sealing Even at Extreme Temperatures
Euroseal® 2303 AOS packing is designed to ensure maximum reliability under extremely demanding operating conditions, such as high temperatures.
Made from braided filaments of Euroseal® Thermoseal — a highly resistant aluminum silicate — and Inconel, a high-performance metal alloy, this packing delivers a unique combination of mechanical strength, adaptability, and chemical stability.
The Thermoseal structure provides high dielectric rigidity, outstanding chemical stability, and exceptional resistance to high temperatures — up to 850°C in steam environments — without oxidation. The addition of Inconel wire ensures mechanical reinforcement, making this packing suitable for pressures up to 200 bar and intense thermal cycling, while maintaining its shape and sealing performance.
Thanks to its excellent adaptability to the stuffing box, Euroseal® 2303 AOS is ideal for control valves, especially where long-term performance is required in aggressive, corrosive, or abrasive environments. It offers full chemical compatibility across the entire pH range from 0 to 14. It is also the perfect solution for use as top and bottom rings in multi-ring configurations.
