Product Introduction

The 718 Metal Hollow O-Ring—a game-changing solution engineered to meet the rigorous demands of SOFC systems, with a leakage rate below  and unrivaled resistance to temperatures exceeding 500°C.

Why Choose Our 718 Metal Hollow O-Rings for SOFCs?

1、Ultra-Low Leakage PerformanceDesigned with precision

2、Exceptional High-Temperature ResistanceCrafted from premium 718 nickel-based alloy, our O-rings withstand continuous exposure to temperatures up to 550°C.

3、Versatility Across High-Performance Applications

While optimized for SOFCs, our 718 Metal Hollow O-Rings excel in other high-temperature, high-pressure scenarios, including:
Aerospace: Sealing in jet engines and rocket systems.
Automotive: High-performance exhaust and turbocharger systems.
Industrial: Petrochemical and power generation equipment.
