Introducing C-rings for hydrogen leakage prevention in SOFC (Solid Oxide Fuel Cell) cell stacks.
"C-FLEX TM" is a C-ring with a unique C-shaped cross-section structure. It has a proven track record of solving hydrogen leakage in high-temperature cell stacks (750°C for 40,000 hours) and meeting low design tightening pressure requirements with the C-ring. Additionally, it is utilized in a wide range of applications, including crude oil extraction, industrial turbines, valves, aerospace, and automotive. 【Features】 ■ Unique C-shaped cross-section structure ■ Cross-sectional diameter and thickness designed considering compressive load ■ Compatible with internal pressure, external pressure, and axial direction ■ Low design tightening pressure ■ Pressure range: from medium vacuum to 200 MPa (2000 bar) ■ Temperature range: -273 to 730°C (-46 to 1350°F), with plating treatment for even higher temperatures ■ Structure that enhances sealing performance by providing auxiliary force from the operating pressure on the equipment side to the C-FLEX *For more details, please download the PDF or contact us.
