C-shaped cross-section low tightening pressure metal seal C-ring 'C-FLEX TM'
We introduce C-rings with sections and thicknesses that take into account compressive loads.
The sealing concept of "C-FLEX TM" is the elastic deformation of a metal seal with a C-shaped cross-section. It is compensated by the internal pressure of the equipment to accommodate low design tightening pressure and uneven surfaces of the flange. It is utilized in a wide range of applications, including crude oil extraction, industrial turbines, valves, aerospace, automotive, and SOFC fuel cells (750°C for 40,000 hours). 【Features】 ■ Unique C-shaped cross-section structure ■ Cross-sectional diameter and thickness designed for low tightening pressure ■ 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) ■ The structure enhances sealing performance by providing auxiliary force from the operating pressure on the equipment side to the C-FLEX. *For more details, please refer to the PDF document or feel free to contact us.
