O-ring seal HELICOFLEX® TEXEAL®

circularmetalfor aircraft

Increase the overall sealing performance for your installations with TEXEAL®, the new patented texturing process, applied to HELICOFLEX®, already the resilient metal seal standard for high-performance sealing. HELICOFLEX® TEXEAL® can help reduce operating costs during maintenance. It is a material innovation developed from decades of established sealing expertise. FEATURES & BENEFITS Decreased overall cost of assembly during design phase Reduced overall operating cost MTBF (mean time before failure) increase LCC (life cycle cost) ​decrease Sealing performance optimized without increasing tightening force​ (up to 10-12 Pa.m3.s-1) Lower stress on the assembly using the same tightness level Sealing performance maintained during thermal cycles Adaptable to a wide range of assembly dimensions Adaptable to groove sealing surfaces Choice of Materials PRODUCT APPLICATIONS Nuclear: reactor pressure vessels closure head, control rods, reactor coolant pumps (RCP), pressurizers, steam generator, spent fuel casks New energies: molten salts & solar plants Semiconductor: chamber, exhaust and other applications in PVD/CVD/etch and lithography processes Valves: body/bonnet sealing, seat sealing Steam generator seal
