Product Introduction
Encapsulated silicone‑rubber O‑rings are composite industrial sealing parts with dual‑layer construction. Manufactured by special thermo‑compound encapsulating process, they adopt elastic silicone or FKM rubber as inner core, seamlessly wrapped with FEP or PFA fluoroplastic outer jacket. This design combines high elastic resilience from rubber core and outstanding chemical inertness of fluoropolymer shell. Core strengths include superior corrosion‑resistance against most acids, alkalis and solvents, ultra‑low friction, broad temperature adaptability and anti‑swelling performance. It delivers stable static and low‑speed dynamic sealing under harsh corrosive working conditions, preventing medium leakage and core material erosion. Widely used for chemical valves, pumps, filter equipment, pharmaceutical processing and food‑industrial facilities. Standard sizes complying with AS568 and DIN specs are in stock. Custom dimensions, inner‑core materials and food‑grade grades are supported according to drawings or samples for complex sealing demands.
