The encapsulated O rings are made of silicone rubber or fluororubber core and wrapped in an FEP or PFA outer shell. This combination of a rubber's flexibility with a PTFE (Teflon) resistance to chemicals makes for strong, long-lasting O-rings. Encapsulated O rings can handle extreme temperatures, chemicals, and wear and tear very well.

What are Spring Energized Seals
Posted in: Пружинные уплотнения
3020 Views
Spring Energized Seals are made up of U-shaped sealing rings made from PTFE and springs that resist corrosion. The metal spring provides the initial sealing force at low pressure and zero pressure. As system pressure rises, the sealing lip pushes out. It gently presses against the sealed surface. This keeps the sealing interface in contact, creating an excellent seal. It can be widely used in the chemical, pharmaceutical, and food industries.

What is a wear ring?
Posted in: Износостойкие кольца
2897 Views
Wear rings, or guide rings, sometimes referred to as wear bands, are an important part of hydraulic and pneumatic systems。 Wear rings play a critical role in hydraulic cylinders by absorbing side loads and preventing metal-to-metal contact between moving components. By guiding linear motion and minimizing friction, they improve system efficiency, reduce wear, and significantly extend equipment lifespan. The Guiding/Wear ring is a roll of tape. At XHH, we produce high-performance wear rings...
