It is a metal O-ring with a coil spring as the elastic element, covered with a thin metal plate such as aluminum.
Compared to general metal gaskets, it has a larger recovery amount and can be used under low tightening forces, while retaining the advantages of metal gaskets, making it applicable over a wide temperature range from extremely low to high temperatures. In particular, rubber O-rings and metal hollow O-rings maintain a high vacuum seal over a wide temperature range even in ultra-high vacuum areas where performance issues may arise.

basic information
【Features】 ○ Excellent compatibility and outstanding vacuum sealing performance. ○ Superior vacuum sealing performance during restoration. ○ Applicable across a wide temperature range from extremely low to high temperatures. ○ Can be used in vacuum lines where O-rings cannot be used due to high baking temperatures. ○ As a metal gasket, it is largely unaffected by radiation-induced degradation or gas emissions. ○ Ideal for aluminumizing lines to accommodate induced radiation, low temperatures, and gas emissions. Moreover, it does not leave pressure marks on the flange surface due to gasket tightening. ○ The coil spring is welded only at the wire end face by upset welding, ensuring complete structural and stress continuity. (PAT.) (However, coil springs with a cross-sectional diameter of φ1.7 will be butt-welded.) ○ Custom shapes can be manufactured. ● For more details, please contact us or download the catalog.
