Section diameter and wall thickness considering design tightening pressure! We offer basic shapes and high-pressure balance types.

"O-FLEX TM" is a metal O-ring with a cross-sectional diameter and wall thickness that takes into account the design tightening pressure (Y value). It can be manufactured for both internal and external pressure, and rectangular shapes are also available. The pressure range is from high vacuum to 500 bar (7,252 PSI), and the temperature range is from -273 to 650°C (-460 to 1200°F). 【Features】 ■ Cross-sectional diameter and wall thickness considering the design tightening pressure (Y value) ■ Can be manufactured for both internal and external pressure ■ Basic type and high-pressure balanced type ■ Rectangular shapes are also available *For more details, please refer to the PDF materials or feel free to contact us.

News about this product(1)

Here are some important points to consider when selecting metal seals such as spring-energized C-rings! <Materials available upon request>

  • Catalog news

We will introduce important points for making metal seals functional, as well as key considerations for designers, from a high-performance seal manufacturer of products such as spring-energized C-rings, metal seals like HELICOFLEXⓇ, and metal hollow O-rings. The selection of metal seals is crucially dependent on the design of the corresponding flanges. Factors such as the material of the flanges and bolts, the tightening load (minimum required bolt load during tightening), pressure, temperature, and the method of bolt fastening are all related to the occurrence of insufficient compression in metal seals. *For more detailed information, please download from the related catalog.
