HelicoFlex series leak rate

Introducing the selection criteria for the HELICOFLEX(R) HN HelicoFlex series!

We would like to introduce the design standards for our HELICOFLEX(R) HN HelicoFlex series. Designed to meet two different leakage rates. Seal selection according to various applications (gas seals, liquid seals, toxicity, contamination, etc.) must be done before the detailed design of equipment and devices is completed. Insufficient bolt load will prevent even the best metal seals from meeting performance standards. We offer free bolt load calculations before estimates, so please feel free to contact us. 【Features】 ■ Leakage rate at a differential pressure of 1 bar is "bubble-tight" at 1×10^-5 Pa·m³/sec (10^-4 atm·cm³·sec) or below. ■ Leakage rate at a differential pressure of 1 bar is "helium-tight" at 1×10^-12 Pa·m³/sec (10^-9 atm·cm³·sec) or below. The quality of the installation side is crucial. (Seal performance depends not only on the seal itself but also on the material of the installation side, surface finish of contact surfaces, seal compression degree, pressure, temperature, etc. Additionally, it varies with seal shape.) *For more details, please refer to the PDF document or feel free to contact us.
