It has a lower design tightening pressure compared to standard helicoflex seals and copper gaskets for ICF flanges. It demonstrates its capabilities on a smooth sealing contact surface, achieving a higher level of ultra-high vacuum compared to other seals. Additionally, standard drawings for Delta seals for JIS B2290 V-grooves are available. 【Product Lineup】 ■ Delta Seal (HNV HELICOFLEX DELTA) ■ Metal Hollow O-Ring (O-FLEX) ■ Quick Disconnect System (QDS) ■ HelicoFlex Seals (HN, HELICOFLEX) ■ Metal C-Ring (C-FLEX) *For more details, please refer to the PDF materials or feel free to contact us.

The "HELICOFLEX(R) Seal" is an elastic metal seal developed in collaboration with the French Atomic Energy Commission (CEA). The ideal state is a strong mechanical clamping condition known as "metal touch." It seals while protecting the Helicoflex seal and preventing over-tightening. Metal touch offers advantages such as reliable compression, minimal seal elastic deformation, and maintenance of flange rigidity. 【Features】 ■ Reliable compression ■ Minimal seal elastic deformation ■ Maintenance of flange rigidity ■ Resistant to temperature changes *For more details, please refer to the PDF document or feel free to contact us.

Our HELICOFLEX(R) spring-energized C-ring metal seals are designed for advanced sealing in critical applications. We offer structures beyond the standard, such as the "HL," which is equipped with an internal limiter to prevent over-tightening, and the "HNR," which features specially processed springs to achieve low design tightening pressure. These seals are used in harsh environments, including accelerators, aerospace, fusion reactors, nuclear power plants, cryogenics, and semiconductor manufacturing equipment. 【Features】 ■ HLO: Can be used as a substitute for ring joint gaskets ■ HL: Equipped with an internal limiter to prevent over-tightening ■ HNR: A type with specially processed springs to achieve low design tightening pressure ■ HNV: Keeps initial seal levels and design tightening pressure low *For more details, please refer to the PDF document or feel free to contact us.

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.

We would like to introduce the compression and recovery characteristics of our HELICOFLEX® series. The compression recovery of the HELICOFLEX series features a gently flattening compression curve. The recovery curve takes a different shape than the compression curve. This is the result of two permanent deformations (the elastic deformation of the spring and the plastic deformation of the outer casing). Each value is determined by the allowable leakage amount and the selection of materials. We have included a diagram with detailed information in the catalog, so please feel free to download and take a look. *For more details, please refer to the PDF materials or feel free to contact us.

The "HelicoFlex Seal" is an elastic metal seal developed in collaboration with the French Atomic Energy Commission (CEA). The bolt load for the HelicoFlex series is determined according to CODAP (Annex C6A4: analogous to the "Bolt Tightening Flange Regulations for Pressure Vessels" such as JIS). At the quotation stage, we will also provide a technical data sheet (TDS) with dimensions of grooves, etc., and perform calculations for bolt load and tightening torque, so please feel free to inquire. *For more details, please refer to the PDF materials or feel free to contact us.

The Delta Seal (HNV HELICOFLEX(R) DELTA) has two delta-shaped protrusions on the contact side of the cross-section. The delta-shaped protrusions are designed to collapse and disappear during the compression of the outer casing when integrated into the flange groove, and the design tightening pressure of the Delta Seal is lower compared to the Helicoflex seal, allowing for replacement with elastomer O-rings. Leakage rate: *For circular shapes, 10⁻¹² Pa·m³/sec. (10⁻¹¹ atm·cm³/sec.) *Depends on the quality of the installation side. Also varies depending on the seal shape. 【Features】 ■Two delta-shaped protrusions on the contact side of the cross-section ■Achieves ultra-high vacuum ■Has excellent elasticity and can be used at high temperatures ■Can be replaced with elastomer O-rings *For more details, please refer to the PDF document or feel free to contact us.

The spring of the "HelicoFlex Beta HNR" has been specially processed around its entire circumference to distribute elasticity more appropriately to the metal casing. When compared to the standard HelicoFlex seal, the design tightening pressure (Y2 value) is theoretically reduced by about 30%. As a result, there are more cases where metal touch can be achieved without scratching the flange groove. For more details, please contact us. 【Features】 ■ Special processing applied around the entire circumference ■ Even lower design tightening pressure than before ■ Maintains functionality even under positive pressure and high temperatures *For more information, please refer to the PDF document or feel free to contact us.

The "Omicron Seal HLO" is designed for ring joint grooves and utilizes an internal limiter spacer.
