The ideal is no face-to-face contact, no gaps, and a metal touch.

The ideal of the HELICOFLEX seal is to achieve surface contact with no gaps, provide metal touch for seal protection, and satisfy the leak rate while preventing over-tightening.

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.

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.

"Selection of Metal Seals" <Materials Being Presented>

A high-performance seal manufacturer introduces important points for selecting metal seals such as spring-loaded C-rings.

A high-performance seal manufacturer of seal products such as spring-loaded C-rings, metal seals HELICOFLEXⓇ, and metal hollow O-rings introduces important points for making metal seals functional, as well as key considerations for designers. The selection of metal seals is crucially dependent on the design of the corresponding flanges. The materials 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. ★This document can be viewed immediately by clicking the download button. 【Contents (partial)】 ■ How to make metal seals functional? ■ Seal selection based on allowable leakage rate ■ Compression and recovery of metal seals ■ Bolt load and other factors *For more details, please download the PDF or feel free to contact us.

Metal seal adoption case: Chemical substance canister for semiconductor manufacturing

Good news for substances that cannot use resin or elastomer seal materials! By adopting metal seals, helium leak tightness has been achieved.

We would like to introduce a case where our "HELICOFLEX Delta Seal" was adopted for seals used in canisters by a chemical company. The specifications for the chemical company's canister seals required reliability to achieve helium leak tightness under both vacuum and positive pressure, as well as excellent durability, which ruled out the use of resin or elastomer materials. After adoption, helium leak tightness was achieved, and the design tightening pressure was lower than usual, resulting in reduced bolt load and a decrease in the number of bolts for the canister cover, which has limited space. 【Case Overview】 ■ Challenge - Desire to repeatedly transport chemicals with helium leak tightness ■ Results - Achieved helium leak tightness - Reduced bolt load due to lower design tightening pressure, leading to a decrease in the number of bolts for the canister cover - Also serves as a solution for PFAS measures *For more details, please refer to the PDF document or feel free to contact us.

Low design tightening pressure Y 'Ultra High Vacuum Delta Seal' for the semiconductor field

Delta Seal (HNV HELICOFLEX(R) DELTA) achieves ultra-high vacuum! [Standardized for JIS V-groove flanges]

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.
