[Standardized for JIS V Groove Flange] Low Tightening Pressure Y 'Ultra High Vacuum Delta Seal' for Semiconductor Field
Technetics Group Japan
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 the flange groove is assembled. The design tightening pressure of the Delta Seal is lower compared to the Helicoflex seal, allowing for replacement with elastomer O-rings. Leak rate: *For circular shapes, 10⁻¹² Pa·m³/sec. (10⁻¹¹ atm·cm³/sec.) *Depends on the quality of the installation side. 【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.
