The use of the HELICOFLEX® DELTA seal in the vacuum-tight storage and transport of extremely toxic chemicals for semiconductor manufacturing is an ideal solution for transporting toxic chemicals involved in semis manufacturing. The seal is designed with two small ridges that create a highly contact stress in the seal track, making it suitable for ultra-high vacuum applications with low Helium leak rates and passing qualification tests in 2000. The HELICOFLEX® DELTA is an ideal solution for this particular application and has been used to supply thousands of precision metal seals annually.
