Fujikin's innovative new W-Seal
Interface offers superior performance where reliability and safety
are needed most in ultra high purity process gas delivery systems.
Constructed with 316L stainless steel, the W-Seal has a proven track
record of providing leak-free connections in weld-less gas lines in
demanding real-world applications.
Only the W-Seal offers the robust performance, repeatability and proven
reliability making it the logical choice as an industry standard.
The unique W-Seal is the industry's most reliable 100-percent
top-mounting seal, providing a greatly reduced number of sealing points
and utilizing only one W-Seal gasket required per valve. The W-Seal
also is highly configurable to support a wide range of semiconductor
fab equipment requirements.
Fujikin's innovative base-block design allows top access to
all components and substrates. Clamping tools and through-bolts are
not required to assemble an Integrated Gas System (IGS) based on this
design so maintenance time is greatly reduced.
The number of sealing points is lowered by utilizing a V-shaped flow
path through the substrate. Components can be easily removed and repositioned
as system layouts are altered. While other substrate manufacturers
require several types of gaskets for component or side mount connections,
the Fujikin design uses only one type of W-Seal gasket, thus simplifying
assembly and maintenance, and reducing inventory.
With the W-Seal, a very low torque is required to form a leak-free
seal. Under test conditions, Fujikin has achieved a leak rate of 2.9
x 10^15 Acc/sec. This level of reliability is required as the industry
moves from welded to weld-less gas systems.
To further ensure the safety of these weld-less systems, the W-Seal
gasket now comes with a Guide Ring. This device adds an additional
level of protection against scratches to the sealing surface of the
