Fujikin’s W-Seal interface offers superior performance where
reliability and safety are needed most in UHP process gas delivery
Made of 316L stainless steel, the W-Seal has a proven track record
of providing leak-free connections in weldless gas
lines in real-world applications.
very low torque is required to form a leak-free seal. Under test conditions,
we have 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 weldless
To further ensure the safety of these weldless 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
Only the W-Seal offers the robust performance, repeatability and proven
reliability making it the logical choice as an industry standard.

Fujikin’s 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.
