Series 600 Metal-Clad Gaskets
Gasket Styles
Style 600—Corrugated Solid Metal
A plain, all-metal
corrugated gasket for
use in low pressure ap-
plications that require a
thin line contact because of space or weight limitations.
Corrugated gaskets are a versatile sealing element where
the available bolt loads are low.
Style 606—Solid Metal with Flexible
Graphite Covering
A solid metal gasket covered with a layer of fexible
graphite. This cov-
ering layer seals at
a low load and flls
voids and imperfec-
tions in the fange.
Style 620—Single-Jacketed
Generally used where the radial dimensions of the
equipment sealing surfaces only allow space for a nar-
row width seal. Single-
jacketed gaskets are
constructed as shown
above. The metal jacket
reinforces the soft seal-
ing material.
Style 623—Double-Jacketed
The double-jacketed gasket has good compressibility
and resilience and is the most popular metal-clad gasket
manufactured.
Style 624—Single-Jacketed Overlap
Cons t ruc t i on of
this gasket offers more
fller protection than the
standard single-jack-
eted design. Although
constructed like a single-jacketed gasket, it has the added
beneft of totally encasing the fller material.
Style 626—Double-Jacketed Corrugated
Concentric corrugated sealing element totally
encapsulates the soft
fller material. The cor-
rugations give improved
resilience in applications
where thermocycling is a
problem.
Style 627—Double Shell
The double shell on this gasket allows greater hoop
strength and rigidity
with the addition of a
completely overlap-
ping inner seal. This
gasket will withstand
higher compressive loads common in high pressure ap-
plications.
Style 629—Double-Jacketed Corrugated
with Corrugated Metal Filler
The metal fller in Style 629 has greater resilience
to problems resulting from
thermocycling. The tem-
perature limits of this gas-
ket are governed only by
the metal selected.
