Series 600 Gasket Styles
Style 631—Two-Piece French-Type
Garlock Style 631 is
ideal for narrow circular
applications that require
a positive unbroken metal
gasket line across the
full width of the fange. The fller is exposed on the OD.
This gasket is also available in one, two, and three-piece
constructions.
Style 635—Selected Metal and CERAFELT®*
This gasket is de-
signed to be used in light-
weight fanges. The thick
compressible layer of
CERAFELT® is shielded
on the ID with a metallic barrier. Style 635 is commonly
used in applications with very hot gases and low pres-
sures.
Style 640—Solid Metal
This gasket offers ex-
tremely tight sealing, high
mechanical strength, and
good resistance to tem-
perature, corrosion and
pressure. Bolting stress and fange surface fnish are key
to the performance of this design.
Style 641—Solid Metal Profle
Profle gaskets com-
bine the desirable quali-
ties of a solid metal gasket
with the advantages of a
reduced area of contact,
thereby reducing the bolt
stress required to effect a seal. This gasket has the same
advantages of strength, heat conductivity, and resistance
to temperature, pressure and corrosion as Garlock Style
640.
Style 642—Grooved Metal
See Kammprofle, page D-17.
Styles 644 and 645—Single- and Double-
Jacketed Profle
Metal-jacketed profi le
gaskets employ the same
principle of reduced contact
area while protecting the
fange faces from damage due to scoring. This gasket
can be manu­factured in one of two designs—either single-
jacketed (Style 644) or double- jacketed (Style 645).
