is constructed exclusively of layers of GRAFOIL®
sheet made to virtually any desired thickness. These laminates are
easy to cut and are ideal where enhanced heat dissipation is a requirement.
When extra rigidity and tensile strength are required, GRAFOIL®
sheet is laminated with a variety of metal inserts to provide additional
mechanical strength and handling ease.
Both are available in style GTTM B, the standard industrial
grade, and GTTM A, which is designed for the stringent
requirements of the nuclear industry.
A special UCAR Carbon Company process introducing a non-metallic,
inorganic passivating inhibitor helps to produce two more grades
of corrosion and oxidation resistant GRAFOIL® grades
GTTM K for industrial applications, and GTTM
J for nuclear service.
LAMINATED SHEETS
-Density: 70 lb./ft.3 sheet used for all fabrications
-Nominal Thickness: 1/32", 1/16", 1/8", 1/4" and up
-Size: 24"x24", 39.4"x39.4" (MxM), 60"x60"
Custom sheet sizes, densities and
gauge thickness are readily available upon request. |

GRAFOIL® gaskets manufactured from
sheet or roll products will compact under only moderate bolt loads
to fill even microscopic irregularities in nearly every fluid sealing
application. Small surface irregularities are more easily filled under
lighter bolt loads, thus, reducing the need for costly surface refinishing.
Since there is negligible cold flow or creep, the need for periodic
precision bolt tightening is significantly reduced. |

RIBBON PACK™,
made from corrugated GRAFOIL® Flexible Graphite,
is a versatile product with universal application. It is designed
to provide the user with the flexibility to form all graphite endless
rings for any size pump or valve stuffing box.
GRAFOIL® Universal CRINKLE
GASKET TAPE can be used on the job site to form gaskets as
small as three inches in diameter. For large applications over eighteen
inches in diameter GRAFOIL®
PLAIN TAPE is available. Both are also ideal for emergency
repair or leaking flanges. |

Customizing ring density to maximize sealability is Sealing Devices Inc.'s specialty. All packing ring styles meet MIL-P-24503.
Fabricated from RIBBON PACKTM, GRAFOIL®
DIE-MOLDED PACKING RINGS are predensified for ease of installation.
They are precision sized to fit the dimension tolerances of valve
and pump stuffing boxes and require minimum run-in. GRAFOIL®
DIE-MOLDED RINGS create leak-tight seals with only 1/3 to 1/2
of the gland pressure required by other packings.
Grade GTTM K exhibits all
of the superior fluid sealing characteristics associated with
GRAFOIL® Flexible Graphite. It is the grade used
in most standard industrial applications. Grade GTTM
R is a premium grade developed for use in nuclear applications.
It is certified to meet the most rigorous purity specifications
of the nuclear industry, including General Electric NEDC-31735P.

LAMINATED RINGS are fabricated from sheet stock. The material is
cured to the desired thickness and density and then precision cut
to exacting dimensional tolerances. The process allows for custom
cross-sectional profiles where the application or design warrants
it. Laminated rings are available in all material styles.
