A gasket sheet is a large piece of sheeting intended to be used in making gaskets, which ultimately assists in joining surfaces, or components, together for a tight seal.
Sheet materials are sold in a wide variety of material types and thicknesses, with the best choice for any given application being entirely dependent on the nature of the task the gasket will be performing. In this blog post, we’ll look at some of the different types of gasket sheet types and provide a high level overview of the best applicable uses.
All materials offered for fabricated gaskets can be purchased as whole or partial sheets from Gallagher Fluid Seals. All gasket sheet materials are in stock, and can be shipped within 24 hours.
The compressed, non-asbestos (CNA) gasketing line offers a variety of elastomers that provide exceptional sealability and excel in a wide range of services. The unique blend of aramid fibers, fillers and elastomeric binders provides improved torque retention and drastically lowered emissions levels
Garlock® GYLON® gasketing is a family of severe service PTFE gasketing materials manufactured using a proprietary process that imparts unique physical properties that are not obtainable through conventional manufacturing methods. ePTFE materials are made of 100% monoaxially expanded PTFE (ePTFE), using Gore’s expansion technology to create a high degree of fibrillation.
GFS Graphite materials, including Garlock Graph-Lock® and Klinger® Laminated Graphite, are composed of pure, exfoliated flake material. These materials excel in extreme conditions and withstands high temperatures, high pressures, and aggressive chemicals. Graphite materials also provide excellent resistance and is proven to be fire-safe.
High temperature gasketing excels in the harshest conditions—intense heat and high pressure. These high-performance gasket materials have been laboratory tested for fire safety. They maintain an effective seal during pressure and temperature fluctuations, and their excellent torque retention lowers leakage rates and reduces maintenance time.
Garlock® Inorganic Fiber Gasketing offers excellent thermal stability with minimal weight loss, reduced creep relaxation and improved torque retention. The inorganic fibers have excellent thermal and oxidation resistance, withstanding a continuous operating temperature of up to 550°F (290°C), and maximum spike of 800°F (425°C).
GFS offers sheet material in popular elastomeric materials. NBR, FKM, EPDM, Neoprene and Silicone, amongst others.
Compressed Non-Asbestos Sheet Material
The compressed, non-asbestos (CNA) gasketing line offers a variety of elastomers that provide exceptional sealability and excel in a wide range of services. The unique blend of aramid fibers, fillers and elastomeric binders provides improved torque retention and drastically lowered emissions levels. These materials offers cost savings by cutting operational costs through reduced waste, maintenance, stocked inventory, fluid loss, and energy consumption.
PTFE (Gylon/ePTFE) Sheet Material
Garlock® GYLON® gasketing is a family of severe service PTFE gasketing materials manufactured using a proprietary process that imparts unique physical properties that are not obtainable through conventional manufacturing methods. ePTFE materials are made of 100% monoaxially expanded PTFE (ePTFE), using Gore’s expansion technology to create a high degree of fibrillation.
Designed for severe chemical service, GYLON® gaskets are color-coded for easy identification and provide superior sealability to reduce process and media loss and fugitive emissions. They also reduce creep and cold flow characteristics.
GORE GR ePTFE is made of 100% monoaxially expanded PTFE (ePTFE), using Gore’s expansion technology to create a high degree of fibrillation.
Graphite Sheet Material
GFS Graphite materials, including Garlock Graph-Lock® and Klinger® Laminated Graphite, are composed of pure, exfoliated flake material. These materials excel in extreme conditions and withstands high temperatures, high pressures, and aggressive chemicals. Graphite materials also provide excellent resistance and is proven to be fire-safe.
High Temperature Sheet Material
GFS high temperature gasketing excels in the harshest conditions—intense heat and high pressure. These high performance gasket materials have been laboratory tested for fire safety. They maintain an effective seal during pressure and temperature fluctuations, and their excellent torque retention lowers leakage rates and reduces maintenance time. New Garlock THERMa-PUR® style gaskets provide extreme temp protection using a unique formulation with Garlock’s traditional quality.
Inorganic Sheet Materials
Inorganic Fiber Gasketing offers excellent thermal stability with minimal weight loss, reduced creep relaxation and improved torque retention. The inorganic fibers have excellent thermal and oxidation resistance, withstanding a continuous operating temperature of up to 550°F (290°C), and maximum spike of 800°F (425°C).
Elastomeric Sheet Material
GFS offers Elastomer Gasket Material in many of the most common elastomer materials. These include: Nitrile (NBR) Buna, EPDM, FKM (Viton), Neoprene (CR) and Red Rubber (SBR).
These materials are offered in various thicknesses, 1/8" and 1/16" are offered for sale below. Certifications such as FDA materials and various colors are part of the GFS material offering.
