Armstrong Gaskets

Armstrong Gaskets – The gaskets which are using Armstrong materials are referred to as Armstrong gaskets. They include components made using fiber, rubber, cork, thermo-tork, NBR, sponge rubber among others which will vary as per industry requirements. We offer a variety of Armstrong Gaskets to fit the specific needs required in regard to temperature, pressure, and durability against the contents gaskets are exposed to.


Armstrong Gaskets Available:


STYLE 0782 Plant Fiber Rubber Beater Saturated (Armstrong CS-301)

Composed of cellulose fiber, cork, and styrene butadiene rubber (SBR). This fiber sheet is one of the most dependable in applications NOT involving aromatic fuels and solvents. The ability to swell moderately without decaying in water or oil is what makes this material special. Tensile strength minimum: 700 PSI. Temperatures to 300°F.


STYLE 0783 Plant Fiber Buna-N Beater Saturated (Armstrong CN-705)

Composed of cellulose fiber, cork, and Buna-N. Typically used in applications involving oil, gasoline, and water services. This material is powered by the combination of high compressibility and high crush strength. Tensile strength minimum: 1000 PSI. Temperatures to 300°F.


STYLE 0792 Cork and Neoprene Medium Hardness (Armstrong DC-i 00)

This neoprene rubber sheet contains very fine cork particles that creates a homogeneous material paired with the combination of excellent compressibility and the resiliency of neoprene. This material has high cork content and minimum side flow, making it applicable in general gasket and sealing purposes. This material is the solution for very narrow flange gaskets and for low-bolt load applications. Style 0792 is very useful for oil, non-aromatic petroleum derivatives, fatty oils, and solvents (except chlorinated, aromatic, or ketone types). Shore A Hardness 55-70. Temperatures to 275°F.


STYLE 0792A Cork and Neoprene Soft (Armstrong DC-i 79)

Same type material as Style 0792. The only difference is it is slightly softer, providing greater compressibility. Shore A Hardness 50-65.


STYLE 0793 Cork and Buna-N Medium Hardness (Armstrong NC-71 0)

This Buna-N sheet contains fine particles of cork. The added particles of cork creates a homogeneous material with excellent compressibility and optimal resiliency of Buna-N. This material is the solution for narrow flange gaskets and low-bolt load applications. This material is applicable for oil and non-aromatic petroleum derivatives. Shore A Hardness 55 to 70. Temperatures to 275°F.


STYLE 0793A Cork and Buna-N Soft (Armstrong NC-757)

Same type of material as Style 0793. The only difference is it's slightly softer, providing greater compressibility. Shore A Hardness 50-65.


STYLE 0793B Cork and Buna-N Firm (Armstrong NC-711)

Same type of material as Style 0793. The only difference is its firmness. Shore A Hardness 70-85.


STYLE 0794 Cork and Synthetic Sponge Rubber Adhesive Backed (Armstrong DK-1 53T)

This material is a unique blend of cork and sponge rubber that permits the combination of lasting resilience with high surface friction. It is commonly used to eliminate squeaks, cushion fragile parts, make slippery surfaces non-skid, or to absorb shock or relative motion between adjoining parts of an assembly. This material is known for the strength of its pressure-sensitive adhesive, which is protected with a polyethylene fiber.


STYLE 0794FC Cork and Synthetic Sponge Rubber Tape, Adhesive Backed (Armstrong DK-1 53T)

This material is the same as Style 0794. The lone difference is that it is in tape form, which is slit to your required widths.


STYLE 0N8051 Impervapac Nitrile Binder (Armstrong N-8051)

Recommended for applications involving low internal pressure and low flange pressure applications (Max. 2000 PSI). Moderate oil resistance. Nitrile Butadiene


STYLE 0N8090 Syntheseal Latent Cure Nitrite Binder (Armstrong N-8090)

Armstrong Syntheseal non-asbestos gasket materials have been formulated & designed to directly replace asbestos-containing materials. This specific material, Style 0N8090, is a reinforced cellulose fiber and a Latent Cured nitrile butadiene binder. The Armstrong Latent Cure System is designed for immediate conformity which allows users to seal rough flanges. As heat is introduced to the application, the ingredients are triggered which begins the vulcanization process of the material. This process provides the benefits of Fully Cured products. As a result, we are given a material with exceptional sealing characteristics. Supreme oil resistance. Temperatures below 350°F. Minimum tensile strength 2000 PSI.


STYLE 0N8092 Syntheseal Fully Cured Nitrile Binder (Armstrong N-8092)

Armstrong Syntheseal non-asbestos gasket materials have been formulated & designed to directly replace asbestos-containing materials. This specific material, Style 0N8092, is a reinforced cellulose fiber and a Fully Cured nitrile butadiene binder. This creates added value to the specialty of this material because the Armstrong Fully Cured system includes rubber binders that are vulcanized during formulation or in succeeding processes for amplified initial strength and fluid resistance. We recommend using Style 0N8092 for oils, fuels, and low pressure steam. Temperatures below 350°F. Minimum tensile strength: 1600 PSI.


STYLE 0S8091 Syntheseal Latent Cure Styrene Butadiene Binder (Armstrong S-8091)

Armstrong Syntheseal non-asbestos gasket materials are formulated and designed to be a direct replacement for asbestos-containing materials. This material, Style 0S8091, is special because it is a reinforced cellulose fiber with a Controlled Swell Latent Cure Styrene. These Armstrong Controlled Swell materials are Latent Cure products. These products use Styrene Butadiene Rubber (SBR) binders. The result is a significant increase in thickness at the exposed initial extremity of the gasket with many fluids, substantially enhancing sealability. As heat is introduced during application, the material is then vulcanized to limit further swelling and after fully cured performance. Use this material for oils, fuels, and low pressure steam. Temperatures below 350°F. Minimum tensile strength: 1800 PSI.


STYLE OTN9001 I Thermo-Tork Latent Cure Nitrile Butadiene Binder (Armstrong TN-9001)

Our Armstrong Thermo-Tork materials are non-asbestos formulated. This specific material has been developed to exceed the performance of many asbestos-containing products in a wide-range of heavy-duty applications. This material, Style 0TN9001, is aramid fiber with a Latent Cure Nitrile Butadiene binder. The Armstrong Latent Cure system is designed for immediate conformity which allows users to seal rough flanges. As heat is introduced during application, the ingredients are triggered which begins the vulcanization process of the material. This process provides the benefits of Fully Cured products. Style 0TN9001 is specifically designed for heavy-duty applications reaching temperatures up to 750°F. Supreme oil resistance. Minimum Tensile Strength 2000 PSI.


STYLE 0TS90131 Thermo-Tork Latent Cure Styrene Binder (Armstrong TS-9013)

Our Armstrong Thermo-Tork materials are non-asbestos formulated. This specific material has been developed to exceed the performance of many asbestos-containing products in a wide-range of heavy-duty applications. Style 0TS09131 is composed as a blend of cellulose & aramid fibers with a Latent Cure styrene binder. The Armstrong Latent Cure system is designed for immediate conformity, which allows users to seal rough flanges. As heat is introduced during application, the ingredients are triggered which initiates the vulcanization process of the material. This process provides the benefits of Fully Cured products. Style 0TS90131 has been developed for heavy-duty applications where temperatures reach up to 550°F. This material is recommended for water and oil applications. Minimum Tensile Strength is 1200 PSI.
