Gasket Materials​
Flexible Graphite Sheets
Our Style 7000 flexible graphite sheets deliver a reliable, tight seal even after repeated exposure to extreme environments. Key advantages include exceptional resistance to heat, fire, corrosion, and aggressive chemicals, making flexible graphite one of the most versatile sealing solutions available today. It excels in applications where other materials fall short, sealing effectively under moderate bolt loads while minimizing damage during handling and installation.​

NSF-61 Approved Products:
Select materials are certified to NSF/ANSI Standard 61 for Drinking Water System Components. This standard ensures that products in contact with potable water meet strict limits for potential contaminants, providing safety and compliance.​FDA Compliant Products. Certain grades are developed for food and dairy applications, offering high-performance seals with superior mechanical strength and chemical resistance. These comply with Food and Drug Administration requirements to ensure safety, wholesomeness, and sanitary conditions in food-related uses​.
​
EPDM
EPDM (ethylene propylene diene monomer) is a highly durable synthetic rubber classified as an M-class elastomer under ASTM D-1418, as well as SAE J200 and ASTM D2000 standards. EPDM gaskets provide long-lasting sealing across extreme weather conditions and wide temperature ranges. They offer outstanding resistance to aging, wear, wind, ozone, and UV light compared to many other rubbers. Additional benefits include color stability (no staining of mating surfaces) and good electrical insulation properties. However, EPDM is not recommended for exposure to oils, gasoline, halogenated solvents, or concentrated acids.
Buna-N / NBR
Buna-N (nitrile butadiene rubber) gaskets are widely used and cost-effective, available in commercial, premium, military, and FDA-compliant grades. Enhancing NBR through compounding with PVC or specific curing methods (sulfur or peroxide) improves its properties for demanding industrial applications.​
​
PTFE (Teflon®) Sheets Black or White
Our Style 7530 virgin PTFE (polytetrafluoroethylene) is a high-molecular-weight polymer renowned for its versatility. It resists nearly all chemicals in the 0-14 pH range (except molten alkali metals and elemental fluorine) and performs reliably from cryogenic temperatures up to 500°F. PTFE is especially suited for food and beverage applications requiring high-purity materials, where contamination or discoloration of media must be avoided. Its extremely low coefficient of friction—lower than any known solid surface. Provides superior non-stick properties. Due to excellent chemical and thermal resistance, PTFE is a preferred gasket material in many industries.​
Red Rubber (SBR)
Style 7237 red rubber is a styrene-butadiene copolymer (SBR) offering good physical properties at an economical price. Developed as a synthetic alternative to natural rubber, it conforms well to uneven flange surfaces, with strong abrasion resistance, impact strength, resilience, and tensile strength.Red rubber is popular for hot or cold water applications and is a cost-effective choice for sturdy industrial elastomer needs. It is not suitable for oils, fuels, solvents, or hydraulic fluids. These gaskets have demonstrated long-term reliability over many years.
Compressed Non-Asbestos Sheets
Style 7001 is a high-quality compressed non-asbestos sheet made from aramid and synthetic fibers bonded with nitrile rubber (NBR). It serves as an excellent general-purpose material for process industries, water, and wastewater systems. Manufactured via a hot calender process under ISO-9001 certified quality controls, it handles media such as water, diluted alkalis, industrial gases, and general chemicals. Common applications include valves, pumps, flanges, doors, mixers, agitators, and automotive components.​

Vegetable Fiber / Oil Paper / Fish Paper
Vegetable fiber (often called Detroiter) is a treated cellulose material impregnated with protein glue and glycerin binder. It performs well in sealing applications up to 250°F, offering strength, flexibility, compressibility, and resistance to heavy pressure. Chemically treated for compatibility with oils, water, alcohol, grease, air, gas, gasoline, and solvents, it is widely used in industrial, chemical, petroleum, petrochemical, and automotive sectors.​
Oil paper jointing, a cellulose fiber base with plasticized chemical treatment, resists oil, petrol, air, water, alcohol, grease, and most solvents. It is ideal for engines, axles, pumps, pipes, and tank flanges in automotive, marine, aero, and agricultural industries.​
Fish paper is a vulcanized fiber electrical insulator, durable and flexible, suitable for motor windings, gasket insulation, and oil-filled transformers. This lightweight dielectric material provides reliable performance in electrical applications.
