Silicone Rubber Gaskets (-67° F to +500° F)
Silicone rubber gaskets are flexible, high-performance sealing components made from silicone elastomer, known for its wide temperature resistance, chemical stability, and long-lasting flexibility. They’re widely used in industries like aerospace, medical, food processing, electronics, and automotive, especially in environments where heat, cold, or UV exposure are factors.
Silicone Sponge Gaskets (-67° F to +500° F)
Silicone sponge gaskets are sealing components made from silicone sponge material, which is a soft, compressible, closed-cell or open-cell foam. These gaskets are commonly used in industrial, automotive, medical, and electronic applications where reliable sealing, cushioning, or thermal insulation is needed—especially in environments that involve extreme temperatures, moisture, or UV exposure.
Poron® Gaskets (-40° F to 195° F)
PORON® gaskets are made from PORON® polyurethane foam, a microcellular, open-cell material developed by Rogers Corporation. These gaskets are widely used for sealing, cushioning, and vibration damping in applications that demand long-term durability, precise compression, and consistent performance.
EPDM Gaskets (-60° F to 300° F)
EPDM gaskets are sealing components made from EPDM rubber (Ethylene Propylene Diene Monomer), a durable synthetic elastomer known for its excellent resistance to weather, ozone, UV, water, and a wide range of temperatures. EPDM gaskets are commonly used in automotive, water and pumping systems, electrical enclosures and other industrial sealing applications.
Neoprene Gaskets (-40° F to 230° F)
A neoprene gasket is a sealing component made from neoprene rubber—a versatile synthetic elastomer also known as polychloroprene. Neoprene gaskets are valued for their moderate oil and chemical resistance, good weatherability, and excellent flexibility, making them a popular choice across a wide range of industries.
EPP Gaskets (-40° F to 230° F)
An EPP gasket is a sealing or cushioning component made from Expanded Polypropylene (EPP) foam. EPP is a lightweight, closed-cell, bead-foam material known for its excellent energy absorption, thermal insulation, and reusability. It’s widely used in automotive, packaging, HVAC, and consumer products—especially where impact resistance and thermal insulation are key. Its closed-cell structure offers good water, oil, and chemical resistance.
RN-8011 Gaskets (to 350° F)
RN-8011 is a compressed non-asbestos gasket material manufactured by Garlock, designed for industrial sealing applications where high performance is needed without the use of asbestos. RN-8011 is made from a blend of aramid fibers, inorganic fillers, and a nitrile rubber (NBR) binder. It's a general-purpose gasket sheet known for good chemical resistance, moderate temperature tolerance, and mechanical strength.
Fish Paper Gaskets (to 239° F)
A fish paper gasket is a type of electrical insulating gasket made from fish paper, which is a durable, flexible, cellulose-based fiber material. It’s commonly used in electrical and electronic applications due to its excellent dielectric strength, heat resistance, and mechanical stability. Fish paper is thin and lightweight, and is often used in tight spaces or layered between parts.
Lexan® Gaskets (-40° F to 240° F)
Lexan® gaskets are sealing, spacing, or insulating components made from Lexan, a brand of polycarbonate (PC) plastic manufactured by SABIC. Lexan is known for being extremely tough, optically clear, and heat- and impact-resistant, making it suitable for protective, insulating, or transparent gasket applications. Can be thermoformed or die cut into complex shapes.
Cork Rubber Gaskets (-15° F to 230° F)
Cork rubber gaskets are sealing components made from a composite material that combines natural cork particles with elastomeric rubber binders (such as Nitrile—NBR, Neoprene, EPDM, or Silicone). This blend results in a compressible, resilient, and oil-resistant gasket material commonly used for sealing fluids, reducing vibration, and insulating parts in industrial and automotive settings.
