EPDM Gaskets
Due to the EPDM rubber materials’ excellent resistance to aging, ozone, and weathering, the EPDM rubber gaskets are widely used in external applications. The EPDM gaskets are made of EPDM rubber elastomer and have an impermeable surface which is ideal for use with most alkalines, ketones and diluted acids, offering strong abrasion resistance.
In medium-range sealing applications, EPDM gaskets are widely used and as flange gaskets, manway seals or low-pressure pipe seals. We offer EPDM Gaskets in food-safe or Drinking water approved versions – from FDA or WRAS/WRc certified. Our specialty are regular EPDM gaskets as well as white food quality EPDM gaskets for use with potable drinking water or for foodstuffs.
EPDM gaskets are the most often specified gasket choice because of their ozone resistance. If your gasket will be outdoors and exposed to temperatures between -40 C and 120 C the EPDM gasket is a great choice.

Non-Asbestos Gaskets
We cut Non-Asbestos Gaskets from all the major manufacturers’ materials including, Klinger, Frenzelit, Temac, Gambit, or any of the private branded styles. We can cut your gaskets using a waterjet, lasers, or with a cutting plotter as per your request.
Cut to your dimensions from Non-Asbestos gasket materials.
Most of today’s non-asbestos gasket materials contain either Kevlar, an aramid fiber, fiberglass, carbon, graphite or another mineral fiber.
Regardless of the gasket sheets manufacturer, the basics are the filler and the elastomer used. While no two gasket compounds (or the % of filler) are identical, the basic Elastomers are NBR (Buna-N), SBR, EPDM or Neoprene.
If you examine which gasket material you need (as defined by the application) and select the non-asbestos gasket material with that elastomer you will usually do well. This method will also allow you to select a competitive brand that will serve your application. No two materials are identical so caution must always be exercised. In general, the common “Binders” are:
- NBR – good for oils, gas, mild chemicals and water
- SBR – good for saturated Steam, mild chemicals inert gas and water
- Neoprene – good for saturated steam, refrigerants, oils, fuels, mild acids and alkalies and water.
- EPDM – good for saturated steam, mild chemicals and water
Each material listed regardless of manufacture will indicate the “Binder” which makes cross-referencing equal materials a much easier task. You should however pay attention to Tensile strength (for pressure resistance) Temperature ratings, and Compression / Recovery ratings.
You must also consider for cut gaskets Size, Temperature, Application, Media, Pressure, Speed (if dynamic) of your specific application. If this is for a finished gasket you will also want to consider bolt loads, the size of bolts, the number of bolts, the bolt material and the available torque.
Silicone Gaskets
Silicone gasket sheet material is a very versatile material ideal for a wide range of applications. Silicone rubber gasket material offers temperature resistance, weather (UV and ozone) resistance, and fire resistance. Silicone gasket material has very good compression set resistance allowing it to maintain a proper seal over many years.
Silicone gaskets offer exceptional high and low-temperature capability while maintaining excellent flexibility. Normally manufactured by molding or die-cutting of sheet stock. Silicone rubber offers the advantages of lower molding pressures compared to organic rubber, as well as low toxicity and low odor.
Silicone gasket material is not recommended for dynamic applications due to its poor tear strength and tensile. It does not do well with oils. It does however do well in most gasketing (static) applications and seals at lower bolt loads than most rubber materials due to its low durometer.
The temperature range on most silicone gasket materials is -40 C to +230°C . Consult with us for your specific application. Silicone gaskets available in thickness of 1, 2, 3, 4, 5, 6, 8 and 10 mm

Peroxide-cured EPDM Gaskets
When utilized in industrial settings, EPDM peroxide cured gaskets and seals are subjected to a range of pressures and temperatures as well as severe chemicals. These seals and gaskets are made from a range of elastomeric materials to withstand harsh conditions.
These seals are made from two common elastomeric materials: neoprene and EPDM. Neoprene gaskets and seals can survive a variety of harsh circumstances, although EPDM is thought to be a superior material.
Peroxide and sulfur are used to cure EPDM in order to enhance its properties for certain applications. Due to its unique qualities, peroxide-cured EPDM material is now the more preferred of the two.
In medium-range sealing applications, EPDM gaskets are widely used and as flange gaskets, manway seals or low-pressure pipe seals.

FVMQ Fluorosilicone Gaskets
FVMQ FluoroSilicone rubber gaskets are made of fluorosilicone or fluorinated silicone rubber. Regular Silicone gaskets should not be used with substances that include oil or petroleum. Fluorosilicone is then used in this situation.
The fluorsilicone gaskets are resistant to very hot temperatures. Additionally, they are resistant to solvents, oils, and other substances made from petroleum.
Fluorosilicone FVMQ gasket material is not recommended for dynamic applications due to its poor tear strength and tensile. It does not do well with oils. It does however do well in most gasketing (static) applications and seals at lower bolt loads than most rubber materials due to its low durometer.
The temperature range on most silicone gasket materials is -40 C to +230°C . Consult with us for your specific application. Silicone gaskets available in thickness of 1, 2, 3, 4, 5, 6, 8 and 10 mm
Fluorosilicone, sometimes referred to as FVMQ, is a kind of saturated rubber substance. It has chemical resistance qualities similar to fluorocarbons and silicone-like excellent stability in high temperatures.
Fluorosilicone is a very adaptable material that may be utilized in a variety of sealing applications, including outdoor applications and those that are exposed to sunshine, ozone, chlorinated or aromatic hydrocarbons, and it is frequently specified for aerospace usage. FMVQ has strong resistance to gasoline, oil, and solvents and good compression set characteristics. These characteristics of the material remain unchanged throughout a temperature range of -75° to 400°F (-59° to 204°C).
Fluorosilicone has a high coefficient of friction, low abrasion resistance, and limited physical strength, making it appropriate for static sealing applications but not for dynamic sealing operations.
