Compound Specification Guide
| Prefix | Material | Duro. | Temperature Range | Description |
|---|---|---|---|---|
| N70 | Nitrile | 70 +/- 5 | -40°C to 120°C -40°F to 248°F | A nitrile compound that can be used for a wide range of applications including petroleum based fluids. Nitrile compounds resist compression set, tear and abrasion resistance. |
| N90 | Nitrile | 90 +/- 5 | -25°C to 120°C -13°F to 248°F | Typically used for pressures higher than the 70 durometer materials, while having comparable media resistance. |
| LTN | Nitrile | 70 +/- 5 | 55°C to 120°C -67°F to 248°F | A low temperature resistant Nitrile compound to be used in seals at lower temperatures. The lower acrylonitrile shows slightly less resistance to petroleum products. |
| HS7 | Hydrogenated Nitrile | 70 +/- 5 | -40°C to 150°C -40°F to 302°F | Hydrogenated Nitrile is resistant to heat, ozone and aging. It has relative applications to Nitrile, but also has better mechanical properties and media resistance. Recommended for oilfield and automotive applications. H2S resistance up to 10%. |
| HS8 | Hydrogenated Nitrile | 80 +/- 5 | -40°C to 150°C -40°F to 302°F | Typically used for higher pressures than the 70 durometer materials and has comparable media resistance. |
| HS9 | Hydrogenated Nitrile | 90 +/- 5 | -40°C to 150°C -40°F to 302°F | Most often used for higher pressures than the 80 durometer materials and has comparable media resistance and improved ED resistance. |
| V75 | Viton™ | 75 +/- 5 | -25°C to 204°C -13°F to 400°F | Viton™ compounds have excellent resistance to ozone, weather, oxygen, mineral oil, fuels, hydraulic fluids, aromatics, petroleum fluids, organic solvents and chemicals. Vitom™ also has high resistance to high temperature applications. Vitom™ Extreme ETP compounds is also available. ETP provides thermal resistance of Viton™ and advanced chemical resistance. |
| V90 | Viton™ | 90 +/- 5 | -25°C to 204°C -13°F to 400°F | Viton ™ is commonly used for higher pressure than the 75 durometer materials while having comparable media resistance. |
| LTV | Viton™ GLT | 75 +/- 5 | -40°C to 204°C -40°F to 400°F | Viton™ GLT is used for lower temperature applications compared to the 75 durometer materials. The Viton™ GLT also has comparable media resistance. |
| PF7 | Perfluoroelastomer | 75 +/- 5 | -15°C to 300°C 5°F to 572°F | Perfluroelastomer materials incorporate heat and chemical resistance that excels beyond comparable elastomer products. |
| PF9 | Perfluoroelastomer | 90 +/- 5 | -4°C to 230°C 25°F to 466°F | Typically used in higher pressure than the 75 durometer materials while having comparable media resistance. |
| A80 | Aflas™ | 80 +/- 5 | 0 C°to 230°C 32 F°to 446°F | Tetrafluoroethylene-Propylene materials provide advanced thermal and chemical resistance, which incorporates hot water, steam, acids, alkaline solutions, ammonia, amines, brake fluids, petroleum fluids and sour gas. Please note that low temperature may impact sealing abilities. |
| NEO | Neoprene | 70 +/- 5 | -45°C to 135°C -49°F to 275°F | Neoprene is a general purpose material for refrigerants, ozone and weather. |
| E70 | Ethylene- Propylene | 70 +/- 5 | -54°C to 150°C -65°F to 302°F | Ethylene- Propylene materials provide great resistance to water, steam, brake fluids, and ozone. |
| E80 | Ethylene- Propylene | 80 +/- 5 | -54°C to 150°C -65°F to 302°F | Commonly used in pressures greater than 70 durometer EPDM compounds and has comparable media resistance. |
| S70 | Silicone | 70 +/- 5 | -55°C to 230°C -67°F to 446°F | Silicone compounds have the widest elastomer temperature range, but shouldn’t be used in dynamic applications or petroleum fluids. |
| FS7 | Fluorosilicone | 70 +/- 5 | -55°C to 200°C -67°F to 392°F | Fluorosilicone can be used in petroleum and synthetic oils, greases, amines, amine-treated hydrocarbons and steam. |
| TEV | PTFE Encapsulated Viton | -60°C to 205°C -76°F to 401°F | ||
| TES | PTFE Encapsulated Silicone | -60°C to 205°C -76°F to 401°F |
