Is the O-ring seal FPM (Viton) 80 Shore suitable for general-purpose oil and fuel applications?

Yes. The O-ring seal FPM (Viton) 80 Shore is suitable for general-purpose oil and fuel applications. FPM (Viton) is a fluorocarbon elastomer known for excellent resistance to hydrocarbons, motor oils, fuel, and many chemicals, and an 80 Shore A hardness gives a good balance of resilience and sealing force for static and many dynamic sealing uses. However, confirm compatibility with the specific fluids, temperatures, pressures and dynamic conditions of your application: Viton typically performs well from about -20Â°C to +200Â°C (short-term up to ~250Â°C), resists most petroleum-based oils and fuels, but may be less suitable with certain aggressive chemicals (strong acids, ketones) or very low-temperature flexibility needs. Also verify groove design, extrusion gaps and whether the hardness suits dynamic wear or requires a softer/harder compound for optimal sealing life.

Can O-ring seal, FPM (Viton) 80 Shore withstand continuous exposure to high-temperature fluids?

O-ring seal, FPM (Viton) Format: Viton (fluoroelastomer) with 80 Shore hardness offers excellent resistance to high temperatures and aggressive fluids compared with many elastomers. Continuous exposure limits depend on exact grade: typical Viton A handles continuous service up to ~200â230Â°C; some high-temperature fluoroelastomer grades can tolerate short-term peaks higher. At 80 Shore, the compound is relatively firm, which helps mechanical stability but does not change chemical temperature limits much. Long-term exposure to hot oils, steam above recommended temperatures, or oxidizing fluids will accelerate hardening, loss of elasticity and eventual leakage. For continuous high-temperature service, verify the specific Viton grade, operating temperature, fluid chemistry and pressure; when in doubt, choose a high-temp fluoroelastomer or metal/graphite seal.

Does O-ring seal, FPM (Viton) 80 Shore resist common solvents like ketones and esters?

O-ring seal, FPM (Viton) Format: short answer. generally no; Viton (FPM) with 80 Shore hardness has good resistance to many oils, fuels, aromatic hydrocarbons and some aggressive chemicals, but it is not broadly resistant to common ketones (e.g., acetone, MEK) or many esters. Ketones and many esters tend to cause swelling, softening and loss of mechanical properties in fluorocarbon elastomers. Performance depends on concentration, temperature, exposure time and dynamic vs. static sealing: - Ketones (acetone, methyl ethyl ketone, etc.): typically attack FPM/Viton. significant swelling and degradation likely, especially at elevated temperatures or prolonged contact. Not recommended. - Esters (ethyl acetate, butyl acetate, glycol esters): many esters will also swell and soften Viton; short-term, low-temperature exposure may be tolerated in some cases, but generally not reliable for sealing applications where chemical resistance is critical. - Exceptions: some specialized fluorocarbon formulations (e.g., high-performance grades or copolymers) improve resistance to certain esters/ketones, but standard FPM (Viton) 80 Shore is not guaranteed resistant. Recommendation: For applications involving common ketones or esters, verify with manufacturer chemical compatibility charts, perform application-specific swelling and aging tests, or consider alternative elastomers (e.g., PTFE, EPDM, HNBR, perfluoroelastomers) selected for proven resistance to those solvents.
