M1.5x11 Viton O-Ring, 75A Durometer, Round, Green Viton, 11 mm ID, 14 mm OD, 1.5 mm Width (Pack of 10)… Chemical Resistance: Viton o-rings are highly resistant to a wide range of chemicals, including mineral oil, fuels, hydraulic fluids, aromatics, and organic solvents. This makes them a preferred choice for sealing applications in industries where exposure to such chemicals is common. Temperature Range: Viton o-rings are well-known for their excellent temperature resistance. They can withstand a wide temperature range, from -26°C (-15°F) to 232°C (450°F). This makes them suitable for use in extreme temperature environments, including both high and low-temperature applications. Durometer Hardness: The 75A durometer hardness indicates the material's hardness or stiffness. A durometer of 75A is considered a medium hardness, offering a good balance between flexibility and resistance. This level of hardness is suitable for a wide range of sealing applications. Cross-Section: Round cross-section of 1.5mm
