Key features

• Made of Viton (fluorocarbon elastomer) for use with a variety of chemicals and fuels
• Durometer (hardness) of 75A for resistance to penetration
• Round cross-section to provide a seal between cylindrical overlapping surfaces
• For use across a wide temperature range from -15 degrees F/-26 degrees C to 400 degrees F/205 degrees C
• Meets standards defined by Aerospace Standard AS568A

This O-ring is made of brown Viton and has a durometer of 75A. It has a round cross-section and can be used across a wide temperature range (-15 degrees F/-26 degrees C to 400 degrees F/205 degrees C). Designed for use in a wide variety of sealing applications, this Viton O-ring meet standards defined by Aerospace Standard AS568A, which is the Aerospace Size Standard for O-rings. Viton (fluorocarbon elastomer) has high heat, fuel, and chemical resistance, and is compatible for use with non-flammable hydraulic fuels, silicone oil, chlorinated hydrocarbons (trichlorethylene), fuels, aromatic hydrocarbons (benzene) and aliphatic hydrocarbons (propane), as well as high vacuum environments, ozone, and weathering. Viton is vulnerable to low molecular organic acids, ammonia gas, alkalis, amines, glycol-based brake fluids, and super-heated steam. The durometer hardness of this Viton O-ring is 75A. Durometers measure the hardness of a material and its resistance to permanent indentation. A higher durometer value indicates greater resistance to indentation. On a scale of 0 to 100, a value of 0 indicates that a sample was completely penetrated, while a value of 100 shows no indentation in the
