Lamons 157 Fluorosilicone O-Ring 70A Shore Blue, Sterling Seal (Pack of 1000)

Fluorosilicone has very good resistance to ozone, weathering, detergent, salt water, engine and transmission oil, non-petroleum brake fluid, hydraulic fluids that resist fire, vegetable and animal oils, high molecular weight chlorinated aromatic hydrocarbons, and has better mineral oil, fuel, and aromatic hydrocarbons (benzene) compatibility than Fluorosilicone. Fluorosilicone is vulnerable to mechanical wear and tear, water and steam over 250 degrees F (121degrees C), chlorinated hydrocarbons (trichloroethylene), acids and bases, and hydrocarbon fuels.

• Made of Fluorosilicone rubber for use with a variety of fluids
• O-ring Size - Actual (b) per AS568A Metric O-ring Size per AS568A (b)ID (Nominal): 4-1/2 OD (Nominal): 3/32 CS (Nominal): 4-11/16
• Durometer (hardness) of 70A for resistance to penetration
• Round cross-section to provide a seal between cylindrical overlapping surfaces
• Can be used across a wide temperature range from -100 degrees F (-73 degrees C) to 350 degrees F (177 degrees C)
