Hex Head Bolt: 5/8-11, 3" Length, Alloy Steel, Grade B7 MPN:0155493

The 0.139-inch thick nitrile butadiene rubber (NBR) O-ring has an inside diameter (ID) of 3.734 inches and an outside diameter (OD) of 4.012 inches, making it suitable for use in sealing applications that require a good balance between flexibility and compression resistance. It is commonly used in industries such as automotive, aerospace, and manufacturing where O-rings are essential for creating leak-proof seals. Its dash 240 specification indicates it is a general-purpose grade of nitrile rubber that provides good chemical resistance and mechanical strength, making it suitable for use with various fluids and media. It offers good resistance to oils, aliphatic hydrocarbons, water, and petroleum-based fluids, which make it an ideal choice for sealing hydraulic and pneumatic applications. Its ability to handle harsh chemicals and temperatures between -40F and +212F makes it suitable for use in a wide range of environments where durability and reliability are critical factors. Overall, this O-ring provides an effective solution for sealing various industrial components, ensuring that fluids and gases remain contained, reducing the risk of leaks or failures, and preventing costly downtime and damage to equipment.
