Question:
What is a Viton O-Ring and what are its advantages?
Answer: A Viton O-Ring, such as the Mr O-Ring 249, is made from a high-performance synthetic rubber compound known for its excellent resistance to chemicals, heat, and compression set. These qualities make it ideal for applications involving oils, fuels, or other aggressive media. The durability and stability of Viton allow O-Rings to maintain their integrity over prolonged use in challenging conditions, ensuring effective sealing in automotive, aerospace, and industrial applications. -
Question:
What does the 75A durometer rating mean for the Mr O-Ring?
Answer: The 75A durometer rating indicates the hardness of the Viton material. A rating of 75A signifies a firm yet flexible O-Ring that can withstand various compression loads while providing a reliable seal. This hardness level strikes a balance between flexibility and durability, making it suitable for dynamic applications where movement occurs, such as in pumps and actuators. -

What are the dimensions of the Mr O-Ring 249?
Answer: The Mr O-Ring 249 features an inner diameter of 4-7/8 inches, an outer diameter of 5-1/8 inches, and a cross-section of 1/8 inch. These precise dimensions are critical for ensuring a proper fit in your assemblies, minimizing leakage potential and ensuring optimal performance in sealing applications. This specific size is commonly used in hydraulic and pneumatic systems, as well as in various machinery. -
Question:
In what applications can I use the Mr O-Ring 249?
Answer: The Mr O-Ring 249 is suitable for a variety of applications, including automotive, industrial, and HVAC systems. Its excellent chemical resistance allows it to perform well in oil sealing applications, while the size and hardness make it effective in high-pressure environments. Common uses include sealing hydraulic cylinders, valves, and pumps, where maintaining pressure and preventing leaks is essential. -
Question:
How do I know if this size O-Ring will fit my application?
Answer: To determine if the 4-7/8-inch ID and 5-1/8-inch OD of the Mr O-Ring 249 will fit your application, you should measure the existing O-Ring or the groove it needs to fit in. Ensuring the dimensions match is vital for effective sealing; otherwise, leaks can occur. Additionally, consider the durometer rating to ensure it meets the flexibility and hardness needed for your specific conditions. -
Question:
Is the Mr O-Ring 249 temperature resistant?

Can I use the Mr O-Ring 249 for water sealing?
Answer: While the Mr O-Ring 249 is primarily designed for oil and chemical resistance, it can also be used in water sealing applications. However, it's essential to consider the type of water and any additives involved, as certain conditions may affect the integrity of the Viton seal. For general water sealing needs, the O-Ring can provide reliable performance, especially in environments where water conditions are stable. -
Question:
How many O-Rings come in a pack?
Answer: The Mr O-Ring 249 is sold in packs of 25, providing ample supply for multiple projects or repairs. This pack size is convenient for both individual users and professionals who need a consistent and reliable source of O-Rings for ongoing maintenance or production needs.
