Customer Questions & Answers
-
Question:
What is a Buna-N O-Ring and what are its uses?
Answer: A Buna-N O-Ring is a circular seal made from a synthetic rubber compound known for its excellent resistance to oil, chemicals, and heat. These O-Rings are commonly used in various applications, including plumbing, automotive, and industrial machinery, to prevent leaks and maintain pressure. Their durability makes them suitable for sealing fluids and gases in high-stress environments. -
Question:
What is the durometer rating of this O-Ring and what does it mean?
Answer: This O-Ring has a durometer rating of 70A, indicating its hardness on the Shore A scale. A durometer rating of 70A means it’s relatively firm yet flexible, providing a good balance of durability and compressibility. This rating makes it ideal for applications that require resilience while also allowing for the necessary sealing ability in various conditions. -
Question:
What dimensions do these O-Rings have and why are they important?
Answer: The O-Rings have an inner diameter (ID) of 4-1/2 inches, an outer diameter (OD) of 4-3/4 inches, and a width of 1/8 inch. These dimensions are crucial because they determine how well the O-Ring fits into a specific groove or housing. Proper sizing ensures a tight seal, preventing leaks and maintaining system integrity. Using the right dimensions is essential for effective performance in sealing applications. -
Question:
Are these O-Rings suitable for high-pressure applications?
Answer: Yes, Buna-N O-Rings are well-suited for moderate pressure applications. Their robust construction and chemical resistance enable them to perform effectively in high-pressure scenarios, such as hydraulic systems or pneumatic applications. However, for extremely high-pressure conditions, it may be wise to consult with a technical expert to ensure suitability and optimal performance. -
Question:
Can Buna-N O-Rings be used in food applications?
Answer: Buna-N O-Rings are typically not recommended for direct food contact or applications involving potable water as they may contain additives that are not food-safe. For food applications, it is better to use O-Rings specifically designed for such purposes, such as silicone or EPDM types. Always check the material compatibility before use to ensure safety. -
Question:
How many O-Rings come in a pack?
Answer: This product comes in a pack of 10 O-Rings, making it a convenient choice for both small repairs and larger projects. Having multiple rings on hand means you can easily replace or install them as needed without the hassle of reordering frequently. This bulk option is perfect for workshops, home improvement projects, or routine maintenance. -
Question:
What colors are these O-Rings available in?
Answer: These specific O-Rings are available in black, which is standard for Buna-N materials due to the carbon black used in the manufacturing process. While black is the most common, other colors may be available in different materials to signify various properties or for aesthetic purposes. Always check product specifications for available colors if needed. -
Question:
What is the temperature range for Buna-N O-Rings?
Answer: Buna-N O-Rings typically operate effectively within a temperature range of -40°F to 250°F (-40°C to 121°C). This makes them suitable for a wide range of applications, from automotive engines to industrial machinery, where fluctuations in temperature can occur. Understanding the temperature limits is vital for ensuring they provide the reliable sealing performance you need. -
Question:
How do I install an O-Ring properly?
Answer: To install an O-Ring, clean the groove where it will be placed to remove debris. Lightly lubricate the O-Ring with a compatible lubricant to facilitate easy installation and prevent damage. Carefully stretch the O-Ring and place it into the groove, ensuring it sits evenly without twists. Proper installation maximizes the sealing efficiency and longevity of the O-Ring. -
Question:
