Customer Questions & Answers

  • Question: What is Buna-N O-Ring Cord Stock used for?

    Answer: Buna-N O-Ring Cord Stock is commonly used for sealing applications in various industries, such as automotive, aerospace, and plumbing. Its rubber composition provides excellent chemical resistance and durability, making it suitable for environments where exposure to oils, fuels, and water is common. The elasticity of the material allows it to compress and form a tight seal when placed between two surfaces, preventing leakage in applications like hydraulic systems or machinery.
  • Question: What is the significance of the 70A durometer rating?

    Answer: The 70A durometer rating refers to the hardness of the Buna-N O-Ring Cord Stock, indicating it has a medium hardness. This level of hardness strikes a balance, allowing for effective sealing while maintaining flexibility. It's suitable for applications that require both resilience and the ability to conform to uneven surfaces. For instance, when used in plumbing fixtures, it helps ensure a waterproof seal that adapts even under varying pressures.
  • Question: Is the .275" thickness ideal for all applications?

    Answer: The .275" thickness of this Buna-N O-Ring Cord Stock is versatile, making it a great choice for many applications, but it may not be suitable for every scenario. Thicker O-rings can provide better compression and resistance to wear, while thinner ones may fit into tighter spaces or low-pressure situations. Therefore, it is essential to assess the specific needs of your project, such as pressure levels and available space, before choosing the thickness.
  • Question: Can this O-Ring Cord Stock be cut to size?

    Answer: Yes, the Buna-N O-Ring Cord Stock can be easily cut to the desired length for your specific application. This feature is particularly beneficial for users who need custom-length seals. By measuring the required length and using a sharp blade or scissors, you can create O-rings that fit precisely. This practice allows flexibility in various projects, ranging from DIY home repairs to industrial applications.
  • Question: What temperature range can this O-Ring handle?

    Answer: Buna-N O-Ring Cord Stock typically operates effectively within a temperature range of -20°F to 200°F (-29°C to 93°C). This wide range makes it suitable for a variety of applications, from household plumbing to automotive systems, where temperature fluctuations can occur. However, exceeding this range can lead to deterioration or loss of sealing capability, so it's crucial to maintain temperature control within these limits.
  • Question: Does Buna-N O-Ring Cord Stock resist chemicals?

    Answer: Buna-N is known for its excellent chemical resistance, particularly against common hydrocarbons, oils, and water. This makes it an ideal choice for environments where exposure to these substances is expected, such as automotive applications or fuel systems. However, it may not be suitable for some aggressive solvents or acids, so it’s important to check compatibility with specific chemicals prior to use, ensuring you select the right material for your application.
  • Question: How do I install the O-Ring Cord Stock?

    Answer: Installing Buna-N O-Ring Cord Stock is straightforward; first, ensure the surface where the O-ring will sit is clean and free of debris. Then, measure and cut the cord stock to the required length, ensuring a clean, straight cut. Simply place the O-ring into its designated groove or space, ensuring a snug fit. This simple installation method allows you to create custom seals easily, making it convenient for projects where standard sizes may not apply.
  • Question: Can I use this O-Ring Cord Stock outdoors?

    Answer: Yes, Buna-N O-Ring Cord Stock can be used outdoors, as it is designed to withstand environmental exposure, including moisture and UV light. However, prolonged exposure to sunlight can eventually degrade the material, so it's wise to use it in applications where it won’t be continuously exposed to harsh sunlight. Utilizing this cord stock in outdoor equipment can help ensure reliable performance in various weather conditions.
  • Question: What dimensions are included in the product specifications?

    Answer: The product features a nominal diameter measurement of 1/4 inch, with a precise thickness of .275 inches. Additionally, the stock is available in a length of 10 feet, allowing for multiple applications from a single piece. This range of dimensions makes it versatile for various sealing needs, whether in automotive, plumbing, or other mechanical systems, where custom sealing solutions are often required.
  • Question: Where can I buy .275' (1/4" Nominal, 7 mm) Buna-N O-Ring Cord Stock in Saint Lucia?

Mr O-Ring O-Rings Editorial Review

This product is a 1mm Buna-N O-Ring Cord Stock, 70A Durometer, with a thickness of 0.039" and is available in a 10' piece. According to the Q&A section, this product is not suitable for use in a microwave oven, will not float in water, can be joined using super glue, and is not recommended for use as a drive belt. Reviews indicate that the product arrived quickly and was exactly what the customers were looking for in terms of material and size. However, one customer received a shorter piece than advertised. The product has been used for making jewelry, as well as for seals on various equipment. The use of super glue is suggested for making end connections, and it can elongate up to 20% of its length.
