Customer Questions & Answers

  • Question: What is the durometer rating of the Captain O-Ring, and why is it important?

    Answer: The Captain O-Ring has a 90A durometer rating, indicating a firm and durable material. The durometer scale measures the hardness of a rubber-like substance, which makes this O-Ring suitable for applications that require resilience against pressure and wear. Being 90A, it's ideal for use in high-stress environments such as seals in machinery or plumbing applications, where it's essential to maintain a reliable barrier without deforming.
  • Question: What are the primary uses for the Captain O-Ring?

    Answer: Captain O-Rings are versatile and can be used in various applications including sealing hydraulic and pneumatic equipment, plumbing, and automotive components. The round shape and durable polyurethane material ensure they provide a reliable seal in situations involving oil, water, or other fluids. This makes them especially useful in household repairs or light industrial uses, offering both functionality and longevity in your projects.
  • Question: Is the Captain O-Ring resistant to chemicals?

    Answer: Yes, the Captain O-Ring, made of polyurethane, exhibits excellent resistance to many chemicals, including grease, oil, and solvents. This characteristic allows it to maintain its structural integrity and sealing properties in environments where exposure to harsh substances is common. For example, if you’re working on automotive repairs where oils or fuels are present, these O-Rings will ensure proper sealing without degrading over time.
  • Question: Can the Captain O-Ring be used in high-temperature applications?

    Answer: While the Captain O-Ring is durable, it’s essential to note that polyurethane generally has a moderate temperature tolerance. It performs well under high strain and moderate thermal conditions typical for most applications. However, for extreme high-temperature usage, it may not be the best choice. It's often selected for scenarios in DIY projects or light industrial tasks where temperature extremes are not a critical factor.
  • Question: What is the size and dimensions of the Captain O-Ring?

    Answer: The Captain O-Ring is classified as a size 011, which typically has an inner diameter of about 0.682 inches (17.30 mm) and a cross-section thickness of 0.103 inches (2.62 mm). This size is commonly needed in various applications ranging from plumbing fixtures to automotive parts, ensuring a secure and effective seal in both consumer and industrial use cases.
  • Question: How many O-Rings are included in a pack?

    Answer: Each pack of Captain O-Rings contains 25 pieces, providing ample stock for multiple projects or repairs. This bulk packaging is beneficial for individuals or businesses that frequently use O-Rings, allowing for efficient inventory management. Whether you are a DIY hobbyist or a professional mechanic, having a sufficient number of O-Rings on hand helps cover unexpected repairs without delays.
  • Question: Are the Captain O-Rings suitable for food-grade applications?

    Answer: While polyurethane is durable, it's crucial to determine if the specific formulation of the Captain O-Ring is FDA-approved for food contact. Many O-Ring materials are not food-grade certified due to potential leaching of chemicals. If your application involves food processing or handling, always verify the certification to ensure safety. For applications outside of food, these O-Rings excel in industrial and plumbing uses.
  • Question: How do I know if the Captain O-Ring is the right size for my needs?

    Answer: To determine if the Captain O-Ring is the right size, first measure the groove or fitting where the O-Ring will be placed. Ensure the inner diameter and cross-section dimensions match the specifications of your project. This ensures a proper and effective seal. For example, if you’re sealing a pipe fitting, using the correct size will prevent leaks and enhance overall efficiency in your system.
  • Question: Can these O-Rings be reused after installation?

    Answer: In general, O-Rings are designed for single use to ensure a tight seal. However, if removed carefully without damage, they can sometimes be reused, especially in low-pressure applications. Be cautious about wear and deformation; if they appear compromised, replacing them is advisable. This practice is common in applications where quick repairs are necessary, but always inspect the O-Rings before reinstallation.
  • Question: Where can I buy the Captain O-Ring Polyurethane O-Ring, 011 90A Durometer, Round, Translucent (25 Pack) in São Tomé and Príncipe?
