Product Description

230 Silicone O-Ring, 70A Durometer, Red, 2-1/2" ID, 2-3/4" OD, 1/8" Width (Pack of 10)

About This Item

Introducing the 230 Silicone O-Ring Pack of 10 - the perfect solution for all your sealing needs. Designed with precision and durability in mind, this red silicone O-ring is round in shape and has a durometer of 70A, making it ideal for a wide variety of sealing applications. Whether you're working with engines, faucets, flanges, valves, or cylinders, this O-ring is sure to provide a reliable and effective pressure and fluid seal. One of the standout features of this O-ring is its temperature resistance.

It can withstand temperatures ranging from -65 degrees F (-54 degrees C) to 450 degrees F (232 degrees C), making it suitable for both hot and cold sealing applications. This means you can use it with confidence in a range of environments. Additionally, this silicone O-ring exhibits excellent resistance to ozone, weather, detergent, salt water, engine and transmission oil, non-petroleum brake fluid, hydraulic fluids that resist fire, vegetable and animal oils, as well as high molecular weight chlorinated aromatic hydrocarbons. This ensures that it will maintain its effectiveness and durability even in challenging conditions. It's important to note that while silicone is highly resistant to many substances, it is vulnerable to mechanical wear and tear, water and steam over 250 degrees F (121 degrees C), aromatic hydrocarbons (benzene), chlorinated hydrocarbons (trichloroethylene), acids and bases, and hydrocarbon fuels.

It's always recommended to use this O-ring within its specified limits for optimal performance. Moreover, this silicone O-ring is manufactured in compliance with the Aerospace Standard AS568A, which is the Aerospace Size Standard for O-rings. This means you can trust its quality and reliability for your sealing applications. With a nominal inside diameter (ID) of 2-12" and an outer diameter (OD) of 2-34", this pack includes 10 O-rings, ensuring that you have an ample supply for your projects. The cross-sectional (CS) diameter is 18", offering a secure and tight seal. Don't compromise on quality and performance.

Choose the 230 Silicone O-Ring Pack of 10 for all your sealing needs. With its high temperature resistance, superior durability, and excellent sealing capabilities, this O-ring is the perfect choice. Order yours today and experience the difference for yourself.

Customer Questions & Answers

  • Question: What are the main applications for 230 Silicone O-Ring, 70A Durometer?

    Answer: The 230 Silicone O-Ring is primarily used in sealing applications across various industries, including automotive, plumbing, and machinery. Its 70A durometer hardness provides a good balance between flexibility and strength, making it ideal for environments where resistance to high temperatures and chemicals is essential. Common use scenarios include sealing tanks, preventing leaks in plumbing fixtures, and ensuring airtight connections in HVAC systems.
  • Question: What does the 70A durometer rating mean in terms of hardness?

    Answer: The 70A durometer rating refers to the hardness of the silicone material used in the O-Ring. This rating on the Shore A hardness scale indicates that the O-Ring strikes a balance between being soft enough to create a tight seal while being durable enough to resist deformation under pressure. This makes it suitable for applications that require flexibility without sacrificing strength, such as in various mechanical assemblies or engine parts.
  • Question: How should I determine the correct size O-Ring for my application?

    Answer: To determine the right size O-Ring, you need to measure the inner diameter (ID) and outer diameter (OD) of the fitting where the O-Ring will be placed. For the 230 Silicone O-Ring, the ID is 2-12 inches, and the OD is 2-34 inches. Ensuring that the size matches your specifications accurately will help eliminate leaks and improve efficiency in your application, whether it’s in a hydraulic system or a kitchen appliance.
  • Question: Are Silicone O-Rings resistant to chemicals and extreme temperatures?

    Answer: Yes, Silicone O-Rings are known for their excellent resistance to a wide range of chemicals, including acids, bases, and solvents. Additionally, they can perform well in extreme temperature conditions, typically ranging from -70°F to +450°F, making them ideal for both hot and cold environments. This combination of properties makes them suitable for various applications from automotive to aerospace where sealing integrity is critical under harsh conditions.
  • Question: What are the advantages of using Silicone O-Rings over other materials?

    Answer: Silicone O-Rings offer several advantages, including superior temperature resistance, excellent flexibility, and low compression set. Unlike rubber O-Rings, silicone maintains its properties in both hot and cold applications, which is vital for consistent performance. Their resilience makes them especially effective in sealing applications, reducing the risk of leaks over time. This makes them optimal for industries that rely on longevity and reliability in their components.
  • Question: Can these O-Rings be used in food-grade applications?

    Answer: Silicone O-Rings can be used in food-grade applications, but it is essential to ensure that the specific silicone material is approved for food contact. Regular silicone may not meet FDA or other safety standards. If you are working in the food industry, check for certification labels when selecting O-Rings to avoid potential health risks. Their resistance to high temperatures also makes them suitable for applications like sealing containers used for cooking or storage.
  • Question: Is it important to lubricate Silicone O-Rings during installation?

    Answer: Lubricating Silicone O-Rings during installation is recommended to facilitate a smoother fit and reduce the risk of tearing or damaging the O-Ring. A compatible lubricant helps minimize friction when sliding the O-Ring into place. This is especially important in applications with tight tolerances or when the O-Ring will be subjected to significant movement. Always choose a lubricant that is compatible with silicone to preserve its integrity.
  • Question: What is the difference between the 2-12 ID and 2-34 OD measurements?

    Answer: The 2-12 inch ID (inner diameter) measurement represents the size of the hole or groove where the O-Ring will fit, ensuring a snug seal. The 2-34 inch OD (outer diameter), on the other hand, represents the total width of the O-Ring across its outer edges. These measurements are critical to ensuring you select an O-Ring that fits perfectly in your application without being too loose or tight, which could compromise the seal.
  • Question: How many O-Rings are included in a pack, and is it enough for my needs?

    Answer: Each pack of the 230 Silicone O-Ring includes 10 individual O-Rings. This quantity is often sufficient for most DIY projects or light industrial applications, such as replacing seals in plumbing or mechanical systems. If you have a larger project or anticipate multiple repairs, you may want to order multiple packs to ensure you have a sufficient supply on hand to avoid downtime and maintain efficient operation.
  • Question: Where can I buy 230 Silicone O-Ring, 70A Durometer, Red, 2-12 ID, 2-34 OD, 18 Width Pack of 10?

    Answer: You can purchase the 230 Silicone O-Ring, 70A Durometer, Red, 2-12 ID, 2-34 OD, 18 Width Pack of 10 from Ubuy.
