Customer Questions & Answers
-
Question:
What is the DERNORD PTFE Teflon Tri-Clamp Gasket O-Ring made from?
Answer: The DERNORD PTFE Teflon Tri-Clamp Gasket O-Ring is made from high-quality PTFE (Polytetrafluoroethylene) material, which offers excellent chemical resistance and durability. This material is ideal for use in sanitary applications, as it does not absorb moisture and is resistant to a wide range of chemicals. This makes the gasket perfect for food processing, pharmaceutical, and industrial settings where hygiene and safety are paramount. -
Question:
What sizes of pipes can the DERNORD PTFE Gasket fit?
Answer: The DERNORD PTFE Teflon Tri-Clamp Gasket is designed to fit a 3-inch sanitary pipe, specifically a pipe with an outer diameter of 91MM. This sizing ensures that it provides a secure and leak-proof seal when used with compatible tri-clamp fittings. It is crucial to match the gasket size with the pipe size to maintain system integrity in applications like brewing, dairy, and water treatment. -
Question:
How does the DERNORD gasket compare to rubber gaskets?
Answer: Compared to rubber gaskets, the DERNORD PTFE Teflon Gasket offers superior chemical resistance and can withstand a wider temperature range. While rubber gaskets may degrade when exposed to certain chemicals, PTFE remains stable and performs reliably. This characteristic makes it the preferred choice in environments where chemical exposure is a concern, such as in food and beverage processing or in laboratories. -
Question:
What are the benefits of using a Teflon gasket in sanitary applications?
Answer: Using a Teflon gasket like the DERNORD PTFE version in sanitary applications offers multiple benefits, including exceptional resistance to high temperatures and aggressive chemicals. This ensures that your equipment remains sanitary and safe. Furthermore, PTFE's non-stick properties minimize residue build-up, making cleaning and maintenance more manageable, which is essential for compliance with health regulations in food production plants. -
Question:
Can the DERNORD Tri-Clamp gasket be reused?
Answer: While the DERNORD Tri-Clamp gasket is durable, it is typically recommended to replace it after each use, especially in high-pressure or high-temperature applications. Although PTFE gaskets do wear less than rubber alternatives, reusing them can lead to compromised seals, potentially causing leaks and contamination. For the best results, use a new gasket each time to ensure optimal performance in your system. -
Question:
Is this gasket suitable for high-pressure applications?
Answer: Yes, the DERNORD PTFE Teflon Tri-Clamp Gasket is suitable for high-pressure applications, due to its durability and high tensile strength. PTFE gaskets can withstand significant pressure without deforming, making them a reliable choice in systems requiring secure sealing under pressure. This feature is particularly important in industries like pharmaceuticals and brewing, where pressure fluctuations are common during operations. -
Question:
How do I install the DERNORD PTFE gasket correctly?
Answer: To install the DERNORD PTFE gasket, begin by cleaning the mating surfaces of the fittings to remove contaminants. Next, place the gasket into the groove of one fitting, ensuring it is seated evenly. Align the second fitting and secure the tri-clamp over both fittings, tightening it until the gasket is compressed firmly for a leak-proof seal. Proper installation is vital to prevent leaks and ensure system functionality. -
Question:
Can the DERNORD gasket be used in extreme temperature environments?
Answer: Yes, the DERNORD PTFE Teflon Gasket can withstand a broad range of temperatures, typically from -100°C to 260°C. This makes it suitable for extreme temperature environments, such as in the pharmaceutical industry where sterilization processes may involve high heat. Its stability at both high and low temperatures ensures that it maintains its sealing capability, preventing leaks in critical applications. -
Question:
What applications are the DERNORD PTFE gasket ideal for?
Answer: The DERNORD PTFE Teflon Tri-Clamp Gasket is ideal for a variety of applications, including food and beverage processing, pharmaceutical manufacturing, and chemical industries. Its durability and chemical resistance make it a solid choice for any system that requires sanitary conditions and reliable performance under varying conditions. Whether you are working with liquids or gases, it's a versatile gasket to consider. -

DERNORD Fittings Editorial Review
The DERNORD PTFE Teflon Tri-Clamp Gasket O-Rings are a mixed bag. While some customers found them to be fantastic for sealing 3-inch tri-clamp sanitary pipes, others did not have a positive experience. Some customers complained that the gaskets were hard, stiff, and did not seal as well as silicone gaskets. There were also mentions of the gaskets being misshapen and difficult to fit into the grooves of the tri-clover fittings. However, there were also positive reviews that praised the gaskets for their rigidity, lack of stretch, and superior performance compared to other manufacturers. Overall, the DERNORD PTFE Teflon Tri-Clamp Gasket O-Rings have both satisfied and dissatisfied customers, with some finding them to be a great value for the money and others considering them useless.
