In the world of fluid handling systems, choosing the right gasket material is crucial for ensuring the integrity, performance, and longevity of the equipment. Custom gaskets are made from various materials, each with unique properties tailored for specific applications - each having advantages depending on factors like temperature, pressure, and chemical exposure. In this blog, we’ll explore some of the most common gasket materials used in pump and fluid systems, including PTFE, graphoil, Teflon, rubber, urethane, carbon fiber, flexitallic spiral wound gaskets, and Viton, helping you make an informed decision for your next project.
PTFE (Polytetrafluoroethylene) is one of the most commonly used materials in gasket manufacturing, known for its excellent resistance to chemicals, high temperatures, and wear. PTFE tape and PTFE thread seal tape are popular choices for sealing threads in piping systems, offering a reliable and non-toxic seal. Blue Monster PTFE tape is a popular brand trusted for its high-performance sealing capabilities in pipe connections.
It is a thin, flexible material that creates a leak-proof seal when wound around threads, commonly used in plumbing and pipe installations. It helps prevent leaks by providing a tight seal on threaded connections, particularly in fluid systems that involve harsh chemicals or high temperatures.
Simply wrap the PTFE tape around the male threads of the pipe or fitting, ensuring the threads are fully covered without over-wrapping. This will help prevent leaks and enhance the overall integrity of the seal.
For gasket applications, PTFE provides an ideal solution for sealing, as it is resistant to most chemicals and can withstand temperatures from -200°F to +500°F. PTFE gasket material is commonly used in applications such as chemical processing, food and beverage, and pharmaceutical industries, where contamination-free and durable seals are critical.
Synthetic fiber gaskets are made from man-made fibers, often designed for applications where elasticity, strength, and low-cost material are essential. Some common types of synthetic fibers used for gasket manufacturing include aramid, fiberglass, polyester, and nylon.
5 Examples of Synthetic Fiber Types:
When used in gasket manufacturing, synthetic fiber gasket materials are often combined with other materials like rubber or resin to improve their sealing capabilities and ensure a more robust solution for fluid systems.
Graphoil is a combination of graphite and oil, creating a flexible and heat-resistant material ideal for high-temperature sealing applications. Graphoil gaskets are widely used in high-pressure systems, particularly in the oil and gas and chemical industries, where extreme conditions are the norm. The graphoil gasket material is non-corrosive and provides excellent sealing capabilities even in the most challenging environments.
Teflon, often associated with its brand name PTFE, is a key material in gasket manufacturing, known for its excellent chemical resistance, high-temperature tolerance, and low friction properties. Teflon gaskets are commonly used for sealing in chemical processing, oil refining, and pharmaceutical applications.
Teflon gasket material is ideal for sealing applications where other materials might degrade due to exposure to aggressive chemicals. It provides a tight seal in applications where flexibility and resistance to chemical attack are necessary, especially in critical systems like centrifugal pumps used in fluid handling systems. Centrifugal pumps, which are commonly used in industrial fluid transport, require gaskets that can withstand harsh chemicals, high pressures, and extreme temperatures—making Teflon gaskets an ideal choice for such systems.
Teflon gasket tape is another form of Teflon used for sealing threaded connections, often in applications requiring fluid-tight seals.
For those asking, is Teflon safe?
Yes. Teflon is safe when used as intended, particularly in fluid handling systems, where it provides long-lasting, safe, and efficient sealing performance.
Rubber gaskets are a popular choice due to their flexibility, low cost, and good sealing properties. These gaskets are commonly used in low-to-medium-pressure applications where chemical resistance and high-temperature resistance are less critical than in other systems. Rubber gasket materials like Nitrile and EPDM are often selected based on their compatibility with oils, water, or gases, and are often used in charge pumps for systems that handle water, sewage, and chemicals.
In charge pumps, rubber gaskets help maintain consistent pressure and ensure a reliable seal, contributing to the efficient operation of fluid handling systems.
Urethane gaskets are known for their toughness and abrasion resistance, making them a go-to option in applications where wear and tear from moving parts or abrasive fluids are a concern. Custom urethane gaskets are often fabricated for positive displacement pumps used in high-pressure and high-wear environments like oilfield services and water treatment systems. Urethane’s durability makes it well-suited for handling the stresses and demands of positive displacement pumps in a variety of industries.
Urethane gasket material is flexible, allowing it to conform to uneven surfaces, which improves the sealing performance in critical applications.
Carbon fiber gaskets are made from woven carbon fiber materials and are known for their strength, lightweight properties, and high performance under pressure. Carbon fiber gaskets are commonly used in industries like automotive, aerospace, and high-performance machinery.
It is a composite material made of carbon atoms bonded together in a crystalline structure, offering excellent strength-to-weight ratios.
Carbon fiber strain and carbon fiber wrap are also used for reinforcement in high-pressure applications to enhance gasket performance and ensure a leak-proof seal.
Flexitallic spiral wound gaskets are made from alternating layers of metal and graphite or other soft sealing materials, offering a highly resilient seal for high-pressure applications. These gaskets are often used in power plants, chemical processing, and other systems that require reliable sealing at elevated temperatures and pressures.
Flexitallic spiral wound gasket thickness can be customized depending on the specific needs of the system.
Viton gaskets are made from FKM (fluorocarbon) elastomer, offering superior resistance to chemicals, oils, and high temperatures. Viton gaskets are commonly used in high-performance fluid systems where other materials would break down, especially in oil and gas or pharmaceutical applications.
Viton O-rings and Viton gasket materials are often used for sealing in extreme environments where high thermal resistance and chemical stability are needed. For example, Viton O-rings are designed to withstand high-temperature environments while maintaining excellent sealing properties under pressure.
Choosing the right gasket material is crucial for the optimal performance of your fluid handling systems. Whether you’re looking for PTFE tape for thread sealing, rubber gaskets for flexibility, or Viton gaskets for chemical resistance, understanding the properties and applications of each material can help you make an informed decision. By selecting the right gasket material, you can ensure long-term reliability, efficiency, and safety in your system.
