A sealant for industrial applications, PTFE packing is an essential component for those applications that require consistent high levels of performance and the ability to maintain non-contaminating properties while providing a robust seal.
With its smooth surface and low-friction properties, PTFE packing helps reduce wear and tear, leading to improved efficiency, which is vital in rotating or sliding components.
At SSP, we offer PTFE packing solutions in braided, moulded, and cut gaskets, providing you with flexibility and customisable solutions while ensuring optimal performance and sealing.
What is PTFE packing?
Made up of polytetrafluoroethylene, PTFE packing is most suitable for complex applications where mechanical compression is required and where oxidising media or corrosive chemicals are present.
Often referred to as TEFLON, we use PTFE packing when durability and versatility are required to prevent leaks.
When we explore PTFE packet meaning we start with the knowledge that this is one of the most widely used sealing materials across various types of applications.
Used to prevent leaks from liquids and gases and ensure the integrity of the system and application remains intact at all times, PTFE packing is suitable for industrial seals within valves, pumps, flanges, and compressors.
Able to withstand harsh conditions, PTFE packing is designed to prevent leaks.
However, it’s important to note that the use of PTFE packing will depend on the application, industry-specific guidelines, and best practices.
PTFE packing applications
Application of PTFE packing can be found in:
- Petrochemicals
- Textiles
- Paper and pulp
- Power plants
- Chemical industry
- Aerospace
- Food and beverage
- Pharmaceutical
- Valves and pumps
- And much more.
Advantages of PTFE packing
- Resistant to strong chemicals such as solvents, bases, and acids (and still works effectively and efficiently in applications containing sulphuric and nitric acid).
- It has low friction characteristics, which help reduce power consumption, lower carbon footprint, and save money.
- Resistant to corrosion.
- PTFE packing can be made stronger with lubrication and waterproofing.
- It can maintain a tight seal under high pressure and temperature ranges, for example, enduring and remaining stable in temperatures ranging from -200 degrees Celsius to 260 degrees Celsius.
- Helps to enhance the longevity of equipment, reducing maintenance costs and potential downtime.
- It can be cut and shaped to fit various components.
- It is non-reactive, non-toxic, and non-contaminating – meaning it can also maintain hygiene standards.
Types of PTFE packing
PTFE graphite packing – offers chemical resistance and enhanced thermal conductivity, ensuring machinery operates safely and efficiently, helping to support a reduction in downtime. Suitable for pumps, mixers, and all other forms of dynamic applications.
PTFE gland packing – used when you require low friction and high resistance to chemicals. Providing an effective seal for valve stems, pumps, and rotary shafts, PTFE gland packing offers a robust seal without requiring excessive pressure.
PTFE braided packing – a strong, durable seal. The braiding on this packing helps enhance the seal’s overall tensile strength, making it a great solution for high-stress environments. Offering a high degree of flexibility, this type of seal is commonly used in the petrochemical and pharmaceutical industries.
PTFE aramid packing – a composite packing material that includes durable aramid fibres. It is these synthetic fibres that offer abrasion resistance and mechanical wear.
PTFE chevron packing – also known as v-ring packing due to its unique design, this type of PTFE packing can expand or contract depending on changes in pressure on the seal, ensuring consistency at all times. Often used in the oil and gas and aerospace industries.
PTFE fibre packing – in this instance, fibres are twisted together to offer a strong seal that is chemically resistant and offers low-friction properties to reduce wear and tear.
PTFE pump packing – primarily used in pump systems, PTFE pump packing is incredibly versatile and can be reinforced with other materials such as graphite, depending on requirements.
PTFE stem packing – suitable for valve stems and actuators. PTFE stem packing forms a tight seal around the stem, reducing wear on the stem valve through its low-friction properties.
PTFE valve packing – suitable for gate, globe, and ball valves, PTFE valve packing can withstand mechanical forces that are experienced from various valve operations.
When evaluating the various types of seals and gaskets, it is essential to select the sealing solution that is best suited for your specific application, considering the environment in which it will be installed and the performance requirements of the seal.
Industrial sealing
Used for safety and to provide a tight and robust sealing solution, all PTFE packing products must be certified, tested, and quality assured to ensure they can maintain high levels of performance.
At SSP, we’re trusted and valued suppliers of a range of seals and gaskets, helping you find the right and most appropriate sealing solution for your application. Call us today to find out more.
