Reinforced PTFE packing uses high-strength inorganic fibers to make up for the lack of strength of the raw polytetrafluoroethylene film, overcomes the cold flow properties of pure polytetrafluoroethylene products, and also improves the wear resistance. It can be widely used in valves and rotary pumps with anti-fouling requirements, weak alkali, and strong acidic fluids.
Valves Pump Gland Packing Seals White Pure PTFE Gland Packing is a high-performance sealing material designed for demanding industrial applications. Made of pure polytetrafluoroethylene (PTFE), it is chemically resistant and has a low friction coefficient, ensuring reliable sealing performance under extreme conditions. With strong temperature resistance and anti-aging properties, the packing is very suitable for pumps, valves and other rotating equipment, and is widely used in chemical, petrochemical, pharmaceutical and other industries. White Pure PTFE Gland Packing does not contain additives such as grease and graphite, ensuring safety in clean environments, while reducing equipment wear and extending service life. Easy to install and maintain, it can effectively reduce downtime and improve production efficiency.
This PTFE gland packing is designed to provide consistent sealing performance in pumps, valves, and agitators. It functions by compressing around the pump shaft or valve stem to reduce leakage, ensuring operational reliability in chemical, petrochemical, and industrial processing applications.
Manufactured according to international standards, the product exhibits uniform density and precise dimensions, enhancing compatibility with various valve and pump designs. The chemical inertness of PTFE allows for use in corrosive environments, while the low friction coefficient minimizes wear and reduces torque requirements.
This gland packing seal is suitable for the following industrial scenarios:
This packing is compatible with a wide range of chemical fluids including acids, alkalis, solvents, and hydrocarbons, due to the chemical inertness of pure PTFE. It is suitable for both aqueous and non-aqueous media in industrial applications.
The packing is cut to fit the gland chamber, then compressed uniformly around the shaft or stem using gland bolts or packing followers. Proper installation ensures minimal leakage and reduces wear on rotating or reciprocating equipment.
Periodic inspection of compression and wear is recommended. Unlike softer materials, PTFE maintains shape under load but may require adjustment of gland bolts over time. Replacement intervals depend on operating temperature, pressure, and fluid type.

READ MOREIn the vast world of modern industry, sealing technology is a key link to ensure stable operation of equipment and improve production efficiency and safety. Its importance is self-evident. Polytetrafluoroethylene (PTFE), known as the "king of plastics", is unique in the field of sealing packing due to its excellent chemical stability, excellent high temperature resistance and extremely low friction coefficient, and has become the object of favor in many industries. Jiangsu Jintai Sealing Technology Co., Ltd., as a leader in this field, has pushed the application of polytetrafluoroethylene packing to a new height by relying on its profound industry background and technological innovation.
Polytetrafluoroethylene, as a polymer material that is inert to almost all chemical substances, can show extraordinary adaptability under extreme conditions. Its excellent corrosion resistance enables polytetrafluoroethylene packing to easily cope with the erosion of various media such as acids, alkalis, salts, solvents and even oxidants, and is widely used in harsh working environments such as ships, electricity, steel, and chemicals. The high-temperature stability of polytetrafluoroethylene is also extremely outstanding. It can maintain excellent physical and chemical properties in a wide temperature range of -200°C to +260°C, which is undoubtedly a great blessing for industrial equipment that needs to operate continuously at high temperatures.
Since its establishment, Jiangsu Jintai Sealing Technology Co., Ltd. has always adhered to the business philosophy of "technological innovation, quality-oriented" and is committed to the research and development and production of high-end sealing products such as polytetrafluoroethylene packing. The company is located in the scenic Yuanzhu Industrial Park, Taixing City, Jiangsu Province. It has a modern production base and advanced production equipment to ensure that every product can meet the highest standards in the industry. Through years of scientific research and production accumulation, Jiangsu Jintai has not only established a complete quality management manual and monitoring system, but also has a research and development team composed of industry experts and technical backbones to continuously promote technological innovation and product upgrades.
Jiangsu Jintai's polytetrafluoroethylene packing has won wide recognition in many industries such as shipbuilding, power, steel, chemical industry, and machinery for its excellent performance and reliable quality. In the shipbuilding industry, polytetrafluoroethylene packing is used to seal key parts such as various valves and pump bodies, effectively preventing the leakage of seawater, oil and other media, and ensuring the safe navigation of ships; in the power industry, its excellent high temperature resistance makes polytetrafluoroethylene packing an ideal sealing material for high temperature equipment such as boilers and steam turbines; and in the chemical industry, facing various corrosive media, polytetrafluoroethylene packing has shown unparalleled stability, ensuring the continuity and safety of chemical production.
As an important part of modern industrial sealing technology, polytetrafluoroethylene packing is carefully built by Jiangsu Jintai Sealing Technology Co., Ltd., and is writing its own legendary chapter with its excellent performance and broad application prospects.
