PTFE rubber seal is a seal made of polytetrafluoroethylene (PTFE). PTFE is a synthetic material with excellent chemical stability and low friction properties that is used in a wide range of industrial fields.
Cased Spring Seals are the best choice for extreme rotational conditions. In these designs, a metal casing is constructed around the outside of the spring seal, which in turn is press-fit into the hardware hole. Metal-to-metal crimp ensures a tight seal as well as an efficient anti-rotation mechanism. Because these seals are installed in an open bore, they are suitable for rotating applications such as gearboxes and power transmission systems.
Teflon Filled Graphite Spring Energized Lip Seals are sealing elements designed to provide efficient sealing performance in dynamic sealing applications. This type of lip seal structure consists of a metal spring and a lip seal element. Lip seal elements are usually made from a mixture of polytetrafluoroethylene (Teflon) and graphite. This material has excellent chemical inertness and wear resistance, providing excellent sealing in a wide range of industrial media.
Teflon seal ring is also known as (PTFE seal ring). The PTFE sealing ring customized from modified polytetrafluoroethylene material has good properties of water resistance, high temperature resistance, corrosion resistance and anti-aging. It has good resistance to media, solvents and various chemical media at temperatures between -20°C and 200°C, and its operating pressure range is 45-60Mpa.
PTD-External Face Spring Energized PTFE Seals are commonly used in equipment such as valves, pumps, compressors, rotating shafts and pistons in the chemical, oil and gas, food and pharmaceutical industries. They have broad application prospects in applications requiring high performance sealing and corrosion resistance.
Les joints pour câbles et fils ont une excellente isolation électrique et ne sont pas affectés par la température ou la fréquence. Il permet de s'assurer que les produits électroniques ne sont pas endommagés et qu'ils conservent leur étanchéité après avoir traversé l'objet, et joue le rôle d'imperméable et de scellant.
Rotary Shaft Seals in Food Processing refer to rotating shaft seals used in the food processing industry. These seals are used to prevent liquids and particulate matter from leaking out of rotating equipment (such as stirrers, mixers, pumps, etc.) while preventing external contaminants from entering the interior of the equipment. The food processing industry has special requirements for seals as they need to be able to withstand frequent cleaning and disinfection processes and must comply with food safety standards.
Teflon bearing seals are seals made of Teflon material. They have excellent high temperature resistance, corrosion resistance, wear resistance and low friction properties and are widely used in various fields.
High pressure washer rubber seals are essential for various accessories in pressure washers. These include high-pressure nozzles and nozzle heads, pump bodies, high-pressure hose connections, control valve seals, and plunger or piston pumps. Rubber seals ensure proper sealing and prevent leakage in these components. The nozzle head and pump body seals prevent water leakage, while the hose connection and control valve seals prevent leakage. The plunger or plunger pump also requires rubber seals to prevent leakage.
Les joints en PTFE présentent de nombreux avantages, tels qu'une excellente résistance chimique, une excellente résistance aux températures élevées, un faible coefficient de frottement, etc., ce qui les rend largement utilisés dans de nombreux domaines tels que l'industrie chimique, l'industrie pharmaceutique, l'industrie alimentaire, l'industrie aérospatiale et l'équipement mécanique. Bien que les joints en PTFE présentent également certains inconvénients, tels qu'un prix plus élevé, une faible résistance et un coefficient de dilatation élevé, les avantages l'emportent largement sur les inconvénients, ce qui en fait un matériau d'étanchéité très performant et largement utilisé.
PTFE rubber seals have excellent corrosion resistance to most chemicals, including acids, alkalis, solvents, etc. They maintain sealing performance in harsh chemical environments.
PTFE rubber seals have an extremely low coefficient of friction, making them excellent in dynamic sealing applications. They reduce energy losses, reduce friction and wear, and increase seal life.
PTFE rubber seals maintain good performance over a wide temperature range. They are able to withstand extremely low temperatures to -200°C and high temperatures to +260°C.
PTFE rubber seals have excellent compression elasticity and resilience, providing reliable high-pressure sealing performance. They are widely used in equipment such as high-pressure pipelines, valves and pumps.
