● Wetted parts: Ultrapure PFA. ● Nut: Ultrapure PFA. ● Maximum working pressure: 125 PSIG (8.6 bar), see pressure/temperature table. ● Operating temperature range: -18℃~200℃, 1½ and above specifications are recommended to be used at a temperature below 150°C. | |||||||||
● PFA flared end: Made of perfluoroalkoxy resin (PFA), this flared end is formed through a flaring process to create a flared structure. It directly fits over the end of the PFA tubing, leveraging the material’s elasticity to create a seal.
● NPT female end: Conforms to the National Tapered Thread Standard (NPT) and mates tightly with male threaded components (such as valves and equipment connectors) by rotation, creating a metal-to-metal seal or for use with a sealing ring.
● Straight-through design: The axes of the two ends coincide, allowing fluid to pass through in a straight line, reducing pressure drop and turbulence. It is suitable for applications sensitive to flow resistance.
● PFA material is highly resistant to nearly all chemical media (including concentrated sulfuric acid, hydrochloric acid, nitric acid, and organic solvents), allowing for long-term use in highly corrosive environments.
● Suitable for high-purity chemical transfer in the semiconductor industry and strong acid and alkali transfer in the chemical industry.
● PFA material has an operating temperature range of -18°C to 200°C (-0.4°F to 392°F), meeting the needs of high-temperature fluid transfer.
● For example, during high-temperature sterilization processes in the pharmaceutical industry, it ensures that connectors remain deformed and leak-free.
● PFA material’s low permeability reduces the risk of fluid contamination, meeting the stringent media purity requirements of the semiconductor and photovoltaic industries.
● For example, in chip manufacturing, it prevents metal ion precipitation from contaminating critical materials such as photoresist.
● The tapered design of the NPT thread creates a tight fit through rotation, which, combined with the elasticity of the PFA material, creates a double seal, effectively preventing leaks.
● The flared end achieves a seal through mechanical compression, eliminating the need for additional seals and simplifying installation.
● PFA material offers high strength, impact resistance, and abrasion resistance, making it suitable for high-pressure, high-flow piping systems.
● For example, in the chemical industry, it can withstand the impact and vibration of the media within the pipeline.
● Transporting high-purity reagents, corrosive liquids, and high-temperature gases to ensure the stability and safety of the production process.
● For example, connecting equipment such as photolithography machines and etching machines to transfer key materials such as photoresist and etching solutions.
● Transporting corrosive media such as strong acids and alkalis, replacing traditional metal fittings and extending equipment life.
● For example, in the chlor-alkali industry, connecting electrolytic cells and storage tanks to transfer sodium hydroxide solution.
● Transporting high-purity liquid chemicals and solvents to ensure the purity of pharmaceutical production.
● For example, in biopharmaceuticals, connecting reactors and filters to transfer cell culture fluids.
● Used to transport chemicals during the solar cell production process, meeting high purity and corrosion resistance requirements.
● For example, in the silicon wafer cleaning process, connecting the cleaning tank and the pure water system.
● Connecting experimental equipment and transporting reagents such as strong acids and bases to ensure the accuracy of experimental results.
● For example, in analytical chemistry experiments, connecting chromatographs and injectors.
