Afst series connector is designed for high purity semiconductor applications, also suitable for ultra pure or corrosive chemicals. The use of imported materials processing to ensure complete cleanliness ultra joints, can maintain good dimensional stability and resistance to corrosion between -40 ℃ to 200 ℃. And has good mechanical characteristics, abrasion resistance, anti-aging properties, anti-ultraviolet, β and γ radiation, high insulation and dielectric properties. Installation is simple, reducing system complexity and cost. Connector Specifications: 1/8 & amp; quot; -1 & amp; quot ;, connector types: straight, 90 ° elbows, tees are three joints materials are (PTFE, PVDF, PFA, FEP) four kinds, depending on the process and Technical requirements for the different types of connectors selected. Afst fittings have a solid connection, high pressure capability, temperature, sealing and repeated good, easy installation and maintenance, safety and reliability. The product is PVDF (PVDF) material, has excellent resistance to creep and fatigue resistance; and has excellent chemical resistance (all common solvents, acids and alkalis), long-term adaptation highly corrosive gas, liquid environment, no reaction, no distortion, no aging, in a wide range of temperatures all have excellent mechanical properties, temperature ≤200 ℃, pressure 4-8kg. Can be reused, without replacement card sets, liners, excellent air tightness and mechanical properties, complete specifications, applicable to Φ8, Φ6 trachea, is a very good product suitable for gas analysis systems and liquid analysis systems.
