The 40L N-type PFA supply tube is used as a set with large-capacity liner bags. Formed in one piece from high-purity PFA, it withstands highly corrosive photoresist chemicals and etching solvents without reacting with the media. Produced dust-free throughout, particle and metal leaching are strictly controlled to semiconductor industry standards, eliminating chemical contamination. A side hole at the top balances pressure, preventing the liner bag from contracting under negative pressure and blocking flow during extraction. The base uses an FKM fluoroelastomer sealing ring for durable, leak-free sealing, and the standardised connector suits automated production lines, meeting continuous transfer needs for medium-to-large volumes of high-purity chemicals.
