Junkosha Fluid Transfer Tubing

Fluoropolymer Tubing

Junkosha Fluoropolymer Tubing offers excellent chemical resistance, heat resistance, and cold temperature resistance. In addition, our High Barrier PFA Tubing uses high-purity PFA for the inner layer construction and barrier fluoropolymer for the outer layer construction. Our High Barrier PFA Tubing is ideal for chemical liquid piping because this barrier fluoropolymer used for the outer layer significantly suppresses the permeation of chemicals such as hydrochloric acid in comparison to conventional PFA tubes.
