PFA/PTFE-Lined Valve & Sight Glass

The specific finding a fluoropolymer-lined equipment page should lead with: across all six refrigerants in the Flowline chart, PVDF/PFA/PTFE all rate E while 316SS drops to F — the only family in the 552-row chart where stainless is the weakest listed wetted material against an otherwise benign-looking fluid. Same pattern, less severe, on creosote and tall oil. Moderate because no vendor page in the corpus names Freon service directly; the material conclusion is from the chart and the lined products above are the corpus's matching hardware. Materials to confirm: PFA lining, PTFE, Borosilicate glass panes to DIN 7080, Housing EN-JS 1049, Flowline chart, all six Freons at 40°C/104°F: PVDF E, PFA E, PTFE E — but 316SS only F (Fair), Flowline chart: 316SS G on creosote and tall oil at both 40°C and 80°C; F on olive oil at 80°C. Specific chemicals include Freon-11, Freon-12, Freon-21, Freon-22, Freon-113, Freon-114, creosote, tall oil, olive oil (hot).
