To transport low-pressure hydrochloric acid, why use rubber gaskets?

It should be a PTFE gasket, corrosion-resistant and good sealing: lol
The transportation of low-pressure hydrochloric acid often uses hard PVC, PP or steel-lined PO, fiberglass and other materials. It should be said that soft rubber sealing gaskets are the best choice because they are corrosion-resistant, low-cost, and have good sealing effects. However, PTFE gaskets are rarely used. The PTFE gasket is too alkaline and the flange screws need to be tightened very tightly to achieve a good seal. The materials of the above-mentioned low-pressure hydrochloric acid pipelines are generally not suitable for flange bolts that are too tight, which may cause damage to the flange.
Hydrochloric acid pipelines generally use rubber-lined iron pipes, which are easy to seal with rubber gaskets.
