FKM
Fluorocarbon rubber (FKM) is a mixed polymer made from highly fluorinated hydrocarbons. This ensures very good media, ozone, aging, temperature and chemical resistance. Due to its composition and the manufacturing process, the material is significantly more expensive than EPDM and TPE.

Stainless steel (AISI 304)
V2A (1.4301, AISI 304) is an austenitic, acid-resistant 18/10 Cr-Ni steel which, thanks to its low carbon content, is intercrystalline resistant after welding even without subsequent heat treatment.
