PTFE vs EPDM
Btrueblood gives an excellent response, id give the same advice. If you want the parts to seal use EPDM or Natural rubber, the PTFE material will not seal well at all. It is harder, yet more durable & certainly more costly but it most likely will not seal as well as an elastomer Hope this...- Kuzmicnr
