Not sure if everyone has noticed but while i was searching for stainless needle valves for my valved reflux i noticed they were all PTFE seated. I know that this forum frowns upon plastics so thought id let you all know. Maybe i have missed something but still concerned about buying them. Might go with the treated brass option. Let me know what you all think.
Thanks
