Where can I buy or customize 6mm PTFE ball valves?

DN6 is too small; those lined with PTFE aren’t that small. I’ve never seen pure tetrafluorine either
Then just use a needle valve; if you need a ball valve, this one is too small
Swagelok SWAGELOK 6 mm ball valve, standard product, PTFE seal, stainless steel construction.
For such a small diameter, ball valves are not as practical as single-seat valves; there are likely many options available for single-seat valves, and we can also handle them
No need for fluorine lining for the 6-piece version； There are water pipe valves made of pure copper (red copper), which perform better than those lined with fluorine. Be careful when purchasing; some valve balls are made of cast iron, while others are made of stainless steel. Using those made of stainless steel is sufficient
Thank you all! One fluid is corrosive, while the other is prone to decomposition. It’s hard to choose!
Reply to 5# wow0011: Single-seat control valves are suitable only for applications with strict leakage requirements and a small pressure difference, involving clean media. My media consists of one corrosive liquid and hydrogen peroxide – is it possible to use such valves in these cases?
Using fluorinated lining is no problem, but if there are factors such as temperature or high pressure, you can choose a different material. I’m talking about the fluorine-lined single-seat version
You really need to use me to give you a manufacturer, Hamilton
