Bonding PFA: epoxy? plastic welding?

Bonding PFA: epoxy? plastic welding?

Bonding PFA: epoxy? plastic welding?

(OP)
Hello,

I have some flexible tubes of PFA (1/8" OD 1/16"ID) that I need to bond to a larger PFA tube (rigid). I was wondering what was the best way to do that. I just ordered some epoxy for PFA and I was also looking into plastic welding. What would be your advise on the best way to do that? The assembly will go to a pressure of ~3bar.
If plastic welding is a good option, which kit do you recommend me to buy? I am willing to put up to 400$ in that thing.

I also need to do the same stuff but with PTFE. Now PTFE will be more annoying as it does not really weld and does not really stick. The adhesive I ordered is also rated for PTFE (treating agent + epoxy), but I wanted to know if you had any good options for me to consider. Same dimensions

Thanks a lot!
