Yes and it's also pvdf.. which will work for gear containing less than 20% bb.. for gear from best compatibility to worse:
PTFE
NYLON
PVDF (LAST RESORT)

Didn't know this, thanks. I've never gone over 20%, would there be another reason to switch to PTFE? I've used all three and didn't really notice a difference between them.

I spent my childhood in ill fitting yard sale clothes and being the "second shopper" at the grocery store to get around "1 per customer" discount limits.

What was a kind of humiliating experience as a kid turned out to be good preparation for later, when I discovered that behind closed doors, while my wealthy employers/mentors appeared to spend extravagantly, behind closed doors valued and practiced the art of "squeezing a dollar out of a quarter" on every purchase they made.

Try your luck on ebay:

Im not saying they won't work but for the charts I looked at it's marginal.. bets to use ptfe they are best rated across the board. These are great at 1$ a peice

Odd. My SSA package has also been sitting in LA since 12/19 and it also moved towards my direction just now. Maybe you are next

 

[MissedArmDay66]

I have used those before and they did ok but I used some the other day and they turned the dope cloudy.. I want to stress use ptfe ot nylon for gear. Pes for peps

They are from a completely different manufacturer than you mentioned in your post

I know brother I was just giving my insight. After all you guys said use PTFE thats all I use now. Those pekybio and celltreat are great! Fucking Ghoul has me buying shit left and right. When I think something is good he comes out with something better and makes my head spin!

Yeah I switch em out at 40-60 ml just for peaice of mi d myself

 

[Ghoul]

Main reason I choose Supor vs standard PES is the lower protein binding to minimize
peptide lost in filtration (it's small either way, but less is better).
