1) Try a spare screw (if yours came with one). I have one Kayfun where I tried 3 screws, and only 1 of the screws slowed it to a very slow seep but didn't stop it entirely.
2) Wrap your screw threads with a very small strip of plumber's tape after filling. Will definitely stop the seep, but you will need to do this every time you screw / unscrew the fill screw.
3) Use a tiny o-ring. Will stop the seep, but even the smallest of o-rings will not allow the screw to go in flush, so you will not be able to get the Kayfun to sit flush on a mod. And actually, it may sit a little cockeyed. I tried the little o-rings that are used to seal the fill screw on Kir Fanis trap / angel tanks, and these also: 002 Buna-N O-Ring, 70A Durometer, Black, 3/64" ID, 9/64" OD, 3/64" Width.
My KFL came from SvoeMesto's shop. Came with no spare anything. My screw was leaking over time, so I put a small wrap of teflon tape around the screw threads. Hasn't leaked since.
I do not have a pic at the moment, but plumber's tape / Teflon tape is very, very thin and has no adhesive. Just cut off a teeny sliver and it will self-adhere to the threads of the screw as you place it on there. The screw will still go in no problem - as easily as without the tape. Let me know if you have any other q's - I'm on mobile at work so sorry if this wasn't exactly thorough
FWIW - when you pick up the tape and see it, I think it will all make sense!
HAHA, please don't let a plumber see how you did that. Typically you sort of roll the screw onto a small strip of tape, whose width is the length of the threaded section of the screw. So, TINY for this application. But hey, if that works, then great!
Glad I read this thread. I have recently received a kayfun lite, and all the spare fill hole screws that came with the package are leaking. Not that the leaking is severe, its more just an ocd kinda thing. Is this plumbers tape the same as teflon tape? Are they available at a hardware store?
Yes and kind of yes! ANY hardware store, even the little local ones will carry this. And technically, plumber's tape and teflon tape are two different things, although the words are commonly interchanged. You want 'plumbers tape' or 'thread seal tape'.Is this plumbers tape the same as teflon tape? Are they available at a hardware store?
Not at all. Plumber's tape is made of PTFE which is inert.Another quick question. Do you think that the suggested tape would have any negative reaction to ejuice?
