Finished my projects. I'm getting a leak in my ball valve. Can anyone tell me if thread tape will fix it?

Perhaps you could loosen and very carefully re-tighten the weldless fitting, paying special attention to the o-ring. I've had similar problems in the past with those kind of fittings - a little trial and error always seems to fix it.
Agreed. On all of mine, I had to tighten the hell out of them. Your o-ring doesn't look nearly flat enough.Yuri_Rage said:In that case, teflon tape is definitely the way to go. Pipe threaded fittings can be finicky. Use plenty of tape (very evenly applied), and tighten it down quite snug. That should fix it.
horhay said:Cheese,
your system looks good.your leak problem may be your weldless fitting,try tightening some more.If that leak continues apply teflon tape to threads of fitting,
npt threads (National Plumbing Taper)are tapered threads and require threads to bottom out to seal if no sealant is applied

They do, I had saved a link someone posted once, you won't need to buy any for a long time...comes in a 50 count. These claim to be hi-temp silicone but are black???Cheesefood said:Wrapped the threads in thread tape and tightened it all back up, but I think I destroyed my O rings in the process. Do they sell the high-temp ones at Home Depot? I have a Grainger right by my office if it's cheaper to get them there.

If it's food grade plastic, I'd get stuff that was tight to the CFC and then heat up the other side and expand it to fit.
Does that look anything like this?Cheesefood said:I'll look into getting a M2M adapter and another piece of hose.
