Default Plate chiller fittings

Do you guys Teflon tape the fittings on your plate chillers? I have been reading a lot about guys putting the chillers in the oven and was just curious if they re-tape them every time.

No need to retape. The tape is more about lubricating than sealing.

So just leave the fittings on? Do you put your chiller in the oven, Bobby?

I haven't yet because I haven't noticed any flow rate issues and I suppose my hot water backflushing has been doing all the work just fine. I do plan to bake it soon to see what else comes out though. I will leave the fittings on.

Yeah, I don't have any flow problems, but I did get an infection in a batch so now I am just trying to get everything cleaned up. I boiled it in oxy, flushed it fwd/bkwd, and had some chunkies come out. Not a lot, but definitely had chunks. Debating if I want to put it in the oven now, too.

Heat sanitizing is how I deal with the potential of junk being in the chiller. At flameout, the 0min hops (bagged of course) go into the kettle and I start recirculating wort through the plate chiller back to the kettle with the coolant turned off. I usually clamp the bag to the side of the pot since I haven't gotten around to building a hop spider yet and put the outflow of the recirc into the bag for force contact with the new hops. 3-5 minutes later, I turn the coolant water on and when the outflow reaches 68F, I redirect to the fermenter.

I understand there are some organisms that can survive it, but I'm pretty confident that 3-5 minutes at 208F is enough to nuke most things that we're worried about like Aceto/Lacto.

All the stuff you have built, and you don't have a hop spider yet?

I do the same process at the end of my boil. I am pretty sure the infection came in somewhere after the fact, but I am trying to eliminate every possibility. It was only my 4th batch so I am not too surprised that I screwed something up. Just don't want it to happen again. I'd like to move on to kegging soon so I can eliminate the bottle infection possibility.

You ever see a carpenter's house? Falling apart.

Just to let you know.. 500* for an 2 hours, then left in until it was cool, and the tape didn't melt. so guess it's not a big deal to leave on.
