I have one of the 5+ G Speidel Fermenters and would like to add either a thermowell for a "deep probe" or even simply a "grommet" that would allow me to insert my turkey fryer thermometer into the top few inches. I think either will work well.

Any creative ideas? I'm looking at going down through the large plastic cap. I'm not sure if I could drill a 2nd hole in the stopper to make that work. Don't have lab cork borers available any more.

Guess I'm thinking there must be some sort of grommet I can fit to the cap.. or some sort of stainless item that has an o-ring that can be tightened around either the thermowell or even the turkey thermometer?

All thoughts welcome.. thanks guys n gals.

If it's just a turkey fryer thermometer, why not just tape it to the outside or better yet, just get a fermentometer strip and stick that to the outside?

Drilling holes and dropping probes just sounds like you're opening the path for possible infection.

I have an eBay C* thermometer with a probe on a wire.. I have taped that to the outside under a piece of closed cell foam.. that's not bad. I have a strip fermometer stuck to the outside.

Two problems with both of those..
1. If I try to raise the water level around the fermenter.. both the strip thermometer and the ebay thermometer would either be under water or with the ebay unit.. would likely be above the beer level.
2. The plastic, IMO, will insulate the thermometer from the real beer temp.. I'm really getting to the point where I believe the temp inside during active fermentation is hotter than my strip therm shows.

But, thanks for the thought..

I put a 12" 1/2" NPT thermowell using weldless techniques. So I got 2 silicone o-rings and a lock nut with the groove in it, and put one on top and one on the bottom and just tightened it up.

Hope that helps.

So, did you already have the thermowell and bring it to the place for the fittings?

What size thermowell is it? 1/4" ID or ??OD

The thermowell is 1/4" ID, I took my temp probe from my STC-1000 and made sure it fit snug in the thermowell and purchased the thermowell from those guys.
