Rubber Stopper Weldless Thermometer

[randyisrad]

I posted a couple days ago that I was going to do a weldless thermometer using a $0.89 rubber stopper and I received a crapload of mockery. You all asked me to post pictures...so you could mock, you asked me to youtube it...so you could mock. Well...in the imortal words of Run DMC:
"But see ahh, ah that's the life, ah that I lead
And you sucker MC's is who I please
So take that and move back catch a heart attack
Because there's nothin in the world, that [Randy]'ll ever lack"

I like the frugality, but is that rubber ok to be in contact with boiling wort?

If its SBR then its rated to 180 and can impart a flavor. Same type of rubber in tires. Synthetic rubber. I would suggest boiling it in a cup or so of water in the microwave, letting the water cool and smell/taste it before investing a batch of beer.

McMaster sells silicone stoppers that are rated to 600 degrees.

Otherwise, this looks like it will work.

No boiling. Just for the MLT and HLT. The rubber is rated up to 230* and the hottest liquid it would be in would be 180-190
