My other sight glasses are too short and wont allow me to fill the kettles to my liking. I grabbed some adapters to go from 1/8" mpt to 1/2" fpt to accept these sights.

Does this have a temperature rating of 220 Deg F for installing on a keg kettle? Also I see the replacement glass (Item #MT520A) is more than the base item? What is the difference between the two items, (#MT521 and #MT520A)?
David K on Feb 26, 2018
BEST ANSWER: Absolutely, this item is designed to be used on a boil kettle. The difference between #MT521 and #MT520A is that one comes assembled with the smaller parts needed and the other comes with just the replacement tube that costs more without the package deal.
So, is the interior diameter 1/2"?
karen p on Jun 29, 2019
BEST ANSWER: Yes. The ID is 1/2". The tube on mine cracked a little over the o-rings before I had a chance to get the tube warm. A hose clamp sealed it up.

Oversized
The description doesn't actually say the diameter of the sight glass anywhere. I expected that it would be 1/2" OD like the typical sight gauges used in homebrewing. Instead I received a massive 1/2" ID tube that doesn't fit the sight gauge I was replacing. Also, you won't maybe need a hose clamp to keep it from leaking. You absolutely will need something to clamp it in place, because the tube was still way wider than the post. Those o-rings are useless and will only serve to make you think you're getting something useful when you see the pictures on here.
