is what was needed
this one is what I was expecting and trying to get - hard to tell the size from the info - but this one fit and works as I wanted it to - it is heavy and feels sturdy

Improved my fermentation process.
Very pleased with the construction and quality of the unit. I am using it on my conical fermentation tank it helps me see the sediment drop and when I can dump it. Well worth the money for me.

Heavy Duty!
This looks and feels like it should cost way more! It is heavy and built solid. The finishing/polishing on the stainless steel is top notch. Pressure rating is 120lbs! I'm very happy with this for my dry hopper.

i have ordered a few of these site glasses in the past and never had a problem, but I did get one that was broken in shipping. And the seller was very quick to fix the problem. They are very well built and work flawlessly

This sight glass is very well made. Very heavy. Works well with my still. Would definitely purchase again

This has come down into the affordably priced zone. Not cheap, but not stratospheric. Very nicely made. It does look like there are silicone gaskets to seal the tempered glass in the housing, which you may have feelings about. My biggest surprise is how heavy this thing is. If you are thinking of in-lining a number of these, you will need to think about the weight. Seriously.

This site glass works great ? WHY only ONE star as i cannot find replacement silicone gasket seals for this unit and for that reason i will not rate higher as what do i do throw away and buy a complete new site glass. i have not been able to locate on manufacture site also, Very poor service ? parts ? for this site glass. If the manufactures can tell me where to find the replacement parts great i would re rate this site glass
