1.5" Tri Clamp Sanitary Sight Glass End Cap 1 1/2" Ferrule Tri-Clamp Acrylic Optically Clarity By Machining Flat Plate. EXTRA THICK!

The media could not be loaded. I had a clear conical and enjoyed watching fermentation occur so when I saw this I thought it might be a good add for my Spike CF10. It is high quality and allows me to both watch fermentation and watch the cleaning process too. Highly recommended.

This is NOT glass nor pyrex. Cheap plastic.

Cracked after one use.Update: same crap. Cracked. Will not be buying any more plastic glasses. Even sounds like junk. Plastic sight glass. Don't buy these, get a steel & glass sealed kind. Be safe.

This seals fine and has been fun to experiment with but not yet sure I'd trust this in place of a stainless cap or other sanitary fitting for longer term contact with beer or when using high temp caustic. Still looking for a great use case for this.

We use this for a degassing chamber, and it comes at a fraction of the cost of other flush mount tri-clamp sight glasses.

Complete garbage it blew out during a run so dangerous not cool at all you will kill your self with these do not buy if u knew how to go about it I would attempt to file a law suit over false claims

Hand tightening down my tri clamp and I cracked my brand new site lens when I hadn't even started to put any pressure on it yet. It has to be somewhat tight to not leak under pressure so I needed to tighten it down a little bit. Plus I don't like the way it protrudes higher than the top of the clamp making it vulnerable to breaking

Ive bought several of these and the 1.5” ones are very different from the other sizes(different manufacturer?) and these fail! Get glass or polycarbonate these acrylic ones are cheap substitutes and will not hold 150psi!!! Failure at 30!!! safety hazard!
