3/4" MPT 6" Long Sightglass Tubes FS

I picked up some polycarbonate tubing to make sight glasses and have some left over if anyone is interested in a flow through sight glass. I made one version that is 6" long and has 3/4" MPT connections on each end or can make longer ones if needed.

Here's the bare tube



Here it is rigged up as I will be running it to oxygenate after boiling and cooling and during mash recirculation to observe clarity



Any questions or requests let me know.
$15 shipped USPS.
Thanks,
Walter

Interested in one. What's the temp rating of this? What's the ID of the tubing?

Jon,
It is rated to 250* and is 3/4" id with 1/8" wall thickness and FDA approved. It's the same material that most of the level sightglasses are made of that you see.

I think you meant 3/4" OD. How are you getting a seal on your O2 line going into the fitting on the left? Pressure fit on female threads? I've done a few of these with a compression fitting to bring the oxygen in. The only trouble having the stone extended all the way into the clear tubing is the restriction you get.

Bobby, Once I get everything done it will be a swagelok 1/4" tube x 1/4" mpt adapter that seals up my O2 line into the tee.

That stone is about 1/2" and the tubing isn't even sealed to the reducer bushing as I was just mocking up for pictures and I didn't have the right swagelok adapter on hand.


The stone in the picture is the one I use for carbing kegs. Since the stone that I will be using for aerating is a little bigger than 3/4" it doesn't fit into the tube, but stays back in the tee fitting.



I'll get my swagelok adapter bored out as that will be what seals everything up and get mine all put together.

I have a few of these made up if anyone is interested. They are a nice way to monitor mash recirculation for clarity.

Is the 15 shipped for the treaded poly tube only?

Yes, just the threaded tube. I was working on different aeration layouts in the second photo.

I'm interested. please pm me with pymnt info
