Options/Suggestions to add a sight glass to my Rims?

[homebrewdude76]

I kill my RIMS element after I stir or disturb the mash, then turn back on when its "clear"

This is my RIMs tube on a 21gal kettle, any suggestions to add a sight glass that can hold up to the weight of the RIMS?

I have this style on my chiller, maybe that is good enough?
