Sight Glass Material

[SAMPLER]

I'm looking for some sight glass material and was hoping to pick up it locally. I have Grainger store right around the corner from the house and was hoping I could pick it up there.

Anyone have an idea if they carry what I would need? Sorry if this a duplicate thread.

My worry would be the 250deg heat limit depending on use, if it's for a mash tun or an E-kettle it should be fine, but if it's a direct fired kettle I'd be worried about the heat coming up the sides and melting it. I believe most use a borosilicate glass.

I just use a piece of silicone tubing on a 1/4 inch barb. its translucent and takes up to 500* heat. just find a way to attach it. make a note tho that i do this on a 10 gallon water cooler, so your application may not allow for this.

Two out of my three are the long part of racking canes that I broke trying to wrestle the tubing off for cleaning.

I have used those on A 250 HP boiler that ran at 120 PSI. The hardest part was the swedge style couplings, The glass needed to be just long enough to fit inbetween the swedges then centered to tighten. Cutting the glass to length isnt that hard with the cutter and some time. I work with A couple of guys from the old oly brewery and they said many of there tanks had glass site glasses, but I dont know there aplications.

I currently work in A USDA enviorment, and glass is A big NO NO. So lexan and whatever other proudcts available are used whenever possible.

Why is glass a no no in USDA?

 

[cincypilot]

A guess would be if it broke glass everywhere!

I am planning on using these on all three kegs and will be using some extra copper tubing as protective tube. I had thought of using high temp plastic tubing but I would be prefer a rigid tube for this application.

Glass is nearly impossible to detect in A proudct. It fragments into peices, where as plastics and rubbers just tare. A friend of mine worked for pepsi, And after his time there he refused to drink sobe, I guess that under the filler it was A razor blade factory full of shards. I noticed the other day that the new sobe bottles are plastic now. PLEASE dont get me wrong, Im not saying that theres A problem with glass in proudcts, its just restricted to the fiewest areas possible to keep it from becoming A problem thats all
