Default Pyrex glass lens for Swift Lubricator

Does anyone know of a supplier for the "nickel" sized "glass" or Pyrex operational viewing "lens" for the Swift displacement steam lubricator? I have two on my 15 hp Case and both are broken and have nickels in them so they can be used. I had one made at a glass shop and it blew out right away. Maybe they used the wrong material, but with two gaskets, front and rear, it has to be fairly slim.
Thanks,
Gary

Chances are that the 'lenses are just that - lens shaped for strength. Flat glass may not be strong enough. Also - was the one you had made perfectly smooth on the rim? glass is funny stuff - the slightest imperfection will spread like a fire under stress. what kind of gaskets are they? if the material is too hard, it can cause fractures when heated.

Andrew,
I had the distinct honor to be on my Case when both original glasses broke, on different days however. The gasket material is not rubber, I don't think, but kind of a pliable material. They had both worked "forever" and I never tightened them. I found out what the material was after the glass lenses broke. They were both flat glass. Maybe being 96 years old had something to do with it?

I had a gauge glass supply company cut some flat glass for my Swift lubricators some years ago. I sent them a sample and they furnished me with exact copies, which I installed and have used without incident for some years.

Here is the link to their web page:

The replacement glass was high pressure and the thickness was the same as the sample I sent. I imagine they cut the glass to size from glass bar stock that they have.

Gary, did you ever find some replacement "nickel glass"? I have a couple Swift lubricators and I want my 10 cents back.

Jeff Smith, I saw you were also looking for some glass. Did you find any?

If I have to order some I can get extra for anybody who needs it.

Brad,
Between my work, our local club having a "divorce", my engine moving to Silver Creek near Helena and Mike leaving for a year, I put this on the back burner. I would like them. If you want to add me, I'd like two and should get three? Any idea$?

McMaster_Carr carries Pyrex round windows. I ordered some for the oiler on my Ajax. They come in varoius sizes.

Keith, were the parts you ordered "nickel glass" size? I haven't seen anything on McMaster smaller than 1" diameter.

Go to http://www.ernstflow.com/eindex.html , and follow the links to "glass", and to "circles". They will cut whatever size and thickness you want, they even have a table for safe working pressures. They are who I used for my Swift's Sight Feed, 3/16 thick x 13/16 diameter.
