Replacement sight glass

I would try looking in the yellow pages for places that sell glass for windows. Not that I think they would have any sight glasses, but they are likely to know who does.

Try the manufacturer of the hoist, or better yet, go to the class source,Swift Glass, Corning New york - contact 131 W. 22nd Street,

sight glass - give them the diameter and thickness and I'm sure they can fix you up. They carry Corning, Schott, Pilkington, Maxos, etc.

If you can get dimensions from him, and have him send a sample so you know what the o-ring groove looks like (he should send the o-ring as well), any optician should be able to bang one out for you. That's pretty much what they do all day.

I've purchased several glass rounds from McMaster.

This is not my area, but it looks like something that wants some strong glass -- tempered, or, better yet, borosilicate, as Clare said.

And jeez, Iggy, teach someone how to do a proper job with Teflon tape. That one looks like a gob of spit.

I assumed it was an unpressurized reservoir, and the main risk of breakage is rough handling... I'd have replaced it with plexi in

Anyway, I just checked, McMaster has both borosilicate and quartz in small sizes. I replaced a similar sight glass years ago by hand grinding some scrap window glass on one of little stained glass shaping thingies.

I was thinking Coyote "Engineering."

Yeah, it looks like an unpressurized reservoir, but one that lives in a rough environment.

Applied by an actual coyote. d8-)

These things are NOT terribly expensive, maybe about $10 now. I replaced the ones on my lathe, they were leaky and opaque.

Ignoramus31353 fired this volley in news:a-ednThqd4iPcLzKnZ2dnUU7-R snipped-for-privacy@giganews.com:

Ig, it's just a sight glass! If it isn't pressurized, you could make one yourself from darned-near any transparent material that would take the heat of the fluid.

If you can't get one anywhere else, I'm betting the optics department of Fischer Scientific will have exactly what you want.

Since we're giving Iggy thread advice, let me add this: I sometimes have a taped joint leak. I never have a leak on a joint where I've used "paste" sealant. With PTFE or Teflon.

I sold that hoist, I did not make it or set it up.

Teflon tape works great for me.

So does the goop paste.

Years ago I added larger diameter gas pipe in our house. I asked what sealant to use on the black iron pipe and was told to use the yellow teflon tape. EVERY joint leaked. By the time I got to testing for leaks the next day a bunch of the pipe had been framed in because we were remodeling part of the house at the same time. So I had to unscrew pipe that obstructed by all sorts of framing. GRRR. I then called the gas people and they said "Rector Seal". No leaks with that stuff. Kinda goopy but seals way better on crappy black iron pipe threads. Eric

I've seen plenty of paste sealant joints leak whether done by myself or professional gas fitters on various pressure systems including low

Teflon IS PTFE.

Of course they should be checked, that's how I knew every joint I made with teflon tape on that crappy black iron pipe leaked, and how I knew none leaked when I remade them with the paste. Only a fool would assemble a joint that's supposed to be leak free and not test it.

Eric

How many layers did you put on? As the size of the pipe increases, you need more layers. With 1-inch pipe, I use three layers.

I hate the goo factor of the paste, but it seems way less likely to leak than the teflon tape. I've switched.
