Replacement sight glass
I sold a customer this hoist, and, unfortunately, upon delivery the
sight glass was broken. Here are some pictures: http://igor.chudov.com/tmp/Sight-Glass/ He says that it is a round glass with a little groove for a o-ring. My question is, where can I buy him a replacement glass, any idea? McMaster seems to have complete assemblies only? |

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. |

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. Lloyd |

I never have a leak on a joint where I've used "paste" sealant. With PTFE or Teflon. Bob 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 |

With 1-inch pipe, I use three layers. 3 layers. The guy at the store selling the pipe said that would do it. I asked because the threads were so ****ty. They were very sharp and torn, like they were cut with a dull die set. I think the sharpness just cut through the tape. Whatever the reason the goop is all I have used since and I have had zero leaks since. With brass and bronze and stainless fittings I have never had problems using tape, but the black iron pipe sold around here for gas service sucks. The threads always look like crap. Eric Yeah, I've had some pipe like that, both water pipe and gas pipe. The water pipe is taken care of now -- I'm all-plastic except for some ancient cast iron waste pipe -- but I had some that tore the heck out of tape. On those, I used one of the pasty goos. -- Ed Huntress |

Using teflon tape on these threads virtually always compromises the seal, whether it makes them easier to take apart or not I don't know - but it generally DOES make it necessary. |

Eric They don't call them "dry-fit" or "dry seal" threads for nothing. Using teflon tape on these threads virtually always compromises the seal, whether it makes them easier to take apart or not I don't know - but it generally DOES make it necessary.

These gkasses are readily available from several sources - several of which I have posted. If the OP has me "plonked" and therefore isn't getting the information I guess it's his loss. |

Eric Virtually every brass pipe thread fitting I have ever used was NPTF. Steel and iron pipe are a different story. Using teflon tape on an oil pressure switch that needs to ground a small signal current almost guarantees a failure of the switch function. On sensors that depend on ground through the body of the sensor, same problem.. These switches and sensors have always been NPTF in my experience., along with the "weatherhead" fittings used with them. |

Why would anyone bother to grind a groove in glass? Cut or grind a glass disk (or find a crafts-store and look at the little round mirror selection), use a bit of cork gasket, and you're good to go. |

What you REALLY want is borosilicate (or Boron) glass. However, on most cases you can even get away with a lucite type plastic, at least for a couple years untill it yellows too much. But the right part is available at a reasonable cost. |

Cut or grind a glass disk (or find a crafts-store and look at the little round mirror selection), use a bit of cork gasket, and you're good to go. There are several designs - inclusing one that takes an "O" ring around the circumference of the glass, in a groove, and one that sits against an "O" ring and is held in by another "O" ring between the glass and a clamping plate. There are also glasses that are held un by a threaded ring |

Here are some pictures: http://igor.chudov.com/tmp/Sight-Glass/ He says that it is a round glass with a little groove for a o-ring. My question is, where can I buy him a replacement glass, any idea? McMaster seems to have complete assemblies only? http://www.escopro.com/ |
