Is there a good place to get these sight glasses? I have one that is loose and won't tighten. - Roscoe.

Agco had them a few years ago. They take an o-ring to tighten and seal. ------------- When someone tells you Nothings Impossible, Tell them to slam a revolving door |

Glass threads are stripped. I'll check AGCO. Thanks all, Roscoe.

Here's what I have found with the sight glasses over many years of work on equipment. In the picture the ones on the left are GM #12475420, they were used for radiator sight glasses in heavy GM units. The problem with those is they are plastic and over the years they turn white, the replacement has a brown color to it and seems to last longer. Problem with that is hard to see light oil in it. The middle ones are AGCO #70265359, glass but the threads do go bad if over tightened. The one on the right are Case/IH # 427708C1, same as AGCO, mostly found in school bus units. All of them have the same threads, I like the plastic ones to have around in case I break one or one falls out in the field. Glass is the best for visibility but the plastic has more threads. |

| It doesn't take much for tight to keep them from leaking with the oring.Too many think they must be TIGHT! and that's what kills the threads. |
