    Leaky oil sight glass on vac pump

    Any body got a fix for it? The glass is pressed into the shell.

    What brand and how old?

    Maybe some JB weld and pull a slight vacuum on it. I repaired many studio apartment size refrigerator evaporator coils with this method.
    May not look to pretty.

    You should be able to hook another pump to the oil fill plug threads, Maybe???

    Hell yeah! No maybe about it. That's a great idea...have to keep the oil level just below the sight glass to maintain a tight seal from the rest of the pump.

    The head on my pump is new. Unscrewed the brass hex nut holding the sight class...no fricik' O ring! Scavenged the O ring from the old head ...screwed the brass back in...leak stopped.

    That's good news.

    I had an old Welch Duoseal pump that dribbled oil everywhere. Never had to change oil in it, just topped it off now and then.
