thanks guys... Yes, it is round glass.
I have tryed it with the small, thin , brass
washer and without. I will try ordering
the hight temp washers ( rubbers as I call them).
I saw them in a catalogue that just arrived.
Teflon..!! 98 cents.. part of the problem is the boiler is never on all of the time.
It runs for a few hours at a time. The washers
cool off and dry out too often.

Is this a round gauge glass? If it is, the first thing I'd check is the washers you're using. The ones you've got are probably for low pressure steam, or more likely, an expansion tank gauge glass for a hot water system. Make sure you've got the proprer ones, and are rated for the service they're in. If you ask whoever's supplying them about what temperature your current washers are good for, and he says "Huh?", you're talking to the wrong guy.

: I agree with Tom. But One more secret: if it is round glass, wery importent is how you arrange the washers on the glass. Besides of rubber washer there should be a tiny brass washer. The order how you arrange this should be this: rubber washer - brass vasher - flare nut, rubber washer face to cock valve.

: Hope it will help.
