Base Board Venting Tees with Cap....not 1/8" FPT....Availability of New Caps??

BB's have the bleed caps with flat screwdriver slot.
The caps are screwed on the male threads that are cast into the vent tee.
They are just like caps on the stop & waste valves.
Any best guess as to what that thread is?
Would like to change all of them. Some plugged and some stuck.
Very difficult system to work on.....boiler drain plugged.....no floor drain....no isolation valves. For 2 elderly women. Installed in late 70's or so.
Thanks for the help.

These bb vent tees were probably fairly common in the 70-80's.
The cap has a bleed hole in the side with small rubber flat washer inside the top of the cap to seal.
I did get the leaker to seal by putting some Teflon up into the cap.
I should have tried an 1/8" coupling on it while drained down.... .
The screw slots on many of them are worn out.0 -

Thanks Ed, where did you get the replacements other than rob them from another valve?
These seem more robust than usual and have the screwdriver slot on the head.0 -
Order these

If they dont work you can used the gaskets

Thanks, pecmsg.
I might try something for gasket material in the caps.
Without the screwdriver slot they would be a real PIA for this situation.0 -

There's your fitting:

You could always solder a brass nut or short screw on it to turn it with a screwdriver or nut driver.1
