I have a 60 gal vertical compressor that has a leak at the large nut
where the regulator is threaded into the tank.
It is leaking around the large nut itself. This is not something that I
Will an epoxy seal and problem? If so, which one?
I'm assuming you mean there has been a failure of/at the weld between
the tank and the nut used to mount the regulator. If so, how old is
the compressor? If new, complain to the manufacturer and _maybe_ you
can get relief. If old, it may be an early indication of water/rust on
the inside of the tank.
Best would be, of course, to repair it if you're handy w/ and have the
facilities to weld it.
Depending on the size of the hole and whether it is just a minute weld
imperfection that has failed and not a larger corrosion area that has
"thin-walled" the tank so it's getting ready to leg go in a larger
area, you may be able to get by w/ an epoxy. I'd probably look at one
of the "metal-weld" types (and make sure this area isn't pointing out
into the shop where if it lets go it isn't aiming at me)....
If it's and old unit and there's an indication of rust or water
accumulation, consider a new tank is in your future, probably.
I think I would be looking at a new tank , if its the weld that has

If its a real small leak, it's not really worth the effort. Mine will
depressurize overnight, and has for years.
If a 4' cheater pipe on your wrench won't work, if its just a small leak around
the threads but it is too rusted to get off, something like JBWeld might buy you
some time to shop.
I understand it gets thinner when warm, and pulling a SMALL vacuum on the tank
(vacuum cleaner on drain line, maybe?) may help draw it in like a thread sealant
/ pipe dope. I also understand that you would never get it off.
I've even seen paint work. Tank must be depressurized, of course.
If you think there's been any damage beyond what teflon tape would cure if you
could get it off, start shopping now.
Sorry - I was taking all of that as a constant. I'd rather see the EFFECTIVE
price, and pay the actual shipping.
Sort of like hotel reservations over the Internet - sure, some discount company
may offer the lowest price, but with service fees it's often cheaper to call the
You pay for the handling one way or another -- either as a separate fee (like
Harbor Freight), or as combined "shipping and handling", or in the form of
All other things (such as delivery schedules, return policies, etc) being
equal, the only thing that matters is the total price. How it's broken out
should make no difference.
If the tank is old, it's time to replace it just for safety sake. When
one leak starts chances are another will develop. Anyway, if you
still want to try a sealant consider JBWeld (available most hw stores,
Lowes or BORG).
