Boiler Putty

PostBy: billw On: Thu Sep 04, 2008 11:04 am

Ok, this is probably going to get the dumb question of the year award but here goes.

Is there a difference between boiler putty and furnace cement? The manual and the refurb guy specifies using boiler putty to seal the boiler to the base. I've been to both local big box stores locally. The only thing I see is plumbers putty to seal sinks etc. I asked at a local plumbing supply house about boiler putty. The counter guy told me he never heard of it and I should just use furnace cement.

I used furnace cement originally when I put the boiler on the base but my neighbor rocked the boiler on the base when we were trying to get some old fittings out. I cleaned out all of the old cement and am ready to replace it. So is furnace cement acceptable or are these two terms for the same product?

The efm 520 comes from the factory with a 5 lb tub of
" s o s boiler putti"
stock number bp-5
from s.o.s. products company, inc.
east greenville pa 18041

The tub says on it:
"A ready to use plastic putty for sealing joints of heaters, stoves, and sectional boilers against gas and air leaks when flexibility and not high temperature is the factor. If thinner consistency is desired, add a small amount of any type of oil and knead in thoroughly."
The web site seems broken but is here:

They say not sold in home centers..
I imagine efm would sell you some, they seem very helpful.

I am using cement. that is all I could find ANYWHERE in my area.

As far as the temp I think there are some pretty high temps on that boiler to base joint... i'm guessing... So I think temp is an issue on the EFM.

My take anyway...

Any answer on this? I called a couple of places around Binghamton today and no one carried putty. The one guy said it wasn't the same as furnace cement. He suggested Hi Temp Silicone sealant. I believe stokerscot said he used silicone also.

Furnace cement is fine but it cracks & gets brittle when it dries out Plummer putty can be bought at any Hardware store or any of the big box store I bought 5 tubs of it at lowes for 4.74 a tub All you are doing is keeping the outside air from coming in and keeping Co from coming out Plummer Putty will work Just Fine works Just like Boiler putty ;)

Thanks JC. I guess the heat from the boiler won't screw it up?

I would use hi temp silicone.Plumbers putty dries out fast when there is no water on it.

John, I used silicone for around the mounting plates before the bolts were tightened. For around the base connection I used door gasket material and pounded it in with a screwdriver and a hammer. It works fine. If it has to come apart there is no cleanup. :) Scott

Not as much as Furnace cement does Boiler putty or Plumbers putty will last 40 or more years on the base you have to
chisel it or wirewheel it out when you refurb them I just removed a 1968 today You have to use a pry bar to separate
the boiler from the base That Putty is Tuff I also seen a 1948 520 Highboy that still had all the putty around it and about
50 or so other units with the Putty still in them They come from the Factory with a tub of putty it works

I sort of like the idea that when I'm downsizing and getting ready for retirement, that I can take apart the boiler without too much trouble and move it. Put it back together without any trouble. Mine's a '60 with the heat exchanger. As long as I stay 1 year older than it, then everything will be fine :lol: Of course, as soon as it pulls even it won't matter :) Scott
