Help Identifying Maid o Mist Steam Vent Model #

rbamato3

Hello,

I was wondering if someone would be able to help me identify the Maid o Mist vent model on one of my bedroom radiators? See picture attached. We just bought a home in Northern NJ and we wanted to replace 2 of the hissing vents.

I already identified the other bedroom Vent as a Gortons No. C but this one doesnt look like it has any distinguishable engravings other than the "15".

See the number or letter stamped in the vent port at the top. They use the same body on all their vents and stamp the port size right next to the port. These ports are interchangeable, so if you can't find one of the same size, you can buy a different one and swap the ports.

Look at the top of the knurled orifice on the top of the vent. It will have a stamped number or possibly letter. But it should be a number.

Tell us more about your hissing vents? Do they hiss steam, or just air?

Replace the Valve with a Hoffman 1A , The Hoffman is a better vent and it's adjustable .

Actually, FWIM, I found they were hard to adjust accurately if you need a slower vent, which most people do, but may not realize they do, and in many cases noisier than my MoM vents. It a good catch-all however with a very wide range.

Vent-rites cost more but work far far better than anything else I‘ve tried. Although they too can whistle. Gordon’s are better quality but not adjustable by changing orifice.

Chevy or Ford , Hoffman or Gordon, Vent-rites , I will use them on residential, maybe , like with that problem radiator in the addition . I would use them before piping in a king vent . One of the draw backs with the Heat-Timer is that they are not a float type vent like the others .

Hoffmans have better chrome

I don't think the OP was asking for a recommendation, and recommending a 1A when you don't know the size of the vent being replaced is a bumb steer. If the MoM vent was the right size, replace it with the same size MoM or Gorton. Or get an adjustable vent if you think you might like to waste your time fiddling with it.

If that vent does not have a vent isentifier stamped on it, here are the vent hole sizes-

#4 0.04"
#5 0.07
#6 0.09
#C 0.12
#D 0.18

This will ley you know what size that vent is. You can use drills or known wire sizes to gauge them.
