Photo of lubricant

Here is a photograph of the stove valve control lubricant.As you can see it is a lubricant not a sealant. It smells like lubricant, looks like lubricant and feels like lubricant, so it must be a lubricant. There was no Materials data safety sheet or spec sheet. It just is what it is, a valve lubricant. I hope this clears up the stove valve lubricant thing.

The thread sealant does double duty as a valve lubricant. Look at the detail.

I don't know if they sell single tubes.

the valve lubricant Tinsel Loaf found is correct for internal valve use. Thread sealant is a whole other topic.
Thanks Tinsel Loaf

Update to an older thread...
One of may stove valves has a miniscule leak, it will barely make a soap bubble but if left alone for a full day it's possible to catch a whiff of the bad news of a propane leak in the trailer. I finally found a source for the valve grease-
High Heat Graphite Grease - 2 oz., Gas Accessories at Instawares

As posted above, it's kinda pricey but at least it's available.

Talking Valve Grease and valve for themostat

We had trouble with leaking valves too and we're told to get all new valves. This was way too much $$$$. Long story short > our home appliance serviceman turned us on to a product by the name of Vintage Range Valve Cream. It worked like a charm. Haven't had one leak in 4 years now. The thermostat was also bad and the same company fixed it. No mo' problems....momma's HAPPY! I can't remember the site where we got it, but just Google, Vintage Range Valve Cream and that should get it.
Does anyone know a great metal polish for aluminum that doesn't streak?

Happy Travelin to all!

A follow up to my gas leak problems.

The original problem was dried and cracked pipe sealant where the valve threaded into the manifold - no problem to fix that. Unscrew the valves , clean the threads and reapply thread sealer.

Where my plan took a left turn when I decided to rebuild the valves. I took them apart- no big deal, just push out the roll pin and they come apart. I then cleaned everything, regreased and reassembled. Here's where the brain took a major vacation...I should have remembered that some valves of this type are INDIVIDUALLY lapped to make sure they seal...well it seams these are built that way. I don't recall makin an effort to get the core of each valve inserted back into the original body. So i've been fighting a small leak- so small I tried several tricks to locate it to no avail but it would still leave a small hint of gas if I left the propane turned on.

I built a tester from an engine vacuum/pressure gauge and a syringe.

By removing the entire assembly and taking off the orifices I could pressurize the manifold and fill the back of the valves with soapy water. Bingo, 3 valves foaming! Keep in mind it takes very little pressure, I used 2 psi which is more that the regulator outputs.

To fix them, I used the old style toothpaste (with a gritty texture) and relapped the valve insert into the body. DONT USE VAVLE GRINDING COMPOUND! the brass is so soft it will leave gouges in the assembly (ask me how I know...). I used a drill with a wooden dowel sized to press into the knob end of the valve insert and could spin the insert. It only took 30 seconds or so to get a good fit.

I could then reassemble and test for leaks by pressing the syringe to build 2 psi in the assembly, squirt soapy water on the valve exit and around the shaft to watch for bubbles.

So far - no leaks!

Too many photos for the upload - more in the next post. Here are the assembly details

And here are some photos of the device I used to pressure test the assembly.

new question - old thread

My stove burner valves on my Tappan Mity Mite LP stove (1963 Airstream) show a very minor detectable leak with one of those very sensitive electronic gas sniffers.

Here is a picture of one of the 4 valves. They look different than the previously posted picture,

My question is how do you disassemble to clean and lubricate with valve grease???

It is probably simple, but it is not obvious to me.

Thanks,

Thanks Gary.

I was hoping to do this myself. Can anyone offer advise on how to disassemble the valve?

Mike

Can you post more and better pictures?

I can't see much.

In general these gas valves are of the tapered plug design. There is a tapered core with a slot or hole in the middle and a handle attached at the top (wide) end. I've seen two designs, one uses a retainer mechanism at the bottom end, either a C clip and spring or a locknut, the other has a retainer mechanism at the top made of a clip that screws into the valve body.

Either way, with the gas supply shut off, you remove the retainer clip or nut (as the case may be), and pull and twist the valve core out by the handle. Clean, grease, reassemble, cook.

Here are better pictures of my stove top gas valves for my 1963 Tappan Mity Mite range.

The is a hole in the collar of the valve nearest the knob. I don't see what its purpose is. I think I should unscrew this collar and the internal valve will just come out. But before I do something that causes unrepairable damage, I need some technical advise on how to dissasemble these valves.

I hope someone can give me a hand.

Thanks,

My newly aquired '63 has a Tappan...I'll try to look. I'm thinkin there is a pin that you push out of that hole when it's turned to the right place - then the spring loaded guts will come out.
