Threaded Fitting For Temperature Probe

[Jeff Balazs]

Hi guys;

I have been trying to locate a new fitting for my flathead 6. I don't know the proper name for it....but it is the 3/4" fitting that screws into the side of the cylinder head that accepts the temperature gauge probe and threaded fitting.

Does anyone know of a source for these? I tried Roberts but that was a no go.

 

Thanks, Jeff

have you tried VPW?  They have lots of engine stuff.  Otherwise maybe a donor out there someplace?  I looked thru their site and didn't see it in the "engine" section, but I see they have Offenhauser Dual Carb Intake Manifold & Linkage Kits for all Dodge 230/218 engines now!  Or try Midwest Military.

You should be able to buy a new one. Follow the link below.

If you don't want to wait the shipping time that Don C's link might involve, go to your local bubble pack auto supply store and buy a "mechanical" temperature gauge for about $20. They come with an assortment of adaptor bushings and one should be the right size.

Stewart Warner makes an "assortment kit" that any good speed shop should have.  I guess if you don't find the part you could contact Stewart Warner directly.

Try home depo the sprinkler section they have brass and metal fittings. They should have it. They call it a reducer fitting.

It's called a gland nut. If your check the Tech Tips on the temperature gauge sender replacement their is some info. It is a special nut specifically for the mechanical temp gauge. VPW or Parts Voice would be good choices for a source. You won't find it at a parts store. 

Pretty sure the mopar part number is 50 291.

Jeff, I've got a bunch!!!!!

I'll put one in the mail today.

 

PS If anyone needs a new brass gland nut, shoot me a PM. I've got about 20 of them.

Thanks Guys;

I knew this was a special fitting as I had already tried to find it in the plumbing supply house and the local auto parts houses.

It has an internal collar or stop that the temperature probe and retaining nut have to fit up to.

Keven......Thanks I will take you up on that. The old steel part I have is just too iffy..............

i have a bit of a size issue with my bulb. it appears that someone may have put a new gauge in the truck but the bulb that it has is larger then the one that was in the head. the new bulb is a tight fit into the thread in the head making for no room for the nut. any ideas

 Dave ,  What I would try first is a sharp probe or screwdriver to see if there is some build up in the hole . You might also remove the gland nut to get at any build up easier .  I have had both the longer bulb and the shorter bulb in my cylinder head and they have both worked fine . There is usually some build up around a bulb that has been installed for a while , so perhaps you have some build up farther back in the hole .  Then again , you might just have a VERY long bulb of either like used on some tractors . If you can measure your bulb of ether , I can tell you if I have used one as long .

its not the length of the bulb but the threads that are to big. The one that was in the engine did not have a gland nut and threaded right in. the one attached to the gauge is a larger thread and will not thread. I will see if i can find a reducer that may work.

There are 3 different sizes that come with the universal gauges I buy.

 

On the right is the stock size.
