The Stovebolt Site Forums The Shop Area Engine Shop Brass oil gauge fitting

Anyone know where I can get the brass fitting that connects the 1/8 inch line to the back of the oil pressure gauge & to the lower engine block,with out buying the kit which includes the oil line? part # would be great.
Thanks

You may first try NAPA they still carry some "weatherhead" items fittings and the like next some one might have an extra one here.
mike

yes, i got that exact thing at NAPA. the clerk guy got it from a drawer near the counter - i never would've found it.

Here are T fittings that NAPA has or can order:

This is the 3/8" T that is often used.

Tim, it's not the Tee..it's the small compression fitting that goes into the back of the gauge

Jimmi, I think what you’re looking for is just a 1/8" compression nut and compression ferrule or sleeve. If your FLAPS don’t have them, (they should) then try McMaster Carr online they will have it out to you in a day or two.

Thanks,...I gave up and ordered a new set with line from Classic.

Sorry, Jimmi,

Is this the part you are looking for ?
compression nut


Tim

Tim I do believe your are correct. Just went out and took a look at the '50 and the '54 and both use that double compression nut. That is the same type nuts that are used on the cross-over oil line that passes thru the water jacket on the early engines cept these are 1/8" instead of 3/16". The back of the oil gauge is machined to take that kind of a male compression nut. There is a matching double compression connector that is used on the oil lines.
These are kind of hard to find as anyone that has spoiled their cross-over oil line can tell you.
This type of compression nut normally is a one time shot. Once the nut is tightened down it pinches it's tapered end down on the line and usually you twist the line when you try to back it off.
I suppose the reason they didn't use the Nut & sleeve type fitting, which can be disassembled a few times, is because the connection was only meant to be a one time shot not something that would be assembled and disassembled many times during the life of the vehicle. Which was only meant to be about a decade.
Now, how did you find that in their online catalog??? Every time I try to find anything like that on any of the auto parts catalogs they all want the make and model of the car or truck and I can never find anything strictly by the part number.

Denny,

Fastenal and NAPA both had that 1/8" ferrule in stock. Fastenal also had 1/8 copper refrigeration tubing (by the small roll), and Fastenal required me to buy a pack of 12 but NAPA sold ferrule by the piece (and, had it in stock).

I found the Weatherhead/Eaton part numbers in their catalog and then used that part number on the NAPA website. If NAPA does not have the part in-stock (or, in their on-line catalog), they will usually order it (if you have the Eaton part number).

Tim & Denny,

Am I confused (as usual)?

I think Tim's style of fitting (1/8" compression nut (Eaton 6100x2 1/8" Threaded Sleeve Nut - no need for a ferrule with this) is used at the engine-end of the copper tubing. That fitting is also available by the piece at NAPA (and probably elsewhere - Eaton makes it). If you want a NAPA number, let me know.

A 1/8" cap (Nut) and ferrule are used (I think) at the gauge end. And, thanks to Denny's info (if I understand his post correctly), it looks like that arrangement was most likely used from 47-55).

I'll go check my 54 gauge assemblies to refresh my failing memory.

Denny,I walked in the store with it in my hand years ago.The counter guy said that is"such and such part,let me go get you one".I kept the part number off of the little bag they come in,use to be sold in pairs.

Tim,The compression nut is used to screw into the oil pressure gauge.I'm not sure about the engine block side,I'll have to go look.


Tim

Yes Tim, the engine end also uses the 1/8” double compression nut on both the ‘50 and ‘54. They use a double compression male connector 1/8” tube to 1/8’pipe thread in the block.
For the nut: Edelman #111200, Weatherhead #6100X2
For the connector: Edelman #112220, Weatherhead #6200X2


Now, ya got me goin Tim, although I’ve heared ya mention Fastenal many times on the Bolt I’ve never dealt with them before. I looked up there catalog and ordered some of the above mentioned fittings. Double compression nuts were .51c each, about a third of what they are at the auto parts. And while I’m at it I went ahead and got some of the same fittings in 3/16” for the feed thru oil lines cuz I’ve got a couple of blocks that need them.
Thanks fur pushing Fastenal at me, I think I might have found a new source for my hardware items other than McMaster Carr.

Guys, I went to O'rielly ( 2 different ones) with part in hand. No luck they only had female compression type. Not male. So I just ordered the entire kit.....http://www.classicparts.com/1947-77-Oil-Pressure-Gauge-Line-Kit/productinfo/24-781/
I would have rather spent 5 dollars..than 20..OH Well
I have NO Patience....
Thanks

Denny,that is what I was thinking,but wasn't sure with out looking.
I have a fastenal 2 blocks from me,have never purchased from them.

Jimmi,now you have a part number if you should ever need the compression nuts.I'm lucky,I have old guys at my oreillys that know how to look up parts in the book and can run a computer.

Good Luck,
Tim

..recently walked into NAPA and told the guy I needed what I thought was called a "threaded tube nut" for a 1/8" line. He said be right back and showed up with one.
I think it really depends on WHO is working when you go in. Now that we've had this discussion I think I'm going to buy me two or three for the future!

Oh, and back then it was the BOLT that told me what I needed. YOu guys ars so organized Tim, you amaze me. lol

I thought I was on to what I needed based on Tim's info and the responses that followed. However I am now more confused than ever. When I rebuilt my gauges I replaced the oil gauge with a 0-60 pound unit and didn't notice the oil line hookup. I got a new oil line kit from Classic Parts and it has the correct male nuts. I saved the old engine end fitting which accepts those nuts and I believe is called a connector in the previous discussion of part numbers. I seem to recall that my old original oil gauge had a cavity the nut threaded into.

Not so my new gauge. It has a rounded end and the same thread as the male oil line nuts. Because it has a rounded end (almost pointed if it didn't have the hole) you cannot use a regular compression nut and ferule. It seems like I need a double female ended connector that has the proper flare so the nut seats. Is there something simple I am missing? Any help you guys can give me about this will be greatly appreciated. I have struck out at the three biggest NAPA stores in the area.

Hooka, As I recall,I took off the fitting on the back of the new gauge and the oil line fit right on...NOW....PLEASE use CARE when tightening the brass line onto the gauge...they are cheaply made and I snapped 2...I was so fed up I took the old gauge swapped the face plate and put on the new line...Worked perfect,and if you put the gauges side by side you can see the difference in quality.
Hope this helps

Thought we had this all straightened out a month ago. The stock 1/8" line is a copper plated steel line with two of these nuts: Edelman #111200, Weatherhead #6100X2 on each end. And the 1/8-mpt to 1/8" tube connector: Edelman #112220, Weatherhead #6200X2 belongs in the block.

The back of the stock gauge should not be a 1/16" Male Tapered Pipe Thread and if you try using a tapered pipe thread you‘re cross threading it. MPT is 1/16”nom. 27tpi and the correct double compression nut is 5/16“-24tpi.
God only knows what a reproduction gauge would have tapped into the back of it, but I would hope they were using the same thing the original one had.
That “kit” from the FLAPS with the 1/16” MPT compression connector fitting is not the correct fitting for these gauges.

To Avoid confusion I deleted my earlier post.
I see this is on older thread that got bumpped up

My aftermarket gauge Had 1/16 pipe thread on back. Not a stock original oil gauge.

Dennys diagram shows an 1/16 MPT adapter (Male Connector)to use should you find the same.

I used compression fittings on my set up.

Thanks for the help guys. I feel like a real dufus. I got a stronger light and my old man glasses and took a better look under the dash. Like Jimmi described above, there is a fitting screwed into the back of the gauge that I thought was part of the gauge. The gauge has the same setup as the original when the fitting was removed. Interestingly, that fitting is double male ended and can be reversed and then use a common compression nut and ferule. Based on Jimmi's experience maybe going this route would be better than using the original setup. At least it would be easier to remove the line if necessary.

Denny, you did have it all worked out a month ago. It was my age and eyesight that fouled me up.

Even though this is an old post I am posting this for information for others. NAPA carries an exact replacement for the oil gauge line fittings. It is part Gate G605930202. It does not require a separate ferrule and works the same as the original. Another good thing is it is less than $1.50 and you don't have to buy the copper line in a kit to get the fittings.
