Brass Solder Pipe Fittings

Recommended Posts

Does anyone know what these type of fittings are officially called, and where one might buy some in the US?

 

The first image is the Franklin drawing of the vacuum line from intake manifold to vacuum tank

The second image is the type of fitting that it is.

When I search Google for "solder nipple" or "brass solder nipple" it only seems to be able to turn up that they are still available in the UK, but then the nuts seem to have British Pipe Threads on them, not US threads.

 

I need 2 that go on ¼" copper pipe and have 7/16-24 threads on the nut.

 

Also in an ideal world these would go on nickel plated ¼" copper pipe, but I can live with regular copper pipe and maybe get that plated at some stage when I'm feeling really genuine.

 

Thanks!

Obviously you mean 1/4" OD pipe. You may have to find some one with a lathe. Not too difficult a job. 7/16-24 thds are an odd ball but taps are available or they could be cut single point.............Bob

1 - yes ¼ OD pipe

 

2 - the threads on a ¼" compression fitting nut today are the required 7/16-24, so I already have the needed nuts - just need the fitting.

 

Yes - I could make them if I had a lathe - I'm not sure my wife would consider these two tiny brass things sufficient reason to buy one though LOL

Another way round it might to be slip on an appropriate length of brass, put a (double) flare on the pipe, solder the brass on behind the flare and do up the nut! Perhaps the flare would be too small. Then flare the larger pipe end after it is soldered on.  B)

If you can provide a dimensioned drawing I'll make couple for you. Un-plated brass, you pay the shipping. The nut has a tapered seat to squeeze the ferrule. That  taper should be removed to make the seat flat. Shouldn't be a big deal.......Bob

@Bhigdog Bob - thanks so much for a generous offer. If you're up to making them I'm certainly up to paying for postage (and buying you a beer if that helps...)

 

The attached image is based on the Franklin engineering drawing. Assuming ¼" for the pipe diameter I've interpolated the other dimensions, also mindful of the nut that has to go over this to screw on to the fitting. I do have the original Franklin fitting for one end of this. It has a tapered seat that would pretty closely match the seat angle shown in this drawing. The fitting I have for the other end is a regular US compression fitting and the new pipe fitting for this should seat into it with no problems.

Hopefully it's not too difficult to make - the wall thickness isn't great along the length D: (C - F)/2 = .030"

 

Let me know if you think this is too finicky - I was going to try and source some from England where they seem to be still available - although the nuts they sell won't fit the US threads on the fitting, but the "olive" should fit the ¼ pipe.

Hi Roger. I think I can help you out. It would have been nice if they called out the taper's angle but I think they give enough info that I can trig it out. Can you send the drawing to me by separate EMail. That makes it easier for me to print it out.   bhigdog1@ptd.net.  ..................Bob

Check out John Deere two cylinder tractor engines.

Deere used those extensively throughout the two cylinder era.

Kiwi did you try a welding supply house. Those look like the fittings on a gas regulator. If not them how about McMaster Carr Supply

 

They are way smaller than the fittings on a gas regulator, and a different shape.

 

McMaster Carr don't have anything anywhere near resembling them.

Well - would you look at that - this is for 5/16" tubing (I need ¼ - I have the original 5/16 ones that are on a different line). But hey - they exist...

 

https://www.steinertractor.com/JDS1011-fuel--oil-line-gland--nut

 

So now we learn that they are called a "gland nut" apparently - Ebay has a number of them for sale in the UK

 

http://www.ebay.com/sch/i.html?_odkw=gland+nut&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.Xgland+nut+olive.TRS0&_nkw=gland+nut+olive&_sacat=0

 

but these all have BSP (British Standard Pipe) threads on the nut, so won't fit my fittings.

FWIW...... there is some nomenclature license being taken. A gland seal is used to seal a rotating or sliding shaft. Usually the gland nut compresses a soft seal as it's tightened to effect the seal. Think older faucet stem or older water pump. Not sure what you call the part needed here. If I had to guess I'd call it a type of ferrule..............Bob

 

McMaster does have something similar. They call it a flared tube fitting...............

Yep - don't disagree with that!!

Solder nipple seems to find the most results for it on Google.

 

I think of ferrules as being thin, and providing the clamping force themselves - e.g. the metal band around a paint brush or the metal band at the end of a wooden handle on tools like chisels or the "olive" in a compression fitting.

I'll post a picture when I have the pipe made and fitted to the car.

Good, glad they arrived OK. They're made to print so hopefully should be fine. .................Bob

And today I got the pipe made with the fittings, and connected to the vacuum tank which I'd put on yesterday.

 

Again so many thanks for your help @Bhigdog Bob!!!!

Very nice and neat work, Roger. I was hoping everything would fit. It was a fun little project. Thanks for sharing.............Bob

Thanks Bob

 

It's great that so many of the drawings for the parts of this 90 year old car still exist and are available to H H Franklin Car Club members through the club's website, so replacement parts can be made to the original drawings.

If you need any more doohickeys fab-ed up let me know. No promises but I'll take a look. How about a few pics of your car?................Bob

This was the last time I had it out in the middle of December for a driveway photo-op. Hopefully you can see these even if you don't have Facebook?

Just in case, here's a photo of it here in this post when I bought it at Hershey in October 2016...

And here it is being delivered a week or so later...

The doohickey project was because it had an electric pump on it when I got it - and a non working vacuum tank that had been removed. I've had the vacuum tank looked over and tidied up and fitted it back to the car, but didn't have the pipe that the doohickeys went on today.

This may be the first time in history I have not had a problem with your posts Bob! :)  Actually, I wanted to commend you on helping out Roger.  It renews my faith in having this forum.  Kudos to you!  (not sure what a Kudo is but it is being sent to you anyway!) :)
