A little help on nipple selection

Take the nipple out and measure it with dial calipers

From my previous post:
I pulled out the calipers and took some metric measurements on the outside diameter of the threads:

Treso nipple: 5.49mm
Uberti nipple: 5.36mm
ROA nipple: 5.41mm

Is the length of Treso 11-50-30 nipple the same as the Treso 11-50-16 nipple? In other words, IF it threads in okay is the length going to be a problem now or will it be correct?

Yes, this IS a .44 caliber Uberti 1858 Remmie manufactured in 2008. It is CCH with the charcoal blue barrel/cylinder.

The Treso 11-50-16 is the correct number for Uberti Midsize frame Revolvers with 12x28 threads.
You need to have the correct length of the cones threads and top so as you won't mushroom the cones(to long) or caps not go off (too short).
Who lists an 11-50-30 Treso ... s/b 11-50-16 for your Uberti as a standard, or pocket sized cone thread base as the Colt 1862 Pocket Police .36.
 
Just to add some more confusion to the stew:

I have 3 of the Uberti .36 cal Pocket revolvers, 2 1862 Pocket Police and 1 1862 Pocket Navy. Here are the OEM nipple sizes:

2005-manufactured Pocket Navy: 0.208"x28tpi, 0.479" overall length. That's 5.28mmx0.91mm/thread.
1997-manufactured Pocket Police: 0.206"x28tpi, 0.492" overall length. That's 5.23mmx0.91mm/thread.
1972-manufactured Pocket Police: 6mmx0.75mm/thread x 0.446" overall length

Yep, two are SMALLER than 5.5mm (or No. 12 SAE), and the Treso 12x28 thread nipples will not thread in the holes, and one, the 37 year old one, is a completely different nipple, 6mmx0.75. Go figure.

Also, Treso makes at least three different nipples with 12x28 (or 5.5mmx0.9 if you prefer) threads. I measured the ones I have and got the following:

11-50-12 (ToTW #PRA-A): 0.216"x28tpi, 0.526" in length
The package label says these are for the Ruger Old Army. The OEM nipples in my ROA measure 0.210"x28tpi, 0.528" overall length
11-50-16 (ToTW #PCC-A): 0.215"x28tpi, 0.499" overall length
The package label says these are for Colt, New Italian Revolvers.

11-50-30 (ToTW #PTC-PA): 0.215"x28tpi, 0.484" overall length
The package label says these are for .31 Remington Pocket Revolver.

I haven't a clue as to why Clembert's Uberti Remington has such an odd size nipple - likewise I have no idea why my Uberti Pocket Police have completely different nipples. And to put the final frosting on it, I have no idea what nipple to buy for my newer Pocket Police or my Pocket Navy.

I used to think I understood this stuff.

According to these measurements the answer can't be the 11-50-30. The major thread measurement is the same as the 11-50-16. The only difference is that one has a shorter overall length than the other.

0.215"x28tpi, 0.499" overall length is the same measurement I got for the 11-50-16.

0.211"x28tpi, 0.500" overall length is what I measure for the OEM Uberti nipple out of this revolver.

Its hard to believe that 0.004" is making a difference here. I should note, however, that the Uberti OEM nipples go in with very little slop. You can feel a little resistance when putting them in with the nipple wrench.
 
At this point, I'd suggest calling Taylor's. They're intelligent folks and should be able to tell you what you have, even if they don't sell Tresos.

Worse comes to worse, get a 12-28 tap and recut your cylinder...and use the Tresos you have.

I got to looking at Uberti schematics...and they all list the same nipple for all the revolvers except the horse pistols.

So I took the cylinder out of my Pocket, and tried some of the nipples that measured bigger.

They went in fine.

If it were *my* gun...I'd scrub out the threads in the cylinder real good, oil them, and run in the Tresos.
 
I haven't looked at ToTW, but 3 other outlets list their Treso 6 nipple revolver pkgs as.
PIETTA 11-50-106
UBERTI 11-50-166

Do you have the 3 links so I can take a looksie?

I threaded a wire brush through the nipple holes to clean them out. They are as clean as they can possibly be. It just isn't gonna happen with these Treso nipples. You can't even get them to start threading in. I tried three of them just to make sure I wasn't making a judgment based on a "bad" one. The Treso nipples are clearly just too big.

The difference between 11-50-16 and 11-50-166 is that the former is for one nipple and the later is for 6 nipples in a package.
 
Woot!!! :D I got them in!

I called up Treso to find out if they were aware of any "new" funky nipple that Uberti was using. They said there weren't aware of any production changes and insisted that these Treso nipples are correct to their knowledge. I told them that the nipples wouldn't even begin to thread. They did say that their nipples were purposely made to be on the high end of the tolerances of thread specifications. The reason being is that the nipples are usually used as replacements on firearms that have a lot of thread wear from years of use and tend to have "loose" holes. Funny, how many of y'all change out the nipples as soon as you open the package on your new firearm.

Anyhooo, this is how I got these suckers to thread. I happened to find one nipple from my stainless ROA that if I "forced" it I could get it to thread into my Uberti. After working this nipple a dozen times or so back-n-forth into the Uberti with anti-seize lube I found I could start the Treso nipples in. With anti-seize lube on the Treso's I was able to "force" them into the Uberti cylinder. Yes, I was cringing on each and everyone of them. As you would suspect I ended up with a bronze shavings here and there after getting them in. A very, very tight and scary fit.

In the end I think I had a bad combination of tolerances on each end. On the Uberti the 12-28 holes were on the small end of the scale whereas the Treso nipples were on the high end of the tolerance scale.

Thanks to everyone to helped me out!

I haven't had a chance to shoot it with the new nipples and powder just yet. I did fire a #10 and a #11 Remington cap on two of the nipples just to check. Got ignition!

I went slow with the Ruger SS nipples. I'd go back-n-forth a little here, a little there then pull it out to check to make sure I wasn't doing any unwanted damage to the nipple or cylinder. Anyone know how hard Ruger SS is compared to Uberti steel? I would think that Uberti steel is stronger/harder than SS but it would seem that the SS won the battle.

I have a tap and die set. I would have gone that route first but I didn't have the right size tap or die to work on the cylinder or the nipples.
