Can I get a little help from someone knowledgeable on this. I have a new Uberti 1858 Remmie. Looking to replace the factory nipples with Ampco bronze nipples (?Tresco?). Is the following the correct nipple to order. This is a .44 caliber full sized Remmie (non-stainless). I assume we can ignore the ".31" in the description.

Ampco 5.5-.9mm metric thread

Clembert-
I am not knowledgeable-coming back to BP after being out for 30 years but I have checked with the fellas at the Possibles Shop and All TRESO nipples take #11 caps. The Cap & Ball Nipples are listed on http://www.possibleshop.com/s-s-nipples-cb.html
I will get a set of them for my Uberti 1860 and if all is good with #11 fitting real well then I intend to use the Treso's to replacements on all of my pistols.
 
There is a overall size difference in the nipples for different revolvers other than the thread differences. The Walker and Dragoons take a large nipple, the 1858's, 51,60,61's take a medium or standard size and the pocket revolvers take a smaller size.
 
I don't know if it's a typo. I know it's wrong. For one thing, the pockets and the 'midsize' guns DO NOT use the same nipples.

Ubertis use SAE nipples, at least the bigger guns do. The horse pistols use 1/4-28, the Army/Navy guns use 12-28.

I think the pockets use the 5.5mm-.9...they're smaller than 12-28, anyway.
 
Admiral B is correct. I thought, erroneously, that you had a Pietta so my posts on this thread and TFL were incorrect.

12x28 is the same size as the metric 5.5x0.9. Ordering either will work. The No. 12 thread major diameter is 0.216 inches which is 5.5mm. 28 threads per inch is a thread pitch of 0.907 mm.

The Track of the Wolf part number for the Treso nipple is PCC-A; Treso's part number is 11-50-16.

Take the nipple to your local hardware store and have them measure the thread, but I'm sure Admiral B's message is correct.

The Dixie catalog is wrong on many levels. First, there is no such thread as '6mmx9' (assuming they mean 6mm MD and 0.9mm pitch). The Uberti Walker and Dragoon use 1/4x28 thread nipple. Next, the '5.5mmx9' spec has the same error (9 should be 0.9); that thread size nipple is used on the mid sized Uberti guns, but the callout should really be 12x28.

Okay guys, I appreciate your help in clarification on this. It kind of sounds like we went a little bit in a circle and came back to the starting point, LOL. I didn't bother trying to make sense of the metric measurements as it relates to 12x28 but I knew some smart fellas would come around shortly with the answer. It is truly amazing how hard it can be to get official error free specs on nipples short of calling the factory.

Kind of strange that TotW has PTC-PA (5.5mm x 0.9) and PCC-A (12x28) part numbers when they are both one and the same...or am I wrong? :confused: Further, its funny how there is a price difference between the two.

Track isn't quite telling the whole story. The difference between them is length (height?). The PTC-PA is longer than the PCC-A. Just to make it more interesting, there's also the 12x28 PTC-A which is the same Treso part number as the PTC-PA. Track doesn't (nor does anyone else I'm aware of) publish the length (height?), which is almost as important as the thread; instead, they use the OEM gun description that's often confusing.
 
Thank you sir. I went ahead and ordered the PCC-A (12-28 thread, for Colt revolvers, #11 cap, Ampco bronze) nipples from Track of the Wolf.
 
Hmmmm y'all, what can I say....I'm stumped. I tried to do my homework before ordering nipples but I FAIL. :cuss:

The Treso nipples came in and it's a no go...too big. I could see that before I even tried to install them. I ordered Treso part number 11-50-16 (PCC-A from Track of the Wolf). The description on the packages says: REVOLVER NIPPLE 12-28 THREAD FITS COLT, NEW ITALIAN REVOLVERS 11-50-16.

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

The Treso nipple will fit in my ROA. Too bad it is shorter than a ROA nipple though. The Treso nipple obviously will not fit in my Uberti 1858 Remmie. The ROA nipple will not thread into the Uberti. The Uberti nipple will thread into my ROA but you can tell the thread is a bit loose. Anyhoo, this tells me that the thread pitch is the same for all three nipples.

I took it a step further and went to ACE Hardware in an attempt to further determine thread size. All three nipples would thread into a 6mm x 1 nut but not the 5mm x 1 nut. This told me nothing because I knew that before I went there but those were the only two choices that ACE had.

So...what SHOULD I have ordered? :confused:
 
Interesting...I just pulled nipples from my 1858, 1851, and 1860. They all measure 5.41mm major diameter.

In fact, the nipples on the old Leech/Rigdon cylinder I picked up also measured 5.41mm.

They're not all identical in appearance - the flanges are thicker/more squared-off on some, and the transition from threaded- to unthreaded sections differ...but they all have the same thread pitch/size and the height is the same.

I wonder how old your gun is...what's the date code (two letters, stamped with a box around them...should be on the right side of the frame)?

Sounds like your gun has the same nipples as my 1862 Police.

Made in 2008 (CC).

What size are your 1862 Pocket Police nipples?
 
ClemBert: I don't understand a Ruger nipple not threading into your Uberti, they have the same thread, and I have Ruger and Uncle Mike's Ruger nipples in several of my Uberti Army and Navy cylinders. The Ruger nipple is a bit shorter than the Uberti in order to allow the Ruger OA to be dry fired, but they work in an Uberti, even without a shim washer.
 
Well, by golly. The 1862 nipples are 5.35mm.

Sounds like yours got made with the smaller ones...dunno why; my Ubertis (except for my Walker) are all 2008s also.

Anyway, that would be 11-50-30, in Treso-speak.
 
Take the nipple out and measure it with dial calipers... I would suppose it's possible to have gotten a cylinder with the 5.35 dia meter threads.
You do have a Uberti Remington correct...I kinda lost track with all the replies. :O)
The Standard midsize Uberti Revs take 12x28 threads as Does Armi San Marco. Pietta are 6x.75mm threads...of course there's the Pocket cylinder and believe they are the 5.35 dia threads. Both take the No'11 caps.
 
He's got the fancy Uberti with the cased frame and charcoal barrel and cylinder. Should be 12-28 but sure sounds like his got made with the Pocket nipples.
