I came across this nipple today, notice it is longer than the one on the right. Never seen one so long. Anyone know what i have here? The one on the right is a stock t/c nipple for my renegade.

Due to their hammer throw, most T/C's require the short nipple to the right in your pic.
Many other guns, however, have the same nipple threads, but require an oversize/longer nipple like the one on the left.
Since it can fit many different guns, there's no way for me to tell, w/o the gun in hand.

Nipples are going to vary depending on what gun they are intended for. pietro sums it up well. the nipple portion will vary in length and the thread length will also vary. Example: on an under hammer rifle, such as a H & A or similar, barrel sizes vary across the flats as well as the calibers - thus - wall thickness of the barrel varies as well. You want a nipple with a threaded portion long enough to go to the bore - which will help prevent fouling buildup in the nipple hole in the barrel - but you don't want it so long as to where the nipple extends in to the bore where it could also catch fouling as well as patches on a jag when you wipe the bore.
On a side lock, the hammer cup must strike the top of the nipple so the cap goes off. Too short of a nipple and it won't go bang - too long and it will hammer it more quickly ( i.e. peen it). If you custom build a cap lock, whether it be a patent breech or a drum and nipple, you have to position the lock and lock mortise so that the hammer will strike the nipple correctly. If there is a problem and you goof up - it can sometimes be taken care of by using the correct length nipple to insure that the hammer is sticking properly.
On yours - take some measurements and figure out the thread pitch and then you can compare it to those listed in Track of the Wolf listings and maybe figure out what it is for. The link to their nipple list is:

The one on the left looks like the one on my Lyman.
It is a standard 1/4-28 thread, just the top is a bit longer.
It's very possible that the longer one is from an older TC. I purchased my TC Hawken back in the 70's, much later I ordered replacement nipples from Thompson Center and discovered they were over .100" shorter then my originals. I contacted Thompson Center and they said the replacements should work. I ordered Tresso (Ampco) replacements of the original length.
Here is the whole story,

Attachment 203030 The long nipple is what my H&A came with.
#11 Nipple I.D: Longer one. Looks like a Knight Red Hot aftermarket replacement to me.
Thanks for posting the H&A underhammer pic. One of my bucket list guns!
