RMC vent liner. Oxyyoke wads as well. Google RMC oxyyoke their website should come up.
 
Too bad.....they used to make that size, but apparently no longer. You could always make a call to them to see if they plan to restock them.
 
One of my club members uses allen head screws. He drill two holes slightly smaller than 1/16". Number drills such as a 54 or 55. The holes are in the recess of the allen head and in theory the two holes provide more head from different parts of the pan flash than one touch hole. The two holes are about the same area as a 5/64" hole so it may work. The allen head recess may provide a cone effect to direct the heat into the powder charge. Its one way to have an allen head recess and a touch hole liner that can be removed.

I am not a fan of removable touch hole liners.

Use of an allen head screw can certainly be an option when the touch hole is burned out and a replacement is otherwise not readily available.
 
These should be installed with anti-sieze to make them easier to remove, but not any more than necessary. Late TC flintlocks used these, and some guys like 'em while others prefer the semi-permanent variety. The White Lightning variety are coned on the inside and actually get the powder closer to the pan. The removeable variety seem to make more sense on a gun with patent breech.
 
You shouldn't remove a vent unless the vent hole has enlarged to the point accuracy is failing. Repeated removal wears the threads, and can lead to an eventual failure and blow out. Same for removing nipples. Use a good anti-seize, and remove maybe once a year for inspection, or if accuracy starts to fail. Just don't do it!

Oh Bologna! In lines routinely remove the breech plug for cleaning. Do percussion guns wear out from changing the nipples when they get worn out. Truth is if the threads fit right, are lubed and cleaned properly you will never wear out a liner, nipple or breech thread from the relatively few times they must be removed . The only real draw back from breech removal on occasion is the metal finish line (brown or blue) between barrel and breech.
Actually, there is a lot of corrosive damage that could be avoided if folks were not so afraid to remove breech plugs for cleaning,lubing and inspection occasionally.
Having said this it is important to have the correct tools and experience to accomplish said work successfully. Any good gun mechanic would have little trouble with a liner or breech plug removal and re-install.

I watched the Pedersoli video on flintlock maintenance.
They removed the vent liner for cleaning.
Just saying....
Since this is flints, I'll just make a quick comment, but I will remove the nipple of a cap gun and clean it every time.
Flushing a patent breech for a good hi flow cleaning works great,
Maybe that's why TOTW and others carry a special nipple with a rubber gasket and tube kit for flushing.... that works great for a spic and span breech.

The Allen keyed vent liners showed up yesterday.
I will change the vent liner out at the next cleaning on the Frontier(s)
BTW, the Frontiers appear to have a small flash channel drilled out the bottom of the plug into the drill hole for the liner, like a vertical patent breech that runs from the main charge to the area directly underneath the vent.
From the initial look, it would seem to be one of those problem areas that could cause ignition issues, but after several hundred balls out of the new .54, not a single fail or even a slow light off has occurred. That MIGHT be because I keep it clean.
 
The best vents are internally coned. The internal cone brings the powder of the chamber closer to the heat generated in the pan.

The internal cone can be a through touch hole that has been internally coned by a coning bit. I used a diamond burr to make an internal cone on my Harper's Ferry 1803.

The internal cone can be part of a vent liner such as the Chamber's White Lightning which after installation can not be removed unless you use a screw removal tool.

A vent liner with a screwdriver slot can have an internal cone. May be a slightly smaller cone than the cone in a Chamber's White Lightning.

The hex socket vent liner makes the cone external and makes the path to the powder charge longer than the above flash channels. The external cone can work with pan powder up to the level of the vent hole.
