Does anybody know what the source for this tubing cap is?

   I don't have a source, but it is a rivet of some sort, probably for leathermaking.

That does look like a "Fuel Dot" from Central Hobbies in Billings, MT.

Most CL guys use a BB in a short length of fuel hose.  y1 Steve

Aluminum rivets I used to get from McMasterCaŕr 1/2" or 3/4" long . Great for altering fluid flow paths in valve bodies

Brett,

It does look like a universal aircraft rivet, but it is hollow on the end being inserted into the tubing. I contacted Warren Wagner the guy I got the plugs from who is about out of the hobby. He couldn't recall but thought it came from some hobby source in Canada that supplied "the thin white wheels" if this makes any sense.

That is a stock 1/8" tube rivet.   I use them for making control horns and such.   Available at Ace Hardware.

  1/8 is barely big enough, 5/32 would be better.

I bought a roll of aluminum clothes line wire from the local hardware store.  It's a good sung fit in 1/8" fuel line and you get a lifetime supply for a decent price.

  I've used just about anything that will plug the fuel line securely. Standard BBs work very well, and I imagine pellets for a pellet gun will also?? Any 4-40 machine screw turned around and force the head into the tubing ( good for at the flying field), Dubro makes specific plug fittings and so does Foermost products, any kind of rivet,  anything that the tubing will latch on to and seal tight. The COOLEST thing to use is the pegs from a Lite Brite kids toy!! That's a tip I picked up from a Windy video. I take a pocket knife and cut a swirl hatch pattern on the socket end so the tubing will grab better. They make these in a long end but the shorter end is more common. If you drop these in the grass, they literally glow in the sunshine and are easy to find.  That's gets more important as you get older!!

I agree with Dan.
The guys on Stunthangar hangout informed me of them. So I tried them and they work great.
What I did was look in the GoodWill stores until I found a Lite-Brite set and took a goodly supply in different colours out of it.
Then I gave the set to a neighbourhood kid.
Everyone wins!

Ah the creativity of model airplane builders! I like the Lite Brite idea, but I won't find any around the family with all the young grandkids, too easy to swallow. Turns out I found a stash of AN rivets from my old RV9 building days and they work just fine. Thanks much.

   I think you can buy extra Lite Brite pegs seperately. I have found a pack or two in my toy show hauntings, and never had to buy the whole toy. I'm not really sure who even makes the toy but I think it's still in production, but not suggested for smaller kids due to the small parts issue.

steve,

Dave is correct.....it's a common RIVET and I bought  them at ACE hardware.

I went to the airport were they do some aircraft repairs. The mechanic gave me a few for free.

I was installing a new bathroom sink and had to cut down the rods that open/close the drain. They were 5/32" diameter and I instantly thought of this thread then cut them into 1/4" lengths.

MM :)

I went to the True Value Hardware and found the tubular 1/8" zinc rivet mentioned above. They want .30 cents each, way too much for my wallet. On the way home I stopped at a specialty fastener store and found they have a solid aluminum of the same dimensions and paid $2.00 for 100. They only had 7/16" long rivets but I can easily clip it to 3/8" or shorter. The solid aluminum actually feels lighter than the zinc (didn't weigh) but certainly lighter than the harder aluminum AN aircraft grade rivet I have in the shop. My search is over, Thanks much.

A 4-40 x 1/8" socket head cap cap screw works. You just have to push it in so the top of the head is flush with the end of the tubing and that the head of the screw is completely  imbedded in the tube. Difficult to put on and take off but that might be a good thing.

 Good luck finding the plug if you fly on grass. The older versions of the Battleship game are the best plugs bar none. Everything else is just foolishness. 😄

Good idea, I've also used red cribbage pegs, leave them intact for grass, cut them at the tube for pavement.

Yes, I cut the pegs that I use for plugging up the uniflow vent when I'm done flying. Otherwise I leave a trail of drips up the sidewalk of the house. Game pegs matter.

Dubro makes a nice compact plug ( https://brodak.com/dubro-fuel-line-plugs.html) not bad at $1.87.

This is what I use. And like Dan saw it on a Windy video. 😎
And you can match it to a color on your plane too. 😉
